A new formation control technique of percolated structure of polystyrene-polybutadiene polymer blend was developed by using supercritical (SC) carbon dioxide solution containing organic solvent, such as benzene, toluene, or p-xylene. During the solvent casting process, the SC fluid mixtures which have large diffusivity were used as a solvent for the polymer blend under the conditions of 20 MPa and 308. 15 K. The periodic distance of the percolated structure was measured during the casting process by the laser-light scattering method. And the produced structure of polymer blend was observed by an optical microscope. A closed percolated structure of polymer blend was formed in the SC fluid process.
