<p>A shape memory film formed from a shape memory transparent polymer, said shape memory film being capable of remembering a basic shape such as plane configuration and dead folds, taking on a second shape when the basic shape is modified (by changing the plane configuration and adding dead folds, twists, three-dimensional configurations, etc.) at a temperature higher than the glass transition point of the polymer and lower than the molding temperature of the polymer, and having the second shape set when cooled to a temperature lower than the glass transition point while being kept in the second shape; and a method of using said shape memory film by setting the second shape and subsequently heating the film to a temperature higher than the glass transition point, thereby causing the film to restore its basic shape.</p> |
