Abstract

The invention discloses a graphene magnetic stripe and a preparation method thereof. The graphene magnetic stripe comprises a carrier and a plurality of stripe belts smeared on the carrier at intervals, wherein the stripe belts are prepared through mixing of graphene and epoxy resin. Since a magnetic material can be formed through magnetization treatment of graphene which has stable chemical properties and anti-corrosion properties, no corrosion to the magnetic stripe prepared by using graphene instead of iron powder occurs when the magnetic stripe is applied to a high-salt, humid or easily corrosive environment for a long period of time, so that information is recorded for a long period of time, and information loss is avoided.

Description

technical field [0001] The invention relates to the field of magnetic strips, in particular to a graphene magnetic strip and a preparation method thereof. Background technique [0002] Graphene is not only an excellent electrical and thermal conductive material, but it can also be magnetized to form a magnetic material. The magnetic strip is a thin layer of material (also known as pigment) composed of aligned ferrous oxide particles, tightly bonded together with a resin adhesive, and bonded to a non-woven material such as paper or plastic. On the magnetic substrate medium; the magnetic strip is essentially the same as the tape or disk used in the computer, and it can be used to record letters, characters and digital information. [0003] Since the existing magnetic strip is usually made of iron powder and other materials, it is easily corroded in a high-salt, humid or corrosive environment, so that the information recorded on the magnetic strip is lost. [0004] Therefore,...
