Title:
PROCESS FOR PRODUCTION OF HONEYCOMB-LIKE POROUS MATERIAL
Document Type and Number:
WIPO Patent Application WO/2006/112358
Kind Code:
A1
Abstract:
A process for the production of honeycomb-like porous material made of a water-nonsoluble polymer, which comprises the step of applying a solution obtained by dissolving a water-nonsoluble polymer and a surfactant in a water-insoluble organic solvent and having an interfacial tension of 10 to 20mN/m against water to a substrate made of a metal or glass to form a thin film of the solution and the step of evaporating the organic solvent from the thin film on the substrate. This process can give a high-quality honeycomb-like porous material exhibiting a standard deviation of pore diameter of 10% or below in an area 100μm square. Further, another high-quality honeycomb-like porous material having a pore diameter of as small as 1nm to 100μm and a standard deviation of pore diameter of 10% or below can be obtained by conducting the evaporation of the solvent under a specified air stream. The honeycomb-like porous materials are useful as optical films such as photonic crystal, antireflection coating, and light diffusing plate; electronic materials such as molds of patterned resists or electrodes; cell culture substrata; separation membranes with uniform pore diameters; and so on.
