The morphology, crystallinity and hydrophilicity of tantalum-induced fibrous membranes were investigated under different material and solvent conditions. The results showed that the conductivity of the spinning solution and its ability to generate induced charges in the electric field were enhanced by dispersion and charge migration, which in turn induced the jets to be stressed in the electric field and form finer fibers. Scanning electron microscope (SEM) and transmission electron microscope (TEM) analyses showed that the charge transfer behavior of tantalum particles promoted fiber stretching, leading to fiber diameter refinement. X-ray diffraction (XRD) and infrared spectroscopy (IR) analyses showed that the incorporation of tantalum particles induced the transformation of P(VDF-TrFE) from α-phase to β-phase, but had less effect on the crystallinity of PCL and PLA. In addition, hydrophilicity tests showed that tantalum particles reduced the hydrophobicity of PCL and PLA fiber membranes through charge-mediated surface modification.","PeriodicalId":16881,"journal":{"name":"Journal of Polymer Engineering","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148672207","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its low mechanical strength makes it susceptible to deformation under the high vacuum pressures required during composite fabrication. To address this limitation, this study investigates the effects of polylactic acid (PLA), poly(vinyl alcohol) (PVA), and nano-sized silicon dioxide (SiO 2 ) as modifying additives, using blending and filling techniques to enhance the mechanical properties of PPC. The results show that all three additives improve the properties of PPC, with the formulation containing 7.5 wt% SiO 2 exhibiting the most significant enhancement. The tensile strength increased from 30.15 MPa to 40.63 MPa (a 34.76 % improvement), and the Young’s modulus increased from 393.05 MPa to 668.23 MPa (a 75.1 % increase). The onset decomposition temperature is 115.5 °C, and the fastest decomposition temperature is 159.3 °C. Microvascular composites were successfully fabricated using the vacuum-assisted resin transfer molding (VARTM) process combined with frontal polymerization. Under a vacuum pressure of −0.95 bar, the aspect ratio (AR) of the microvascular cross section improved from 1.67 ± 0.15 to 1.03 ± 0.01, confirming that the optimized, SiO 2 -reinforced PPC is suitable for use as a sacrificial template in high-pressure composite molding processes.","PeriodicalId":16881,"journal":{"name":"Journal of Polymer Engineering","volume":"46 1","pages":"58-69"},"PeriodicalIF":0.0,"publicationDate":"2025-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147911529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To improve the poor water resistance and lack of antibacterial activity of polyvinyl alcohol (PVA) films, series composites were prepared by using coumarin-3-carboxylic acid (CCA) grafted onto silica nanoparticles (CCAS) and then introduced into PVA matrix along with a plasticizer (PEG). The results showed that the maximum tensile strength of the composite film was increased by 94 %, while its good plasticity was preserved. As the CCAS content in the PVA matrix increased, the composite film presented raised water contact angle but decreased water vapor transmission coefficient, indicating an improvement in water resistance. However, excessive CCAS would affect the films from the aspects of opacity plus mechanical properties. In addition, the UV-shielding ability of the composite films was close to 100 %, which exerted an inhibitory effect on the growth of Escherichia coli ( E. coli ) and Staphylococcus aureus ( S. aureus ) (≥90 %). In particular, the inhibition rate against S. aureus was as high as 94 %. Compared with PVA film, the composite films exhibited superior mechanical properties, optical properties, antibacterial activity, and water vapor barrier properties, making them more promising for practical applications.","PeriodicalId":16881,"journal":{"name":"Journal of Polymer Engineering","volume":"46 1","pages":"46-57"},"PeriodicalIF":0.0,"publicationDate":"2025-11-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147906215","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study reported the fabrication of 180 nm MSNs featuring an ethane bridge skeleton structure, starting with the synthesis of MSNs, modifications were made by first applying γ -methacryloxypropyl trimethoxysilane (MPS) onto the MSNs. Following this, N-isopropyl acrylamide (NIPAM), acrylic acid (AA), and carboxymethyl chitosan (CTS) were grafted onto the MSNs, resulting in the successful creation of the composite MSNs-CTS-poly(NIPAM-co-AA) (abbreviated as MSNs-CTS-PNA) nano drug carrier. The experimental findings highlighted a notable drug encapsulation efficiency (75.5 ± 2.7 %) due to the core–shell architecture of MSNs-CTS-PNA. This tiered functionalization synergistically combines structural stability, pH and temperature stimuli-responsiveness, and biocompatibility. The ethane-bridged MSNs synthesis provides a rigid, porous framework for high drug loading, while CTS coating greatly boosts biocompatibility and prolongs circulation time. The optimized shell thickness balances high encapsulation efficiency and controlled drug release. These innovations make MSNs-CTS-PNA an advanced platform for targeted, combination, and environmentally adaptive drug delivery.","PeriodicalId":16881,"journal":{"name":"Journal of Polymer Engineering","volume":"45 10","pages":"816-827"},"PeriodicalIF":0.0,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147888864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional