Title: Shape memory polymer blend materials

Abstract

An object comprising: a blend of (i) a phenol-containing polymer and (ii) a nitrile butadiene rubber; wherein the phenol-containing polymer is present in an amount of at least 5 wt % and up to about 95 wt % by total weight of components (i) and (ii). The object may further contain an electrically conducting component dispersed within the blend or on a surface of the blend. Also described is a method of thermal-activated reversible mechanical deformation of the object by (i) deforming the object at a first temperature, which is at or above the glass transition temperature of the object, and applying a stress on the object; (ii) fixing the deformed state by cooling the object to a second temperature of no more than 0° C. while under stress, and removing the stress; and (iii) recovering the object to the original shape by raising the temperature of the object to the first temperature.
