Title: Gopakumar Thottupurathu: Innovator in Membrane Technology
Introduction
Gopakumar Thottupurathu is a notable inventor based in Overland Park, KS (US). He has made significant contributions to the field of membrane technology, holding a total of 7 patents. His innovative work focuses on enhancing the properties of polytetrafluoroethylene (PTFE) membranes, which have various applications in different industries.
Latest Patents
Among his latest patents, Gopakumar has developed a porous membrane that comprises a sheet of expanded polytetrafluoroethylene. This sheet includes a first extrudate made from a first PTFE fine powder resin mixed with processing lubricant at a specific lube rate. A second extrudate is also created from the same PTFE fine powder resin and lubricant. These extrudates are combined into an integrated tape structure that is stretched in both first and second directions. The resulting sheet is porous and exhibits a gas permeability of at least 0.1 CFM according to ASTM D737. Additionally, the sheet has an average Mullen Hydrostatic Burst pressure ranging from 135 psi to 175 psi according to ASTM D751.
Another significant patent involves a process to increase the oleophobicity of PTFE, resulting in oleophobic articles. This method includes creating an oleophobic layer on a fluoropolymer, such as PTFE, using a fluoroalkyl acrylate copolymer. The oleophobicity achieved is sufficient to repel #8 oil (n-heptane) in accordance with AATCC Test Method 118. This innovation also includes coated articles that feature fluoropolymers and oleophobic layers made from fluoroalkyl acrylate copolymers.
