Title:
METHOD FOR PREPARING MULTIFUNCTIONAL GRAPHENE OXIDE AND METHOD FOR PREPARING PVCPVDF COMPOSITE FILM
Document Type and Number:
WIPO Patent Application WO/2024/031541
Kind Code:
A1
Abstract:
The present invention is suitable for the field of high polymer materials, and provides a method for preparing a multifunctional graphene oxide and a method for preparing a PVCPVDF composite film. By using graphene oxide as a substrate and using surface-initiated ring-opening metathesis polymerization to polymerize, on the surface of graphene oxide, a fluorine-containing hydrophobic monomer and a low polyethylene glycol antibacterial monomer and perform copolymerization, the final finished material is obtained. The final finished material is applied to the PVCPVDF composite film as a distillation film, thus improving the efficiency of using the PVCPVDF composite film and extending the service life of the PVCPVDF composite film.
