Latest Patents

Rongrong Hao holds a patent for a preparation method for high-moisture-permeability fluorine-containing super-oleophobic microporous membranes. The patent outlines a detailed process that includes several steps: first, preparing a white opaque mixture of fluorine-containing polymers by adding materials in a specific weight ratio. The mixture is then stirred uniformly in a non-shear manner. The components include a blend of high molecular weight polytetrafluoroethylene dispersion resin and fluorine-containing ion exchange resin, along with fluorine-containing alkyl acrylate or methacrylate monomers, polyurethane acrylate prepolymers, and a high-temperature free radical initiator. The subsequent steps involve pouring the mixture into a blank pressing column, pressing it, calendering into strips, and finally stretching and thermally shaping to form the membrane.
