Abstract:
A humidity responsive material having shape memory comprising:at least one shape deformable matrix material comprising an elastomeric polymer and a non-elastomeric polymer; wherein the humidity responsive material is capable of being deformed in at least one spatial dimension when exposed to one or more external forces, is capable of maintaining a degree of deformation in at least one spatial dimension once the external force is removed, and is capable of exhibiting a change, or percent recovery, in at least one spatial dimension when subjected to a humid environment; wherein the percent recovery is greater than about 60% when subjected to a humid environment; wherein the humid environment has a relative humidity of at least 50%; wherein the humidity responsive material exhibits a temperature change of less than about 15Â° C. when subjected to the humid environment.
