Abstract

The invention discloses graphene-glass and a preparation method thereof. Glass powder is modified by coupling agents, the modified glass powder and graphene oxide react and then are dried, thermal reduction of dried materials is performed to obtain lamellar graphene, the lamellar graphene is uniformly distributed in the glass to obtain the graphene-glass. Graphene in the graphene-glass accounts for 0.4%-1.5% of the total weight of the graphene-glass. The coupling agents are silane coupling agents, and the dosage of the coupling agents accounts for 1%-5% of the weight of the glass powder. The prepared graphene-glass can effectively solve the problem of reuniting of the graphene, uniform distribution of the graphene is ensured, fracture toughness and strength of the glass are effectively improved by adding the graphene, and use markets of the glass products are widened.

Description

technical field [0001] The invention relates to the technical field of graphene-glass preparation, in particular to a graphene-glass and a preparation method thereof. technical background [0002] Graphene is a single-layer atomic plane material. It is found by exfoliating graphite that it is composed of carbon atom sp2 hybrid orbitals. It is a hexagonal honeycomb lattice material with high specific surface area, high strength, high elastic modulus, and excellent thermal and electrical properties. The excellent properties of graphene make it the focus of scientific and industrial circles. The thickness of graphene is only 0.335nm, which is not only the thinnest among known materials, but also very firm and hard; as a single substance, it can transfer electrons faster than all known conductors and semiconductors at room temperature; The theoretical specific surface area is as high as 2630m 2 / g. Graphene is usually used as a reinforcing phase in materials, adding a small ...
