A waterborne shape memory polymer coating that gives textiles and fibers good shape memory performance. An amphiphilic, crosslinkable grafted polysaccharide polymer was synthesized and provided in a water dispersion that can be applied to a flexible fibrous material and then crosslinked to yield good shape memory properties. The polymer coating showed good binding to human hair, which could be styled into a permanent shape (e.g., straight) during the crosslinked step. Next, this permanent shape can be styled to a temporary shape (e.g. curly) by heating and styling, and cooling. Finally, the permanent style can be regained by activation with water, heat, or both.

Amphiphilic graft copolymer for waterborne shape memory coatings

A multi-block thermoplastic polyurethanes system which incorporates polyhedral oligomeric silsesquioxane into conventional biodegradable thermoplastic polyurethanes built up by poly(&#x3b5;-caproactone) and polyethylene glycol blocks, resulting in biostability. The multi-block thermoplastic polyurethanes are synthesized from lysine-diisocyanate with poly(&#x3b5;-caprolactone)-diol, polyhedral oligomeric silsesquioxane-diol, and poly(ethylene glycol) using a one-step synthesis process.
