Inspired by the internal structure of citrus fruit, soft conductive silicone foams are fabricated. The foams are made from a polydimethylsiloxane (PDMS) by mold casting using sugar templates. Addition of silicone oil and carbon black to the silicone allows creation of extremely soft foams that serve as resistive sensor. Completed by a pneumatic radial compression actuator (PRCA) surrounding the foams like a ring in analogy to citrus fruit peel, smart tunable dampers with sensing capabilities are demonstrated. The foams are evaluated for their electrical and mechanical properties alone as well as in conjunction with the PRCA. When pressurized, the PRCA radially compresses the smart foams, allowing to tune their stiffness and thus damping properties. Tunability of this system is evaluated by means of ball drop tests with respect to damping as well as the sensor performance regarding its sensitivity and stability. Overall, the study provides valuable insights into the behavior of conductive silicone foams and their potential as cushioning and impact sensing material.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"310 4","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202400273","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143831380","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}

Meanwhile, to some extent, there is a strong revival of various fibers from biopolymers regarding their utilization for various applications, based on their interesting structures, availability, sustainability, costs, and other factors. Regarding bioeconomy and sustainability, there has thus been an intensive market dynamic for biopolymers. Therefore, especially a variety of fiber materials have recently been described that are based on different biopolymers as, e.g., polysaccharides and biopolyesters. For this, a variety of enhanced polymer structure modification and sophisticated processing methods are applied. Instead of a complete and comprehensive overview (which would be beyond the scope of this Perspective format), the aim of this article is to elucidate some selected recent advantages in this field and to focus on the special features of these examples.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"310 4","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-01-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202400380","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143831490","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}

Synthesizing porous hydrogels through nanoemulsion templating represents a promising avenue for the development of advanced materials with tailored properties. Certain attributes, including but not limited to the ability to tune droplet size, volume fraction, and interdroplet interactions, provide tools to precisely manipulate the structure of nanoemulsions. The main research question is how the colloidal structure of the template changes the characteristics of a polymer network. Therefore, this study investigates the preparation of porous hydrogels using concentrated nanoemulsions as templates where modulating interdroplet interactions results in different pore structures and properties of the polymer network. Nanoemulsions are prepared by dispersing oil droplets in a continuous phase containing poly (ethylene glycol)-diacrylate (PEGDA) and sodium dodecyl sulfate (SDS). Subsequent photo-polymerization of PEGDA and removal of the oil phase leaves behind a porous polymer structure. Then, Hydrogels are analyzed to study the relationship between netwrok structures and water uptake capacities. The discussion focuses on how droplet arrangement under the influence of altered concentrations of SDS, provides confinement for changing the crosslink density of the polymer network.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"310 4","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202400359","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143831038","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}

After blending with diglycidyl ether of bisphenol A (DGEBA) and curing with tannic acid (TA), high performance, fire-retardant polymer networks are created. Near infrared spectroscopy (NIR) confirms the networks are highly cured and have low extractable content, while dynamic mechanical thermal analysis (DMTA) displays a lower Tg and heterogeneous network with increasing DOPO. The networks display a maximum improvement in flexural modulus, strength, and strain to failure of 20.6%, 55.5%, and 78.8% respectively, and at 65.4 MPa strength and 2.8 GPa modulus are comparable to high-performance networks. Thermogravimetric analysis (TGA) shows that increasing P reduces thermal stability, but contributes to higher char yield despite lower Si. The fire retardancy improve markedly measured via limiting oxygen index (LOI), increasing from 26.5% to a maximum of 35.5%, while V-0 behavior is readily achieved at the lowest DOPO content. Cone colorimetry further reduces peak heat release rate (PHHR) and total heat release rate (THHR) by 28% and 42%. This work presents hybrid bio-derived epoxy resins with excellent fire retardancy and good mechanical properties.","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"310 4","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202400342","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143831362","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}

A composite material (collagen/PGA/Na₂SiO₃) is used to create a scaffold with bone marrow mesenchymal stem cells (BM-MSCs) and human umbilical vein endothelial cells (HUVECs). MSCs maintained over 80% viability for 21 days on the scaffold. Calcium analysis shows increased calcium release in both control (3-fold, 2.7-fold) and osteogenic (2.3-fold, 2.5-fold) mediums on days 14 and 21. Gene expression analysis reveals higher levels of Osteopontin (OPN) (6-fold), Osteocalcin (OCN) (12-fold), and RUNX Family transcription factor 2 (RUNX2) (1.8-fold) in the osteogenic medium (p < 0.05). The impact of 5 µM temsirolimus treatment for 6 hours is assessed under control and dynamic culture conditions, reducing mammalian target of rapamycin (mTOR)-related protein levels (phospho (p)-mTOR and p-AKT) in CSCs. The composite material is characterized through viscosity and compression testing, confirming its suitability for supporting osteogenic differentiation and cell viability (WST-1, Alizarin Red Staining, Calcium Assay, RT-qPCR). Gene expression of CSCs, selected based on CD133 expression, shows elevated stemness-associated genes (OCT4, NANOG), EMT (MMP2, CXCR4, CDH1, CDH2), and drug resistance (ABCG1, ABCG2) in the CD133⁺ group in dynamic condition. Temsirolimus treatment reduces the expression of these genes by 21-fold to 7.52-fold (p < 0.05). These findings suggest temsirolimus as a promising therapeutic for CSC metastasis to bone.[Correction added on April 8, 2025, after first online publication: the word CHD is updated to CDH in this version.]","PeriodicalId":18151,"journal":{"name":"Macromolecular Materials and Engineering","volume":"310 4","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/mame.202400360","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143831386","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}
