AI Technical Summary

Problems solved by technology

Fluorine-containing conductive polymers such as DuPont's Nafion resin have excellent electrical conductivity and chemical stability, and are widely used in fuel cells and chlor-alkali batteries, but there are still many shortcomings, such as the electrical conductivity is not high enough, and the normal temperature of its single film Conductivity (Conductivity) <0.1 (S / cm); high chemical penetration, unable to effectively block the penetration of toxic and harmful chemicals

[0003] Expanded polytetrafluoroethylene is prepared by using high-crystallinity polytetrafluoroethylene dispersion resin, which is obtained by biaxial stretching and expansion. It has a microporous structure closely combined with micron or nanofibers, and has excellent physical and chemical properties and mechanical properties. Waterproof, breathable and chemically stable, it has been used to manufacture wire and cable insulation materials, artificial blood vessels, sealing tapes, environmental protection filters, and clothing fabrics since the 1970s; but its disadvantage is that these micron or nanofibers are not puncture resistant. Well, and these micro or nano fibers will continue to be elongated and loosened after tension, resulting in deformation of the membrane tissue, resulting in a decline in functionality, seriously affecting the overall protective function of the membrane
