| 发明名称 | Gas-permeable filter provided with oil repellency | ||
| 摘要 | A gas-permeable filter provided with oil repellency is provided. The gas-permeable filter includes a porous membrane having a surface coated with an oil-repellent agent. The oil-repellent agent includes a linear fluorine-containing hydrocarbon group represented by —R1C5F10CH2C4F9 or —R2C6F13, and the porous membrane is a stretched polytetrafluoroethylene (PTFE) porous membrane. Here, R1 and R2 are each independently an alkylene group having 1 to 12 carbon atoms or a phenylene group. The gas-permeable filter is provided with oil repellency without significant reduction in gas permeability. | ||
