Patterning microscale pores into hydrogels provides an avenue for modifying the mechanical and transport properties of the whole gel while preserving the properties of its polymeric network. Modern methods of fabricating such pores, however, struggle with producing continuous networks of pores without sacrificing large volumes of the solid hydrogel. Here we apply a thermoresponsive microfiber patterning technique to produce networks of microcapillaries (serving as anisotropic pores) throughout the full-thickness of interpenetrating hydrogels (IPgels), thereby modifying the release of large drug-analogues from the gel. Using FRAP, we demonstrated that the diffusion of IgG and 10kDa Dextran were significantly hindered by the reinforced polymer network of the IPgel. It was found that the presence of microcapillary channels in IPgels increased the total payload delivered by more than 10% over the first 2 days of release. Release curves were modeled by first-order release kinetics, the Ritger-Peppas Power Law and the Weibull model, and describe drug-release behaviors that were dominated by diffusion. Microcapillary gels showed a 40% decrease in half-max time as compared to solid gels according to first-order approximations, and a 20% increase in timescale factor according to Weibull modeling. It is our goal to demonstrate a scalable and broadly applicable method of fabricating microcapillary networks in drug excipients, enabling the development of robust, drug-laden hydrogels with tunable transport properties.</p>","PeriodicalId":20382,"journal":{"name":"Polymers for Advanced Technologies","volume":"36 10","pages":""},"PeriodicalIF":3.8,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13290286/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148318835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fresh NR latex was incubated with urea and then processed through a series of centrifugation and redispersion steps at different forces to fractionate it into four low protein NR (LPNR) with average diameters of 238, 492, 721, and 1102 nm. Subsequently, graft copolymerization of styrene onto LPNR particles was carried out in the latex stage to prepare the NR with a polystyrene island‐nanomatrix structure. The relationship among particle size, morphology, and mechanical properties of the graft copolymer was analyzed. Transmission electron microscopy observations confirmed the formation of polystyrene island‐nanomatrix structure in each graft copolymer and revealed that the compactness of nanomatrix network increased as NR particle size decreased. The effect of nanomatrix network compactness on the mechanical properties was investigated through measurements of tensile properties, tear resistance properties, and viscoelastic properties, supported by digital image correlation strain mapping technology. A higher nanomatrix compactness was found to enhance mechanical properties and result in a more homogeneous distribution of strain.","PeriodicalId":20382,"journal":{"name":"Polymers for Advanced Technologies","volume":"36 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147332991","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 proposes an innovative high‐reflectivity CLC film based on the washing out/refilling strategy, where the polymerizable chiral dopant HCM006 is covalently anchored within the polymer network to stabilize its structure. Initially, a right‐handed polymer network (RH‐CLC) was engineered through UV polymerization, followed by the washing out of non‐crosslinked components and the subsequent infiltration of a left‐handed cholesteric system (LH‐CLC) doped with S5011. Secondary polymerization facilitated spectral overlap between the reproduced reflective band of the polymer network and the broadband reflection of the refilled system, forming an extended high‐reflectivity band. By optimizing the component ratios and polymerization conditions of the RH‐CLC/LH‐CLC systems, the reflection bandwidth was significantly broadened. Polarized light microscopy and ultraviolet–visible‐near‐infrared spectrophotometry confirmed that the film maintained a well‐aligned planar texture throughout the fabrication process while achieving high reflectivity. Furthermore, the regulation of the chiral dopant concentration gradient achieved broadband high‐reflectivity properties in the infrared region, enabling effective infrared shielding. The enhanced near‐infrared reflection effectively mitigates solar‐induced internal heat accumulation, rendering this film advantageous for thermal management applications, such as energy‐saving architectural coatings or adaptive smart windows.","PeriodicalId":20382,"journal":{"name":"Polymers for Advanced Technologies","volume":"36 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147921411","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}

An in situ composite emulsion system of polyacrylate/ethylene‐acrylic acid copolymer (PA/EAA) was therefore established by synchronously introducing EAA during emulsion polymerization and copolymerizing it with PA monomers, thereby mitigating phase separation inherent to physical blending and achieving close interfacial bonding that enhances emulsion stability and film‐formation properties. Experimental results indicated that composite latex particles exhibited a core–shell morphology, with EAA forming the shell and PA the core. ATR‐FTIR and acetone extraction confirmed hydrogen‐bonded associations and chain‐segment grafting between the two phases. DSC and TGA revealed that EAA significantly improved the thermal resistance of the composite films, and its bimodal thermal‐degradation profile demonstrated complementary thermal‐stability contributions from both phases. Incorporation of EAA markedly enhanced low‐temperature heat‐seal strength, reaching 3.13 N/15 mm at 80°C, although higher EAA contents increased Cobb values and reduced Kit oil resistance ratings. A comprehensive evaluation identified the 35 wt% EAA composite emulsion as achieving the optimal balance among water resistance, thermal stability, and heat‐sealability. Interface optimization and structural synergy afforded by the in situ composite process thus provide an effective route to develop water‐based EAA coatings with superior water resistance and thermal stability.","PeriodicalId":20382,"journal":{"name":"Polymers for Advanced Technologies","volume":"36 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147907136","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}

