Characteristics of Self-Healable Copolymers of Styrene and Eugenol Terminated Polyurethane Prepolymer
With limited biomass that can be currently utilized as a renewable resource, it is important to develop a method to convert biomass into materials that can replace fossil fuel product. In this paper, eugenol, a bio-based allyl chain-substituted guaiacol, was used to synthesize self-healable copolyme...
