Article Abstract
With growing awareness of environmental protection and an increasing emphasis on sustainable development, bio-based epoxy resins have garnered significant attention due to their outstanding performance and eco-friendly characteristics. However, their inherent flammability restricts their broader application. Consequently, the development of efficient and environmentally benign flame-retardant technologies for bio-based epoxy resins is critical to advancing high-performance applications and fostering the development of sustainable materials. The four primary methods to enhance the flame retardancy were introduced, including molecular structure design, physical additives, reactive flame retardants, and flame-retardant coatings. This paper reviews the current flame-retardant technologies and research progress related to bio-based epoxy resins. Furthermore, the existing challenges and solution measures of bio-based epoxy resins in industrial application are analyzed, and cost-effectiveness, environmental impact, and life cycle assessment needs more attention. This study provides new insights into the design and application of flame-retardant bio-based epoxy resins.

A one-pot strategy was developed to fabricate a strong and ductile elastomer composed of chitin nanocrystals and poly(deep eutectic solvent) (ChNC/PDES), based on a dual-network structure formed through glycidyl methacrylate (GMA)associated modification, polymerization and crosslinking. This approach enables the integrated pretreatment, chemical modification, and nanodispersion of chitin within a lactic acid/choline chloride deep eutectic solvent (DES) system. Whereafter, the ultraviolet initiated polymerization of GMA with ChNC and DES components produced a homogeneous elastomer with a maximum tensile strength of 4.

This systematic literature review explores recent advancements in polymer-based composite materials designed for thermal insulation in automotive applications, with a particular focus on sustainability, performance optimization, and scalability. The methodology follows PRISMA 2020 guidelines and includes a comprehensive bibliometric and thematic analysis of 229 peer-reviewed articles published over the past 15 years across major databases (Scopus, Web of Science, ScienceDirect, MDPI). The findings are structured around four central research questions addressing (1) the functional role of insulation in automotive systems; (2) criteria for selecting suitable polymer systems; (3) optimization strategies involving nanostructuring, self-healing, and additive manufacturing; and (4) future research directions involving smart polymers, bioinspired architectures, and AI-driven design.

A new intrinsically flame-retardant starch-based epoxy resin (OS-DDM-EP) was successfully fabricated from a green and facile process using resource-rich and low-cost starch as raw materials. The molecule structure of OS-DDM-EP was verified by infrared spectrum and nuclear magnetic resonance. TGA results revealed a much higher than residual char rate for OS-DDM-EP/DDM (22.
