The difference between graphene and carbon fiber heaters
1. Different composition materials

1. Graphene: It is a two-dimensional carbon nanomaterial composed of carbon atoms in a hexagonal honeycomb lattice with a hybrid orbital sp.

2. Carbon fiber: Use electricity to make carbon fiber molecules oscillate through Brownian motion to obtain heat.

2. Different physical and chemical properties

1. Graphene: The arrangement of carbon atoms inside graphene forms bonds with graphene sp2 hybrid orbitals, and has the following characteristics: carbon atoms have four valence electrons, of which three electrons generate sp2 bonds, that is, each carbon atom contributes Instead of pz orbital bonding electrons, the pz orbital direction of adjacent atoms is perpendicular to this plane to form pi bonds, and the pi half fills the formation of new identities.

2. Carbon fiber: A large number of carbon microcrystals rub against each other and oscillate under the action of an electric field, and the crystals will undergo "Brownian motion" under the action of an electric field. A large number of experimental data have confirmed that the electrothermal conversion efficiency of carbon fiber crystal is more than 98%, which is more than 20% higher than the energy efficiency analysis of carbon fiber electric floor heating systems such as commonly used nickel-chromium alloy wires.
