Hydrogel with Unidirectional Alignment of Lamellar Bilayer: Its Structural Color and Mechanical Response

Abstract

A lot of animals and plants have structural color consisted of ordered structure. Recently attempts to introduce this ordered structure into polymer are attracting extensive attention in the field of sensor. We pay attention to dodecylglyceryl itaconate (DGI) that can form periodically ordered bilayer structure in water. This review describes synthesis, anisotropic structure and mechanical properties, and stress/straininduced change in structural color of a photonic hydrogel with ordered structure consisting of DGI and acrylamide.
