Abstract: Disclosed is a self-healing polysilsesquioxane and a hybrid film using the same. Once crosslinked, the polysilsesquioxane copolymer can self-heal within several minutes at 100-120° C. The self-healing polysilsesquioxane copolymer can be prepared into a hybrid material in the form of a film. Because the hybrid film has an excellent ability of self-healing the damage caused by external impact, it is applicable to wide applications such as gas separation membranes, etc., without limitation.
