摘要

PROBLEM TO BE SOLVED: To develop a mesostructure into a functional element by orienting mesopores in a first direction parallel to a polymeric surface. ;SOLUTION: Each mesostructure 14 is formed in the state of an island on the surface of a polymeric film 12 or present in the form of a film. The mesostructure 14 has tubular mesopores 13 which are oriented in the direction parallel to the surface of the polymeric film 12 (the direction of an arrow A). In order to realize the constitution, the surface of the polymeric film 12 in contact with the mesostructure 14 is subjected to a rubbing treatment. For example, the surface of the polymeric film 12 formed on a prescribed substrate 11 is rubbed in the prescribed direction (in the direction of the arrow or the like) with a nylon or the like. An alkoxysilane is then hydrolyzed in the coexistence of a surfactant under, e.g. acidic conditions on the rubbing treated surface according to a conventional method to form the mesostructure 14 having the many tubular mesopores 13 on the surface of the polymeric film 12. The mesopores 13 are further oriented in the rubbing direction.;COPYRIGHT: (C)2001,JPO
