Due to the highly symmetrical structure of the PTFE material, it does not contain active groups, has high crystallinity, low surface energy, the surface is not easy to wet, and is highly hydrophobic.
Only through special treatment of PTFE film can the application range be wider.
With the continuous expansion of the application range of PTFE flat membranes, domestic and foreign researchers have conducted thorough research on the surface modification of PTFE membranes, which can be carried out through plasma treatment, functional monomer polymerization, chemical treatment and sputtering. Process effectively.
Improve its wettability and adhesion to improve its surface energy and improve its hydrophilicity.
