The formation of the micro–nano structures in the PTFE membrane was ascribed to PTFE crystallization. By controlling the cooling rate during membrane formation, various PTFE membranes with different structures and properties prepared, which showed a super-hydrophobicity with a water static contact angle (155°) and a sliding angle (8.3°) owing to their micro–nano structures.
Our unsupported, hydrophobic, PTFE membrane filters are ideal for sterilization and venting applications involving air, gasses, and solvents/acids incompatible with most other filters. Chemicals, Petrochemicals, and Fertilizers Computers, Semiconductors, and
