PHOTO-TAILORED SHAPE MEMORY ARTICLE, METHOD, AND COMPOSITION

摘要

A method of forming a photo-tailored shape memory article is described. The method includes forming an article that includes a photochemically crosslinkable polymer composition, illuminating at least two different regions of the article with different light exposures to form first and second crosslinked polymer compositions with different shape memory critical temperatures. Also described are photochemically crosslinkable polymer compositions that include a di(meth)acrylate macromer, a multifunctional thiol, and a photoinitiator.
