| titleOfInvention | Preparation method of super-hydrophilic PPS composite fiber membrane |
| abstract | The invention discloses a preparation method of a super-hydrophilic PPS composite fiber membrane. The method grafts NO on the surface of the PPS porous membrane by reaction with strong oxidizing acid 3‑ 、ClO ‑ 、SO 4‑ 、SO 3‑ 、ClO 4‑ And (3) converting a hydrophobic membrane into a hydrophilic membrane by using hydrophilic groups, coating hydrophilic cellulose and hydrophilic modified inorganic nanoparticles on the surface of the hydrophobic membrane, adjusting the hydrophilicity and the membrane surface aperture of the fiber membrane, and finally preparing the super-hydrophilic PPS composite fiber membrane by using a hot pressing method. The invention utilizes the excellent physical and chemical properties of the PPS non-woven fabric to modify the surface of the membrane, does not damage the internal matrix structure and pore structure of the membrane, and prepares the super-hydrophilic PPS composite fiber membrane with good hydrophilicity, high interception efficiency, large flux, pollution resistance, high strength, good tensile resistance and solvent resistance and high recycling rate. |
