Study on Preparation and Properties for Epoxy Shape Memory Polymer

Abstract:

A thermosetting epoxy shape memory polymer was obtained by adding modifier end thioglycolic acid butyl glycol ester which prepared in our lab into E-44/D-230. The results show that the tensile and impact strength of modified epoxy are improved, and it can be bended as U style in thermal transition temperature, shape fixed rate is 100% after removing external force. When temperature is raised to thermal transition temperature again, the shape of modified epoxy can be restored completely. The time of recovery is between 178~183s and not effected by cycle times.
