Title:
POROUS POLYMER-MODIFIED METAL CARBON NANOTUBE COMPOSITE FILM, PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/121102
Kind Code:
A1
Abstract:
Disclosed are a porous polymer-modified metal carbon nanotube composite film, a preparation method therefor and the use thereof. The method comprises the following steps: mixing an acidified carbon nanotube film with a modification liquid, and then heating and reacting same to obtain a modified carbon nanotube film; and then coating the surface of the modified carbon nanotube film with polyethylene glycol, then coating the surface with a porous polymer solution, and heating same to obtain the porous polymer-modified metal carbon nanotube composite film. A metal carbon nanotube composite film coated with a porous polymer is successfully prepared, efficient nanofiltration and separation of multiple dyes is achieved, and the separation efficiency for multiple tested dyes reaches 90% or above. In addition, the film material is easy to manufacture, has wide applicability with regard to dye separation and has much application potential.
