Herein, lithium nitrate trihydrate (LNH), one of the particularly promising low-temperature salt hydrate PCMs, was encapsulated with three-dimensional (3D) gelatin/polyvinyl alcohol (PVA) cross-linking networks to fabricate flexible, stretchable, and form-stable phase change salogels. Specifically, the salogels were fabricated by dissolving macromolecular gelatin and PVA in melted LNH and then cross-linked using 1,4-butanediol diglycidyl ether (BDDE). The encapsulation using a 3D cross-linked polymer network can effectively solve the problems of melting leakage/flowing and water-loss drying/hygroscopic deliquescence of LNH. The results showed that the gelatin/PVA/LNH salogels exhibit good form stability, high latent heat (~170.9 J g−1), and excellent hygroscopic properties with the saturation water absorption of dry gels up to 1.730 g g−1. Meanwhile, the gelatin/PVA/LNH salogels show good mechanical properties, and their elongation at break could reach 1086%. Therefore, these hygroscopic phase change salogels are expected to be applicable in wearable devices for human low-temperature thermal and humidity management.\u0000 </div>","PeriodicalId":183,"journal":{"name":"Journal of Applied Polymer Science","volume":"142 28","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144281535","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}

However, problems including low mechanical strength, poor chemical stability, and excessive usage of hazardous solvents limit their application in the industry. The use of nanofillers has been shown to be a tactic for improving ethyl cellulose's functioning to overcome these problems. In this study, nano-sized aqueous dispersions of nitrocellulose (NC) with different nitrogen contents (13.1%, 12.6%, and 11.7%) were created using a solvent replacement technique that can eliminate organic solvents. The shape, chemical structure, thermal characteristics, moisture absorption, and mechanical performance of the composite films were all thoroughly examined utilizing SEM, FTIR, DSC, TGA, dynamic vapor sorption, and a universal testing apparatus. The activation energy of S-NC(B)-8 wt% was twice than the EC film, suggesting that the thermal disintegration temperature of the EC-NC composite films was raised. The samples' mass loss was less than 6% following a 24-h soak in water, indicating strong water resistance. The tensile strength of the EC-NC composite films increased by up to 77% when compared to the EC film, which showed that the insertion of NC nanoparticles greatly increased the mechanical strength of the films.\u0000 </div>","PeriodicalId":183,"journal":{"name":"Journal of Applied Polymer Science","volume":"142 28","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144281562","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}

The different nucleating agents are added at a fixed content to PHB by melt compounding. The crystallization process is studied by DSC and the crystalline morphology by polarized optical microscopy. Mechanical performance is studied both by tensile and impact tests. Disintegration in compost, which represents the first step of the biodegradation process, is also performed. As a result, the nucleating efficiency of the different additives is evaluated, demonstrating how a more effective nucleating process is related to better mechanical properties.

The study investigated the effects of different contents of MBATP on the curing behavior, flame-retardant effect, thermal stability, combustion characteristics, mechanical properties, and transparency of FREPs. The study revealed that the introduction of MBATP led to a decrease in the maximum decomposition rate while simultaneously facilitating the early decomposition of epoxy resin (EP). The FREP-4 (4 wt% MBATP) attained a V-0 rating through the UL-94 standard, accompanied by an oxygen index of 33.5%. Furthermore, total smoke, the peak heat release rate, and total heat release emission of FREP-4 were diminished by 26.1%, 67.4%, and 25.5%, respectively, compared with EP. Residual carbon and volatile gas emissions tests showed that MBATP effectively contributed to flame retardancy in both the condensed phase and gas phase.

Treatment methods such as bypass graft operations, while often successful, can fail in cases of systemic disease or compliance mismatch. Tissue engineered vascular grafts may offer a potential solution, by means of an implantable cell-seeded scaffold that can integrate into the graft site. Modifications to the cell culture environment, such as through physical modification of the scaffold structure, or culturing cells in a dynamic fluidic environment, have been shown to alter cellular behavior. Herein, we combine these two approaches by incorporating electrospun polycaprolactone scaffolds consisting of smooth and modified fiber surface topographies within a series of novel 3D printed microfluidic bioreactors. The bioreactors successfully maintained the viability of human umbilical vein endothelial cells over a 24-h period, with the smooth scaffolds in static culture and dimpled scaffolds under dynamic culture indicating the highest cell viability. An increase in stiffness and hydrophilicity of the modified scaffold is also noted in comparison to the scaffold consisting of smooth fibers. These results indicate that both the bioreactor system and the modified electrospun scaffold are capable of inducing variations in cellular response, thus warranting further investigation for the advancement of vascular tissue engineering.","PeriodicalId":183,"journal":{"name":"Journal of Applied Polymer Science","volume":"142 25","pages":""},"PeriodicalIF":2.7,"publicationDate":"2025-04-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/app.57062","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144100853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
