POLYTETRAFLUOROETHYLENE POROUS MEMBRANE, METHOD FOR PRODUCING SAME, AND BREATHABLE MEMBRANE AND BREATHABLE MATERIAL USING SAME |
摘要 |
The present invention provides a porous polytetrafluoroethylene membrane having a surface coated with a liquid-repellent agent. In this porous polytetrafluoroethylene membrane, the liquid-repellent agent is a polymer obtained by polymerization of monomers consisting essentially of CH 2 =CHCOOCH 2 CH 2 C 6 F 13 . This porous polytetrafluoroethylene membrane is suitable for use as a gas-permeable membrane that allows passage of gases but prevents entry of liquids and/or dust, specifically as a waterproof sound-transmitting membrane, a waterproof gas-permeable membrane, or a dustproof gas-permeable membrane. |
