Description

technical field [0001] The invention relates to the field of fiber technology, in particular to a graphene-reinforced antistatic and antibacterial composite fiber and a preparation method thereof. Background technique [0002] Graphene has excellent optical, electrical, and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery, and is considered to be a revolutionary material in the future. The arrangement of carbon atoms in graphene is the same as that of graphite monoatomic layer, which is bonded by sp2 hybrid orbitals, and has the following characteristics: carbon atoms have 4 valence electrons, of which 3 electrons form sp2 bonds, that is, each carbon atom has Donate an unbonded electron located in the pz orbital, the pz orbital of the adjacent atom is perpendicular to the plane to form a π bond, and the newly formed π bond is in a half-filled state. Studies have confirmed that ...
