Abstract

Abstract : A shape-memory polymer consisting of lignin and poly(ethylene carbonate) was obtained only by kneading without any toxic reagents. Abstract : In this article, we propose a thermally responsive shape-memory polymer (SMP) consisting of poly(ethylene carbonate) and non-deteriorated lignin nanoparticles. This SMP was obtained readily by thermal kneading and melt molding without requiring any chemical reaction. The shape-recovering properties of the SMP can be tuned by changing the feed ratio of the components. The estimation of viscoelastic, thermal and mechanical properties of the SMP reveals that the stepwise structural transitions in the SMP rendered a dynamic shape-recovering behavior.
