Title: The Innovative Journey of George Lopatin
Introduction
George Lopatin, an accomplished inventor based in Newton Centre, MA, has made significant contributions to the field of materials science with a particular focus on fluorocarbon membranes. With a remarkable portfolio of eight patents, Lopatin's work exemplifies the intersection of science and innovation, demonstrating how industrial applications can lead to advancements in technology.
Latest Patents
Among Lopatin's latest inventions is a groundbreaking process for producing fluorocarbon membranes and a corresponding membrane product. This innovative method revolves around the use of microporous or open ultrafiltration poly (tetrafluoroethylene-co-perfluoro-(alkyl vinyl ether)) (PFA) or poly (tetrafluoroethylene-co-hexafluoropropylene) (FEP) film membranes or hollow fibers. The process includes forming a melt blend composed of 10 to 35 weight percent of PFA or FEP with a chlorotrifluoroethylene oligomer solvent. A unique aspect of this invention is that during shaping, one or more surfaces of the melt blend are coated with the solvent, resulting in an enhancement of the pore size on the membrane surface compared to membranes without solvent coating. The subsequent cooling and shaping procedures effectuate phase separation and crystallization of the PFA or FEP, with the solvent later being extracted. Remarkably, the porous PFA or FEP can then be heat-set under restraint to prevent any shrinkage.
