Additionally, the SBS PTFE–SiO2 membrane exhibited a high porosity of 83% compared to 55% in the commercial PTFE membrane. When used for membrane-assisted extraction, the PTFE–SiO2 membrane exhibited a higher caffeine transport rate (3.84 × 10−7 m s−1) than the commercial PTFE membrane (2.18 × 10−7 m s−1). The addition of SiO2 nanoparticles provided better hydrophobicity and higher phase stability during membrane-assisted solvent extraction. Given the excellent thermal and chemical stability of PTFE–SiO2, this type of membrane shows potential for high-value solvent extraction and stable long-term operation with no emulsion generation.

The nanocomposites elaborated in this study, based on silver nanowires dispersed in a polyurethane matrix, were obtained via a one-step spray coating process on a flexible PET substrate. A polyol-based synthesis combined with a nanowire screening process allows for the selection of nanowires with a very high aspect ratio (400). These high aspect ratio wires enable the conductive composite coatings (pc = 1.3 vol.%) with a transmittance close to 70%. The confinement of high aspect ratio nanowires in a very thin composite layer facilitates a comparison between the increase in mechanical modulus and predictive behavior models for fiber-reinforced laminates. The mechanical reinforcement aspect ratio found by extrapolation exhibits the key role of the longest nanowires in mechanical properties. A homogenization limit has been identified at approximately 2.5 vol.% for this type of composite.

However, the typical EOR polymer, high-molecular-weight (MW) partially hydrolyzed polyacrylamide (HPAM), often encounters injectivity challenges, particularly in low permeability reservoirs, which is attributed to the lack of a quantitative matching relationship of sizes between polymer and porous media. In this study, the radius of gyration (R\u0000 g) and the hydrodynamic radius (R\u0000 h) of five HPAMs with various MW ranging from 4.8 × 106 to 15.4 × 106 g·mol−1 were determined via light scattering. Subsequently, by employing polycarbonate nuclepore membranes to mimic regular micro- and nano-pore throats, the flow and matching relationship of these HPAM solutions in porous media were investigated. It was found that the R\u0000 g of HPAM gradually magnifies from 89 to 161 nm with an increase in polymer MW, while R\u0000 h ranges from 53 to 92 nm. The matching relationship between R\u0000 g/R\u0000 h and nuclepore size (R\u0000 p) can be described as follows: when R\u0000 p/R\u0000 g < 2.01 or R\u0000 p/R\u0000 h < 3.7, injection difficulties emerge for HPAM solution; conversely, when R\u0000 p/R\u0000 g > 2.48 or R\u0000 p/R\u0000 h > 4.77, there is no blockage caused by the HPAM solution.\u0000 </div>","PeriodicalId":183,"journal":{"name":"Journal of Applied Polymer Science","volume":"142 22","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143892839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

PANI was in situ synthesized on the surface of h-BN sheets, resolving the inherent stacking nature of h-BN and agglomeration of PANI, and then incorporated into a PDMS coating.

One of the most promising approaches for reducing interfacial fatigue damage under the long-term repetitive effects of environmental and train loads is the incorporation of organic polymer latex into SCC. In this study, the fatigue behavior and damage modeling of the track slab-SCC interface (TS-SCC0) and track slab-polymer-modified SCC interface (TS-SCC20) were investigated through three-point bending tests. The results demonstrated that most of the TS-SCC0 and TS-SCC20 interfaces failed in the mode of mortar failure, that is, a thin layer of mortar attaching to the TS side. The proportion of aggregate-mortar debonding failure reduced from 4.09% to 1.86% upon the incorporation of polymer latex, suggesting that the polymer latex contributed to the enhancement of the bonding strength within the mortar-aggregate transition zone. The average fatigue life of TS-SCC20 was 2.27–3.52 times longer than that of TS-SCC0 under the same stress level. The evolution of interface strain was divided into three stages: rapid growth, stable growth, and instability. The proportion of the third stage in TS-SCC20 was 1.67 times higher than that in TS-SCC0, indicating the hindrance of polymer to crack propagation. Moreover, a generalized interfacial fatigue damage model linking the damage index to the fatigue life ratio at various stress levels was established to quantitatively study the fatigue damage process of the TS-SCC20 interface and to serve as an interfacial fatigue constitutive model in finite element analysis.\u0000 </div>","PeriodicalId":183,"journal":{"name":"Journal of Applied Polymer Science","volume":"142 22","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-03-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143892836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to propose an external power-free wound healing dressing with electrical stimulation function, polyvinylidene fluoride (PVDF) nanofibers incorporating graphene oxide (GO) at varying concentrations were fabricated via electrospinning technique. Scanning electron microscopy (SEM) was employed to reveal the morphology of the composite nanofibers. Fourier transform infrared (FTIR) spectroscopy and X-ray diffraction (XRD) analyses confirmed the transition of PVDF from α phase to β phase. The antibacterial efficacy of PVDF/GO composite nanofibers against \u0000 Staphylococcus aureus\u0000 was rigorously examined. Results indicated a marked enhancement in antibacterial efficacy in correlation with the increasing content of GO. Moreover, piezoelectric property assessments, cytotoxicity, and hemolysis tests were meticulously performed. The outcomes suggested that nanofibers containing 0.5 w/w% GO (PVDF/GO-0.5) demonstrated superior performance across all evaluated metrics, particularly in terms of mechanical properties, piezoelectric characteristics, and antibacterial efficacy. These findings imply that PVDF/GO-0.5 nanofibers possess the capability to mimic the endogenous electric field, which is beneficial to boost cellular migration and proliferation, thereby accelerating the wound healing process.
