Eugenol‐Derived Siloxane Epoxy Toughener for High‐Performance Diglycidyl Ether of Bisphenol A and Basalt Fiber Composites
Epoxy resins combine high stiffness, thermal resistance, and processability but remain constrained by intrinsic brittleness. Here, a siloxane‐containing bio‐based epoxy toughener, EPMOPTSi, was synthesized from eugenol through hydrosilylation followed by epoxidation and employed to modify commercial diglycidyl ethe...