fluid loss additives often fail to deliver stable performance in these extreme environments, largely due to inadequate functional group composition and thermal stability. This work introduces an innovative strategy by regulating the structure of quaternary AM/AMPS/NVP/DMDAAC copolymers and clarifying their high-temperature filtration loss mechanisms. Five polymers with different compositions were synthesized, and their structural features, thermal stability, filtration loss performance, and mechanisms were systematically evaluated. The results showed that the monomer composition significantly influenced the polymer’s structural characteristics and thermal stability. Increasing the N-vinylpyrrolidone (NVP) content to 25–40 % enhanced intermolecular interactions and thermal stability at high temperatures, with a filtration volume of 25.7 mL in freshwater-based mud after aging at 240 °C. It was found that Poly D formed a dense filter cake through strong hydrogen bonding with high adsorption. Moreover, high dimethyldiallylammonium chloride (DMDAAC) content triggered charge shielding effect and disrupted bentonite dispersion. And NVP reduces permeability by modulating the equilibrium of filter cake affinity. This study reveals the structure-property relationship of copolymers under high-temperature and high-salt conditions, which provides new perspectives and experimental bases for designing and synthesizing high-temperature water-based fluid loss control agent for drilling fluids.","PeriodicalId":16881,"journal":{"name":"Journal of Polymer Engineering","volume":"45 10","pages":"871-881"},"PeriodicalIF":0.0,"publicationDate":"2025-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147911480","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it is difficult for the traditional circuit package substrate to realize both low dielectric and high thermal conductivity, resulting in high-quality signal transmission and fast heat dissipation cannot be achieved simultaneously. Here, for the first time, composite films (hBN/LCPs) with low dielectric constant in high-frequency and high thermal conductivity are prepared based on liquid crystal aromatic polyesters (LCPs) and hexagonal boron nitride (hBN). The highest thermal conductivity of hBN/LCPs film reaches 0.696 W m −1 K −1 , which is 3.3 times higher than that of the pristine LCPs. In the simulation of wafer heat dissipation, hBN/LCPs film shows a maximum surface temperature decrease of over 20 °C compared to the pristine LCPs, showing the fast heat transfer ability. The dielectric constants and dielectric losses of hBN/LCPs films keep the low values in the range of 0.4–1 GHz, being less than 3.4 and 0.007, respectively, meeting the requirements of 5G communication devices. Meanwhile, the hBN/LCPs films show good mechanical strength and heat resistance.

The system’s dynamic shear behavior was systematically investigated under small (5 mm) and large (15–25 mm) displacement regimes. Initially, isotropic MRSSG and anisotropic MRSSE were synthesized and characterized through rheological measurements, demonstrating that their storage modulus and damping factor exhibit autonomous frequency-dependent responses while being magnetically tunable. The bearing architecture employs a hierarchical design: the upper MRSSG unit operates through shear deformation to deliver stiffness and damping enhancement under small displacements, whereas the lower laminated MRSSE unit activates under large displacements to maintain structural stability. Dynamic testing revealed three critical control parameters governing shear performance: excitation frequency, applied current, and axial load. Notably, under a 15 mm displacement and 12.0 MPa axial load, the bearing achieved a maximum shear force output of 247.7 kN. Quantitative performance characterization was conducted through three key metrics: equivalent stiffness ( K h ), post-yield stiffness ( K d ), and equivalent damping ratio ( h eq ). While K h and K d showed positive correlations with frequency, current, and axial load, h eq demonstrated displacement-dependency, with optimal energy dissipation observed at smaller displacements.","PeriodicalId":16881,"journal":{"name":"Journal of Polymer Engineering","volume":"45 8","pages":"688-701"},"PeriodicalIF":0.0,"publicationDate":"2025-07-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147892343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At 0 % humidity, tensile strength of the film increased with concentration of CuS NP. Conversely, at 25 % and 50 % humidity, tensile strength initially increased and then decreased with rising CuS NP concentration, a behavior attributed to hydrogen bonding.

Through these advanced characterization approaches, we elucidated the precise influence of foaming agent H concentration on both the macroscopic performance and microstructural evolution of the foam composites. When increasing the foaming agent H content, the cellular morphology exhibited substantial expansion. This structural transformation was accompanied by a marked density reduction from 0.52 g/cm 3 to 0.18 g/cm 3 , concurrently driving a corresponding decline in tensile strength from 11.1 MPa to 4.3 MPa. Beyond these fundamental property variations, the composites manifested distinctive functional characteristics including notable shape memory effects and temperature-responsive oil absorption capabilities. Particularly noteworthy was the precisely tunable oil adsorption performance, which could be strategically modulated through controlled physical state transitions of the composites under thermal stimuli.
