摘要

The present invention discloses the fabrication and application of a shape memory polymer possessing transesterification-induced permanent reshaping. The ester-containing crosslinked polymer is obtained by crosslinking ester bearing polymer precursors or by reaction of monomers which yield ester bonds. The transition temperature falls between 20-150° C. The reshaping temperature is tuned by catalyst amount and should be 20° C. above the transition temperature. The breakthrough of the present invention lies in integrating shape memory effect and plastic deformation into the same polymer and triggering the respective function at different occasions. The permanent shape of as synthesized polymer could be modified arbitrarily and cumulatively. Therefore, the hierarchical structure which could not otherwise be obtained due to the limit of mold fabrication process should expand the practical application of SMPs.
