Research shows that people have long noticed that polytetrafluoroethylene (PTFE), which has the most outstanding comprehensive properties among polymer materials, has excellent high and low temperature properties and outstanding chemical stability. property, as well as good dielectric properties and hydrophobicity, it is an ideal membrane material for separating microparticles under some harsh conditions. Let’s take a look at porous polytetrafluoroethylene membrane.
Based on pore size screening and interface effects, porous membrane materials can achieve selective separation of substances and have been used in water treatment, energy , gas separation, biomedical and material detection and other fields have been widely used. However, there are still certain problems in these applications, such as high energy consumption, poor selective separation, membrane fouling, etc. Learning from the unique nano- and micro-scale pores existing in natural biofilms is the direction to solve these problems.
Porous polytetrafluoroethylene membrane is made of suspended polytetrafluoroethylene resin by molding, sintering, cooling into a blank, and then turning and calendering. Polytetrafluoroethylene microporous membranes are coated on various fabrics and substrates using special processes to become new filter materials. The membrane has small pore size, uniform distribution and large porosity. While maintaining air circulation, it can filter all dust particles including bacteria to achieve the purpose of purification and ventilation.
