Title:
PROCESS FOR PRODUCING HONEYCOMB STRUCTURE WITH ISOLATED HOLES
Document Type and Number:
WIPO Patent Application WO/2006/090579
Kind Code:
A1
Abstract:
A material solution comprising a hydrophobic organic solvent and a polymeric material dissolved or dispersed therein is applied to a substrate to form a liquid film of the material solution. A gas containing water vapor is blown against the surface of the liquid film to thereby form holes in a honeycomb arrangement while utilizing the resultant water droplets as a template. The resultant filmy object is heated or exposed to a good solvent for the polymeric material to partly deform or remove the hole-surrounding structure and thereby isolate the individual holes. By this technique, a honeycomb structure having isolated holes can be thus produced through self-organization using droplets as a template.
