Materials with surface structures exhibit optical functionalities such as diffraction and antireflection and have attracted much attention for developing various optical elements. Recently, we demonstrated the formation of microscale well- and canal-like surface structures triggered by patterned photopolymerization. The photopolymerization with structured light causes molecular diffusion in the liquid-crystalline polymer films, leading to the formation of both surface structures and molecular alignment. In this study, we investigated the thermal responsiveness of the microsurface structures of the molecularly aligned film, and analyzed their optical diffraction properties.
