Description

technical field [0001] The invention relates to the technical field of floor paint, in particular to a graphene antistatic floor paint and a preparation method thereof. Background technique [0002] Graphene is a single layer of carbon atoms tightly packed into a two-dimensional hexagonal honeycomb lattice structure, with sp 2 connected in a hybrid manner. Microscopically, the single-layer graphene film is not a two-dimensional flat structure, but has a "nanoscale" stable microwave-like single-layer structure, which is the only two-dimensional free-state atomic crystal found so far; macroscopically, graphite Alkenes can be warped into zero-dimensional fullerenes, rolled into one-dimensional carbon nanotubes or stacked into three-dimensional graphite. The existence of stable carbon six-membered rings in graphene's unique two-dimensional periodic honeycomb lattice structure endows it with excellent performance: the thickness of single-layer graphene is only 0.35nm, which is ...
