▎ 摘  要

NOVELTY - Graphene quantum dot reinforcing fiber comprises 3-10 pts. wt. graphene quantum dot master batch, 70-90 pts. wt. macromolecular master batch, and 1-3 pts. wt. filler. The graphene quantum dot master batch vomprises 3-7 pts. wt. graphene quantum dot, 2-3 pts. wt. dispersant and 90-100 pts. wt. polymer matrix. USE - The graphene quantum dot reinforcing fiber is used in antibacterial product (claimed). ADVANTAGE - The fiber improves the dispersibility of the graphene quantum dots in the matrix, antiviral, antibacterial, and anti-mite effects. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the graphene quantum dot reinforcing fiber, comprising (i) mixing the graphene quantum dot, polymer matrix and dispersant and extruding to obtain graphene quantum dot master batch; and (ii) mixing the graphene quantum dot master batch obtained in the step (i), macromolecule master batch and filler and spinning to obtain the graphene quantum dot reinforcing fiber.
