Special Issue Information

Dear Colleagues,

Epoxy-based polymeric materials are utilized extensively in various fields such as aerospace, automotives, energy, and electronics, as well as in building materials, due to their exceptional mechanical and electrical insulation, bonding capabilities, and chemical resistance. Currently, there is growing interest in developing high-performance epoxy polymers and composites that are environmentally sustainable; however, challenges remain, including the low toughness of conventional epoxy resins. We lack a systematic understanding of the properties of cross-linked networks, which limits our low-cost approaches to producing resins and their composites and leads to the inferior performance of new environmentally friendly epoxy resins compared to traditional ones, as well as degradation issues and recovery concerns. Therefore, it is crucial to explore innovative technologies for developing advanced epoxy-based polymeric materials that meet the requirements of these fields.

This Special Issue will publish studies related to epoxy-based polymeric materials that focus on the following areas:

(1) Investigations into the structural design, synthesis, molecular characterization, polymerization mechanisms, and properties of epoxy resins.
(2) Composite materials as advanced hardeners, modifiers, and accelerators of high-performance resin matrices.
(3) The synthesis, characterization, processing, and application of epoxy resin adhesives and coatings.
(4) The curing kinetics and mechanisms of different epoxy resin/curing agent systems, analyzed by combining molecular simulation and chemical calculation methods.
(5) Research on the properties and applications of green, recyclable, self-healing epoxy resin materials.

This Special Issue also recommends that authors investigate the fundamental molecular mechanisms of newly developed epoxy resin materials based on their properties to provide researchers with molecular design principles.

This study investigates the development of epoxy–resin composites reinforced with coral-derived calcium carbonate (CaCO3) fillers for enhanced radiation shielding and mechanical properties. Leveraging the high calcium content and density of coral, composites were prepared with filler weight fractions of 0%, 25%, and 50%. SEM and EDS analyses revealed that higher filler concentrations (50%) increased particle agglomeration, affecting matrix uniformity. Mechanical testing showed that while the tensile and flexural strengths decreased with the increased filler content, the compressive strength significantly improved, reaching 135 MPa at a 50% coral content. Radiation shielding evaluations demonstrated enhanced attenuation with a higher filler content, achieving 39.63% absorption at 60 kVp for the 50% coral composite. However, the shielding efficiency was notably lower compared to lead, which achieves over 99% absorption at similar energy levels. These quantitative comparisons highlight the material’s limitations in high-radiation environments but emphasize its suitability for moderate shielding applications. Despite their lower shielding efficiency, the composites provide an environmentally friendly and non-toxic alternative to lead, aligning with sustainability goals. Future work should focus on optimizing filler dispersion, mitigating agglomeration, and exploring hybrid systems to enhance the shielding efficiency and mechanical properties. The further quantitative evaluation of parameters such as Zeff and cross-sections is recommended to comprehensively assess the material’s performance. Full article