The highly exothermic reaction was often alleviated by adding unsaturated vinyl carboxylic acid monomers. In this investigation, poly(acrylonitrile‐co‐2‐carboxyethyl acrylate) P(AN‐co‐CEA) copolymers with varying contents of CEA monomers were synthesized. The effects of CEA on the thermal behavior and structural evolution of copolymers were systematically investigated by Fourier transform infrared spectroscopy (FTIR), X‐ray diffraction (XRD), differential scanning calorimetry (DSC), and thermal gravimetric analyzer (TGA). The results indicated that the introduction of CEA facilitated the cyclization reaction at lower temperatures through the ionic mechanism of the carboxyl group, broadened the exothermic peak, and reduced the heat release rate (Δ H /Δ T ). The activation energies (E a ) decreased from 157.7 KJ/mol for PAN homopolymer to 122.3 KJ/mol for P(AN‐co‐CEA) copolymer. Moreover, the CEA monomer promoted both the cyclization and dehydrogenation reactions, forming more stable cyclic structures and inhibiting the thermal decomposition of random chain segments. Consequently, higher carbon yield and a greater extent of stabilization (Es) were achieved. Additionally, the combined action of CEA and O 2 jointly enhanced the thermal oxidation stability process, resulting in the formation of oxygen‐containing structures and promoting the transition to a graphite‐like carbon network. Among the copolymers studied, the composition containing 2 wt% CEA exhibited the most favorable balance in the development of a well‐stabilized structure. It was found that the CEA comonomer has the ability to promote the thermal oxidation stabilization process, alleviate the highly exothermic reactions, and reduce the heat release rate. Hence, these findings suggest that P(AN‐co‐CEA) copolymers have the potential to become carbon fiber precursor materials.","PeriodicalId":20382,"journal":{"name":"Polymers for Advanced Technologies","volume":"36 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147895711","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, enhancing the mechanical/thermomechanical properties while improving the toughness of the epoxy thermosets remains a challenge. Herein, a new hyperbranched epoxy resin containing a flexible siloxane skeleton (HBPSER) was synthesized for improving the comprehensive performance of epoxy thermosets. Specifically, the phenolic hydroxyl‐terminated hyperbranched precursor (HBPS) was first synthesized using 1,3‐bis(chloromethyl)‐1,1,3,3‐tetramethyldisiloxane (A 2 ‐type monomer) and 3,5‐dihydroxybenzoic acid (CB 2 ‐type monomer), followed by the surface modification with epichlorohydrin to afford the HBPSER.

This process enabled the chemical grafting of vinyl functional groups onto EG, yielding vinyl‐functionalized expandable graphite (Vi‐EG). The introduced vinyl groups served as crosslinking sites, allowing Vi‐EG to chemically bond with silicone rubber (SR) via block copolymerization, thereby enhancing interfacial adhesion and dispersion within the SR matrix. The successful grafting modification was confirmed by Fourier‐transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM/EDS). Vi‐EG was then physically blended with silicon carbide (SiC) and zirconia (ZrO 2 ) as flame‐retardant additives into a room‐temperature vulcanized (RTV) SR matrix to construct an efficient multiphase flame‐retardant system. SiC and ZrO 2 , as high‐melting‐point ceramic fillers, synergistically worked with Vi‐EG to promote the formation of thermally stable and compact char layers, which effectively suppressed heat transfer and oxygen ingress. In addition, SiC contributed to the mechanical reinforcement of the composite due to its inherent rigidity and good compatibility with the SR matrix. Meanwhile, ZrO 2 also played a positive role in improving the thermal stability of the composite system. The optimized formulation (SR: Vi‐EG: SiC: ZrO 2 = 100:8:3:2.5) exhibited a high limiting oxygen index (LOI) of 37.1 vol.%, representing a 67.11% increase compared to pristine SR, and achieved a UL‐94 V‐0 rating. The composite demonstrated excellent thermal stability, with a char yield of 59.53 wt.% at 900°C (R 900 ), an 18.32% improvement over pristine SR. Cone calorimetry results revealed a peak heat release rate (PHRR) of 138.3 kW/m 2 , total heat release (THR) of 13.0 MJ/m 2 , and total smoke production (TSP) of 3.2 m 2 , all significantly reduced compared to the pristine matrix. Importantly, while maintaining high flame retardancy, the composite retained favorable mechanical properties, including a tensile strength of 1.863 MPa, an elongation at break of 349.4%, a tear strength of 8.917 kN/m, and a compressive modulus of 6.158 MPa under 50% compressive strain.
