Paper Title:
Preparation and Investigation on Properties of Shape Memory Epoxy Modified by Hyperbranched Polyester
  Abstract

A series of hyperbranched polyester (HBPE) modified shape memory epoxies (SMEPs) were prepared for the first time. The materials’ toughness, mechanical properties and heat resistance were investigated by impact test, tensile test and DSC analysis. Besides, the possible effect of hyperbranched structure on SMEP’s shape memory property was studied by fold-deploy shape memory test. The results showed 5wt. % HBPE modified SMEP had the optimum properties. Its impact strength, tensile strength and elongation at break were increased by 51.8, 11.4 and 25.4%, respectively, without negative effect on SMEP’s heat resistance and shape memory property. All the samples had high shape retention ratio and 100% shape recovery ratio.
