1. A composite film of fluorinated polybenzoxazole and triple-shelled mesoporous silica hollow spheres, comprising:
fluorinated polybenzoxazole as a matrix, and
amino-functionalized triple-shelled mesoporous silica hollow spheres, which are dispersed in the fluorinated polybenzoxazole matrix,
wherein, a mass ratio of (amino-functionalized triple-shelled mesoporous silica hollow spheres)/(fluorinated polybenzoxazole) is 1/100 to 5/100.
