Mesostructured film, porous film and the method of preparing the same
First Claim
1. A method for producing a mesostructred film film comprising the steps of:
- preparing a reaction solution containing a precursor material for mesostructred film which contains a metal oxide, and an amphiphilic material;
applying the reaction solution onto a substrate having a capability of orienting an aggregate of the amphiphilic material in a predetermined direction; and
forming the mesostructred film having a plurality of the aggregates of the amphiphilic material oriented in the predetermined direction while holding the substrate onto which the reaction solution has been applied in a vapor-containing atmosphere.

Abstract
It is an object of the present invention to provide a method for preparing mesostructured film having oriented channel structure and which is applicable to preparing mesostructured metal oxide. It is also an object of the present invention to provide meso porous film containing non-silica metal oxide in pore wall and having rod-like pores uniaxially aligned. It is further an object of the present invention to provide method for preparing mesostructured film including the steps of: preparing a reactant solution containing a precursor material for frame of mesostructured material which contains metal oxide, and an amphiphilic material; coating the substrate whose surface has alignment control ability with the reactant solution; and holding the substrate which has been coated with the reactant solution in a vapor-containing atmosphere.
