CHEMICALLY DEGRADABLE EPOXY COMPOUND, METHOD OF PREPARING SAME COMPOUND, EPOXY COMPOSITE MATERIAL CONTAINING SAME COMPOUND, AND METHOD OF DEGRADING SAME COMPOSITE MATERIAL
Proposed is a recyclable epoxy compound containing an α,β-unsaturated ketone group and/or a hydroxy ketone group bonded through an aldol reaction between a ketone group and an aldehyde group containing a hydroxyl group among non-toxic natural materials, without using a bisphenol A type epoxy, a toxic material. In addition, proposed are a method of preparing the same compound, an epoxy composite material containing the same compound, and a method of degrading the same composite material.
