Latest Patents
One of Chubin's latest patents is for a porous membrane structure and method. This invention involves a method of treating a membrane that includes providing a structure of nodes and fibrils. The surfaces of these nodes and fibrils define a plurality of pores extending through the membrane. The membrane is constructed from expanded polytetrafluoroethylene material. A water-based dispersion of oleophobic fluoropolymer solids in a water-soluble solvent is utilized, which has specific surface tension and relative contact angle properties. This ensures that the diluted dispersion cannot wet the polytetrafluoroethylene material of the membrane. The dispersion is then diluted with a liquid wetting agent to allow it to wet the membrane. The surfaces of the nodes and fibrils are coated with the solids in the diluted dispersion, and the wetting agent material along with other fugitive materials are removed. Finally, the solids in the diluted dispersion are thermally coalesced on the surfaces of the nodes and fibrils without completely blocking the pores in the membrane.
