PHOTOSENSITIVE COMPOSITE MATERIAL, METHOD FOR PRODUCING SAME, AND METHOD FOR USING PHOTOSENSITIVE COMPOSITE MATERIAL FILM

WIPO Patent Application WO/2016/121651

A1

Provided is a material capable of being repeatedly used as an adhesive. This photosensitive composite material contains a polymer compound, a liquid crystal compound, and a photosensitive compound. The molecular shape of the photosensitive compound is reversibly changed by irradiation with ultraviolet light and visible light. The glass transition temperature of the photosensitive composite material is lowered by irradiation with ultraviolet light, and the glass transition temperature lowered by irradiation with ultraviolet light is increased by irradiation with visible light. The mass of the polymer compound is preferably 40-60% of the total mass of the photosensitive composite material, and the mass of the photosensitive compound with respect to the sum of the mass of the liquid crystal compound and the mass of the photosensitive compound is preferably 2-100%. An azobenzene derivative can be used as the photosensitive compound.
