The physical characteristics of the polymer–filler composites are influenced by intrinsic polymer structure (e.g., molecular weight, crystallinity, crosslinking) and external conditions (e.g., temperature, loading rate, and aging). Structural, physical and chemical characterization were performed. Various mixture ratios and processing conditions were investigated for both epoxy resin- and cement-based matrices. Results indicate that MNPs provided superior interfacial bonding and structural performance compared with other fillers, such as coconut shell and sawdust, particularly in epoxy resin systems, where improved adhesion and workability were observed. However, incorporating cellulosic fillers reduced stress and stiffness in epoxy-based composites. Interfacial strength was found significantly weaker among MNP and cement-based matrix. These findings demonstrate the potential of MNPs as an environmentally friendly filler, offering a viable pathway toward sustainable polymer composite development.</div></div>","PeriodicalId":101087,"journal":{"name":"Results in Materials","volume":"29 ","pages":"Article 100923"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147448759","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to develop and systematically evaluate a multifunctional chitosan–gelatin (CS–Gel) nanocomposite hydrogel capable of simultaneously addressing these limitations through a tri-modal reinforcement strategy.
