| 摘要 | PURPOSE:To individually use two shapes by molding shape memory transparent polymer at a predetermined temperature to store a basic shape such as a planar shape, a folding shape, etc., and molding a shape memory film. CONSTITUTION:After a film for storing a basic shape such as a planar shape, a folding shape, etc. is molded with shape memory transparent polymer, the film is added with a planar shape, a folding shape, an uneven shape, a twisting shape, etc. to the basic molding of the film at a temperature higher than a glass transition temperature and lower than the molding temperature. Then, it is cooled to a temperature lower than the transition temperature while holding the shape to solidify the second shape, it is then heated to a temperature higher than the transition temperature to recover the basic shape, and the film is used. The example of the polymer for molding the film includes urethane, styrene-butadiene polymers, etc. | ||||||
