The present disclosure provides an epoxy resin cured product, which is obtained by performing the curing reaction between an epoxy resin curing agent and an epoxy resin, and a dynamic bond and a non-dynamic bond are generated. Accordingly, the dynamic bond and the non-dynamic bond generated simultaneously by the reaction between the epoxy resin curing agent and the epoxy resin can make the epoxy resin cured product recyclable and reprocessable while also having the certain thermal and mechanical properties. |
