Title: Innovations of C C Chau in Membrane Technology

Introduction

C C Chau is a notable inventor based in Midland, MI (US), recognized for his contributions to membrane technology. He has been awarded 3 patents that showcase his innovative approaches in the field. His work primarily focuses on the development of microporous membranes, which have significant applications in various industries.

Latest Patents

One of C C Chau's latest patents is a "Process for preparing microporous membranes." This process involves coextruding a melt of multiple interdigitated layers of at least two polymers, where one polymer has preferential solubility over the other. The method includes dividing and reorienting the layers into discrete domains of random orientation, ultimately forming a thin membrane or similar article. The preferentially soluble polymer is then leached out of the resulting article, creating a functional microporous membrane.

Another significant patent is the "Process of making a porous membrane." This method prepares porous membranes with a homogeneous microporous structure and a narrow pore size distribution, making them useful for ultrafiltration, distillation, and as substrates for composite membranes. The process includes preparing films, pellets, or sheets with alternating microlayers of high-density polyethylene and polystyrene, recoextruding these materials, and then pulverizing them into fine granules or powder. The granules are compression molded or sintered into thin films, which are then immersed in a solvent bath to selectively dissolve one component, resulting in a porous membrane.
