Title: Innovations of Richard C. Chang
Introduction
Richard C. Chang is an accomplished inventor based in Raleigh, NC. He has made significant contributions to the field of fluid separations through his innovative processes and methods. With a total of 2 patents, Chang's work has had a notable impact on membrane technology.
Latest Patents
Chang's latest patents include "Processes for coating bundles of hollow fiber membranes" and "Method for enhancing membrane separation." The first patent discloses processes for coating the exteriors of a plurality of hollow fibers suitable for fluid separations. This process involves immersing the bundle of hollow fibers in a coating liquid, which contains material suitable for forming the coating and a substantial amount of solvent. A pressure drop from the exteriors to the interiors of the hollow fibers results in the formation of a deposit on the exteriors, enabling the entire exterior surfaces to be coated without undue sticking or thick coatings. The second patent focuses on enhancing the selectivities of fluid separations of membranes by storing them in water. This method improves membranes made from materials that are not unduly susceptible to biodegradation, ensuring they maintain beneficial mechanical and fluid separation properties after drying.
