Due to the highly symmetrical structure of the PTFE material, it does not contain active groups, the crystallinity is high, the surface energy is low, the surface is not easy to wet, and the hydrophobicity is very strong. Only through special treatment of PTFE film can the application range be wider. With the continuous expansion of the application range of e-PTFE membrane, researchers at home and abroad have thoroughly studied the surface modification of PTFE membrane, which can be effectively treated by plasma treatment, functional monomer polymerization, chemical treatment and sputtering. . Improve its wettability and adhesion to improve its surface energy and improve its hydrophilicity. Unlike general e-PTFE microporous membranes, modified e-PTFE microporous membranes allow water to pass through. The particulate suspension in water is separated, which expands its applications in water purification, medical and sanitation.
