摘要：

Most shape memory polymers are rigid and exhibit only one way (irreversible) shape memory effect. This work explored the two-way (reversible) shape memory effect for semi-crystalline elastomeric networks. These semi-crystalline networks with various gel fractions and crosslinking densities were synthesized via radical initiated crosslinking of poly(ethylene-co-vinyl acetate). The thermal, mechanical, and the two-way shape memory properties of the resulting materials were investigated. The critical impact of the gel fraction on the two-way shape memory behaviors was revealed. The results from this study establish the basis for potential applications involving soft reversible actuation. (C) 2011 Elsevier Ltd. All rights reserved.
