The composite chip prepared by the invention has the characteristics of antibacterial, far-infrared and ultraviolet resistance, and the white graphene therein is uniformly dispersed, not easy to fall off, and has long-lasting function.

Description

technical field [0001] The invention relates to a nylon composite slice and a preparation method thereof, in particular to an in-situ polymerization-modified white graphene nylon composite slice and a preparation method thereof. Background technique [0002] "White graphene" is an alias for the nano-flakes obtained after exfoliation of hexagonal boron nitride (English name Hexagonal Boron Nitride, abbreviated as h-BN) whose grains are lamellar structures. Since the structure of hexagonal boron nitride is very similar to that of graphite, it has a hexagonal layered structure, soft texture, strong machinability, and white color. Corresponding to graphene, so hexagonal boron nitride is called "white graphene". [0003] Both hexagonal boron nitride and graphene are layered two-dimensional materials with a thickness of only one atom. , Covalent bonding between heteroatoms of nitrogen. [0004] The highly similar crystal structure gives white graphene and graphene some common c...
