On the other hand, nonbiodegradable polymeric materials increase issues related to their disposal and the generation of hazardous microplastics. Hence, this research aims to develop a nanofibrous membrane filter composed of polyvinyl alcohol (PVA) as a biodegradable polymer, and boric acid (BA) using an electrospinning technique. This study investigates the effect of BA on fire behavior, mechanical properties, and filtration performance of the nanofiber membranes. The morphological results show that the samples containing BA have no beads on the nanofibers. Incorporating boric acid into PVA membranes can reduce peak release heat by ≈39%. Additionally, the nanofibers containing BA can offer enhanced mechanical properties of tensile strain (≈3.6%) and Young's modulus (up to ≈45%). The optimized BA/PVA nanofibers can also demonstrate superior filtration efficiency (above 99.9% for 300 nm particles) and a low-pressure drop (150 Pa at 5.3 cm s−1 airflow velocity). Therefore, PVA nanofibers containing BA can improve not only the fire behavior than those of pure PVA nanofibers, but also increase mechanical properties, and filtration performance.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"310 8","pages":""},"PeriodicalIF":4.6,"publicationDate":"2025-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202500017","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144869197","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, the focus is on optimizing MXene-incorporated electrospun fibers and subsequent characterizations to assess their potential for biomedical applications. Polyvinyl alcohol (PVA) is used as the appropriate matrix material and process parameters are finetuned to ensure effective incorporation of MXene. XRD and spectroscopic analysis confirm the successful synthesis and integration of MXenes into the nanofibers. Morphological analysis shows that MXene led to the formation of sub-micrometer fibers with smooth surfaces and reduced the fiber diameter (587 ± 191 nm) compared to pure PVA (696 ±160 nm). Investigations on the electrical characteristics demonstrate a fourfold increase in conductivity of nanofibers (σ = 1.90 ± 0.45 × 10−8 S cm−1) after MXene addition (compared to σ = 0.46 ± 0.05 × 10−8 S cm−1 of PVA-only fibers). Furthermore, the MXene-PVA system demonstrates a nearly twofold increase in mechanical stiffness, with E = 136.87 ± 19.63 MPa than 71.42 ± 16.56 MPa for PVA. Moreover, the initial in vitro experiments indicate improved L929 cell viability. These findings position MXene-PVA composites as a highly versatile platform for advanced biomedical devices, such as electroactive tissue scaffolds and wearable sensors.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"310 7","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-03-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202400433","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144647009","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is related to the ability to undergo physical or chemical changes in response to external stimuli. Among them, photothermal responsive materials have attracted great interest. This study focuses on the development of a multilayer system (MS) consisting of benzophenone-modified polydimethylsiloxane (PDMS) ring and a thermo-responsive core made of poly(N-isopropylacrylamide-co-N-isopropylomethacrylamide) (P(NIPAAm-co-NIPMAAm)), gelatin, and gelatin methacrylate (GelMA). The system utilizes the thermal sensitivity of P(NIPAAm-co-NIPMAAm) and the photothermal effect of gold nanorods (AuNRs) to achieve an on-demand controlled release mechanism within 6 min of near-infrared (NIR) light irradiation. The mechanical properties investigated in the compression test show significant improvement in MS, reaching 60 times greater value than the material without a PDMS ring. In addition, NIR irradiation for 15 min activated the antimicrobial properties, eliminating 99.9% of E. Coli and 100% of S. Aureus, thus presenting pathogen eradication. This platform provides a versatile methodology for developing next-generation smart materials, advanced delivery mechanisms, and multifunctional nanostructured composites. This work highlights the potential of photosensitive materials to revolutionize the field of soft robotics, optics and actuators, and on-demand systems by providing precise control over release dynamics and improved material properties.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"310 7","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202400462","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144647021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, sound absorption properties of fused filament fabrication (FFF) 3D printed parts with FG porous structure and controlled pore sizes are investigated. For this purpose, samples with single porosity with infill densities of 40% to 90% are first printed to compare with the absorption coefficient of FG porous samples. FG porous samples are also printed as unified structures in two groups of FG porosity 40/50/60% and 70/80/90%. Sound absorption coefficient is tested using the transfer function method and impedance tube sound absorption test system. The experimental results of single porosity samples show that at higher frequencies, samples with lower infill density (higher porosity) have higher sound absorption coefficients, while at lower frequencies, samples with higher infill density (lower porosity) have more effective sound absorption. Unlike uniform porous structures at lower frequencies, FG porous structure provides higher sound absorption without increasing thickness and weight. In addition, it is found that the orientation of samples with the FG porous structure has a different behavior of the sound absorption coefficient.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"310 7","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202400450","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144646985","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focuses on fabricating doxorubicin-loaded, non-porous POEGMEMA (Poly(oligo(ethylene glycol) methyl ether methacrylate)) and PLGA (Poly(D,L-lactide-co-glycolide))/POEGMEMA scaffolds for locoregional chemotherapy. Polymer synthesis, hydrogel formation, and drug-loading processes are performed using a one-pot approach. The scaffolds were characterized by mechanical, swelling, degradation, and release tests. 10% PLGA content, causes PLGA/POEGMEMA scaffolds to give a 2.5 times lower swelling ratio and sixfold higher compression stress than POEGMEMA scaffolds. Also, PLGA addition causes an increase in the biodegradation half-life of POEGMEMA-based hydrogel scaffolds. While PLGA/POEGMEMA scaffolds exhibit a degradation-dependent release profile, POEGMEMA scaffolds give a burst release due to their high water uptake ratio. The burst release behavior of POEGMEMA scaffolds causes a high antiproliferative effect (viable cells: 5–10%) against HT-29 and MCF-7 cancer cells in the short term. In contrast, the controlled and sustained release profile of PLGA/POEGMEMA scaffolds shows an antiproliferative effect (viable cells: 50–60%) dependent on the release ratio. This hydrogel scaffold platform allows tuning physical and functional properties to deal with diverse physiological conditions at the region after tumor surgery for locoregional chemotherapy.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"310 7","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202500002","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144646986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
