Clean room FFU filter membrane is an excellent polymer material that is resistant to high temperature, corrosion resistance, excellent dielectric properties, stable chemical properties and good mechanical properties. Therefore, this material is widely used in engineering , military, and all aspects of life.
However, the polymer PTFE microporous membrane is non-polar and has a very low surface free energy, which makes its surface wetting and hydrophilic properties very poor, which affects its widespread application in actual production.
