Title:
PHOSPHORUS-BASED GRAPHENE CHITIN GEL PHOTO-THERMAL FILM AND PREPARATION METHOD THEREFOR AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2022/213652
Kind Code:
A1
Abstract:
Disclosed is a phosphorus-based graphene chitin gel photo-thermal film with a photo-thermal conversion water treatment function, which is prepared by: using phosphorus-based graphene and chitin as raw materials, wrapping and combining the phosphorus-based graphene and the chitin in an alkali solution system, and dissolving by means of a freeze thawing technology, tightly fusing the negatively-charged phosphorus-based graphene with positively-charged chitin, and scraping same to form a film. According to such technology, the biological material chitin is introduced into the field of photo-thermal water treatment for the first time, the prepared gel photo-thermal film has an efficient photo-thermal water evaporation performance, and seawater desalination and sewage treatment can be achieved.
