On/off switching of structural color by using multi-bilayered films containing copolymers having azobenzene and biphenyl side groups

Abstract: In this paper, the change in structural color of multi-bilayered films fabricated by stacking copolymers, PMAz–PMBP (m : ), consisting of azobenzene and biphenyl side chain groups, and polyvinyl alcohol (PVA) alternately, was investigated.

“…Multi-bilayered lms were prepared according to previous reports. 18,19,21 Az-containing copolymers were dissolved in cyclohexanone at 4.5 wt% and PVA was dissolved in water at 2.5 wt%. The solutions were spin coated at 3000 rpm on a glass substrate alternately and repeatedly, and 20-bilayered lms were prepared.…”

“…For multi-bilayered lms consisting of Az copolymers with biphenyl groups such as the LC mesogen groups, the light response speed was faster than that of the Az homopolymer. 21 However, the reection intensity deteriorated due to the low refractive index of the biphenyl group as reection intensity relied on the refractive index difference of composite materials.…”
