Title:
GRAPHENE COMPOSITE ANTIBACTERIAL MASTERBATCH, GRAPHENE QUANTUM DOT REINFORCED FIBER AND GRAPHENE QUANTUM DOT COMPOSITE FILM, PREPARATION METHOD THEREFOR, AND APPLICATION THEREOF
Document Type and Number:
WIPO Patent Application WO/2023/000606
Kind Code:
A1
Abstract:
The present invention provides a graphene composite antibacterial masterbatch, a preparation therefor, and an application thereof. The raw materials for preparing the graphene composite antibacterial masterbatch comprise a combination of specific parts of silver-plated graphene quantum dots, a polymer matrix, dopamine, and polyvinylpyrrolidone. The silver-plated graphene quantum dots are added into the polymer matrix, such that the polymer matrix has antibacterial and antiviral effects; and dopamine and polyvinylpyrrolidone together are further selected as dispersants and generate a synergistic effect, such that the dispersity of the silver-plated graphene quantum dots in a polymer matrix and the compatibility of the silver-plated graphene quantum dots and the polymer matrix are improved, and the antibacterial and antiviral properties and the mechanical properties of the graphene composite antibacterial masterbatch are further improved.
