Advantages and disadvantages of graphene electric blanket are as follows: Advantages Graphene floor heating belongs to a kind of electric floor heating, and many properties of electric floor heating can be improved by coating graphene, which belongs to a new generation of electric floor heating. Graphene electric blanket has two shortcomings: first, graphene material is not industrialized and its performance is extremely unstable; Second, graphene is extremely expensive.

Graphene is a kind of sp-based graphene? Hybrid carbon atoms are closely packed into a single-layer two-dimensional honeycomb lattice structure. Graphene has excellent optical, electrical and mechanical properties, and has important application prospects in the fields of material science, micro-nano processing, energy, biomedicine and drug delivery, and is considered as a revolutionary material in the future.

Physicists Andrei Grimm and Konstantin Novoselov of the University of Manchester in England successfully separated graphene from graphite by micromachining, so * * * won the 20 10 Nobel Prize in Physics. The common methods of graphene powder production are mechanical stripping, redox and SiC epitaxial growth, and the method of thin film production is chemical vapor deposition (CVD).
