Latest Patents
Kawamoto's latest patents include innovative processes for creating microporous membranes. One of his patents details a process for making a microporous membrane from a blend containing a poly(phenylene sulfide) polymer. This invention involves forming a mixture of the polymer, an amorphous polymer, and optionally a plasticizer, followed by heating, extruding or casting the mixture into a membrane, and controlled cooling or coagulating the membrane. The process also includes leaching the membrane, with the option to draw the membrane at various stages.
Another significant patent focuses on the preparation of a microporous permselective membrane from a poly(phenylene sulfide) polymer. This process involves creating a homogenous mixture with an organic compound that solubilizes the polymer below its melting point. The mixture is then heated, extruded or cast into a membrane, and subsequently quenched or coagulated. This innovation is particularly useful for separating gaseous or liquid components from mixtures.
