Abstract:
Liquid crystalline network compositions comprising azo-containing aromatic epoxy units cross-linked with alkylene diacid units having alkylene segments containing at least one methylene unit, wherein the azo-containing aromatic epoxy units and alkylene diacid units are connected by ester linkages resulting from ring-opening esterification between the epoxy units and alkylene diacids, and wherein the azo-containing aromatic epoxy units and alkylene diacid units are in a molar ratio that results in the liquid crystalline network composition exhibiting a glass transition temperature (Tg) of at least 25° C. Methods for producing these compositions and their use in light- or thermal-activated physical deformation, shape memory applications, and self-healing, as well as their ability to be recycled and used in additive manufacturing processes are also described.
