| titleOfInvention | A kind of polymer microfiltration membrane and its preparation method and use |
| abstract | The invention discloses a polymer microfiltration membrane and its preparation method and application. The surface and interior of the microfiltration membrane are interconnected three-dimensional network pore structures, the polymer fibers of the microfiltration membrane are interwoven to form a three-dimensional fiber network structure like a loofah structure, and the cross-section of the microfiltration membrane is along the thickness direction of the membrane. The upper part is a structure with a polymer fiber skeleton and the same type of holes distributed. The polymer microfiltration membrane of the invention has the characteristics of high penetration, high specific surface area, special wettability and ultra-low oil adhesion. The membrane is made of high molecular polymer and obtained by a combination of atomization pretreatment and non-solvent induced phase separation method, and can be used for gas filtration, liquid filtration, adsorption materials, catalysis, drug sustained-release materials, and anti-adhesion coatings , oil transportation, oil spill interception, etc. |
