Bisphenol A-based epoxy resins are widely used due to their excellent mechanical and thermal properties, but their permanently crosslinked thermoset structures limit recyclability after use. In this study, a bisphenol A-based epoxy resin containing chemically cleavable bonds was designed and synthesized to enable controlled chemical recycling. The curing behavior with appropriate curing agents was investigated, and the resulting thermosets were evaluated in terms of thermal and mechanical properties. In addition, the applicability of the developed epoxy system to composite materials and its chemical depolymerization behavior for raw material recovery were examined. The results demonstrate the potential of a high-performance, chemically recyclable epoxy resin suitable for composite applications.
