Shape memory polymers moisture-active

The most studied SMPs are thermally activated. This means that the shape recovery is triggered by heating the polymer to a temperature above its switching temperature. Marty researchers have achieved the SME on conventionally thermally-active SMPs. Employing hydrophilic or water solirble ingredients in SMPs can accelerate the moisture/water-active shape recovery process. Chen et al. (2007a) developed a water-active shape memory biodegradable polymer from chitosan cross-linked with epoxy. The chitosan is relatively hydrophilic. [Pg.7]
