Latest Patents
McTopy's latest patents include innovations in asymmetric permselective polyacetylene membranes. His first patent describes a process for creating asymmetric polyacetylene polymer membranes that exhibit both improved selectivity and enhanced flux. This process involves forming a solution containing 1% to 5% by weight of a polyacetylene polymer in a suitable solvent, creating a thin film, and quenching it in an aqueous bath with a specific surfactant concentration.
The second patent focuses on increasing the selectivity of anisotropic gas separation membranes. This process treats the membranes to alter the microporosity of their thin, dense layer, which is crucial for selectivity in gas separations. By applying a polar activator and exposing the membrane to microwave frequency radiation, the selectivity is enhanced with minimal impact on flux.
