Abstract

The invention discloses an in-situ polymerized and modified white graphene-polyester composite slice and a preparation method thereof. The n-situ polymerized and modified white graphene-polyester composite slice is prepared from the materials of 50-80% of terephthalic acid, 10-40$ of ethylene glycol, 0.1-10% of white graphene and 0.1-1% of modifier, wherein the modifier is composed one or more selected from polyvinyl alcohol, hydroxy propyl cellulose, polyethylene glycol, sodium lignin sulfonate, polyvinylpyrrolidone, sodium dodecyl benzene sulfonate, lauryl pyrrolidone, dimethylformamide andisopropanol. The preparation method of the in-situ polymerized and modified white graphene-polyester composite slice comprises, firstly, preparing a modified white graphene / ethylene glycol slurry; secondly preparing a terephthalic acid / ethylene glycol / modified white graphene slurry; thirdly, performing esterification reaction; fourthly, performing polycondensation reaction; fifthly, performing discharging and pelletizing. The prepared in-situ polymerized and modified white graphene-polyester composite slice has the advantage of resistance to bacteria, far infrared and ultraviolet; the white graphene is less prone to falling off and functionally durable.

Description

technical field [0001] The invention relates to a polyester composite slice and a preparation method thereof, in particular to an in-situ polymerization-modified white graphene polyester 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 ...
