Efficient and low resistance multi-functional UV resistant polyphenylene sulfide non-woven hollow membrane.

The heat and corrosion resistance of traditional membranes is inadequate, thus making them inadequate for the separation/filtration needs of harsh environments. Polyphenylene sulfide(PPS) can be used to develop new-generation membrane materials, but PPS has problems such as hydrophobicity and UV resistance. This article proposes a PPS membrane for efficient separation/filtration under extreme conditions, which uses melt-blown PPS non-woven fabric and undergoes oxidation and nitrification modification.
