VOID STRUCTURED FILM BONDED THROUGH CATALYTIC ACTION AND METHOD FOR MANUFACTURING SAME

摘要

To provide a void structured film which forms a porous structure having, for example, high porosity while suppressing occurrence of cracks and also has strength.SOLUTION: The void structured film of the present invention includes one or a plurality of kinds of structural units which form a fine void structure. The constitutional units are chemically bonded to each other through catalytic action. For example, the void structured film of the present invention has abrasion resistance measured with BEMCOT (trade mark) in the range from 60% to 100%, and folding endurance measured by the MIT test is 100 times or more. The void structured film can be produced, for example, by forming a precursor of the silicone porous body using sol containing a pulverized product of a gelled silicon compound and then chemically bonding the pulverized product contained in the precursor of the silicone porous body. The chemical bonding of the pulverized product with each other is, for example, preferably chemical crosslinking thereof.SELECTED DRAWING: None
