Description

technical field [0001] The invention relates to a conductive heating cloth, which belongs to the field of carbon materials. Background technique [0002] With the development of society, people's requirements for materials are getting higher and higher, which makes the development of materials change with each passing day. New carbon materials have excellent properties that traditional materials cannot match, such as low density, high electrical conductivity, high thermal conductivity, and small thermal expansion. Graphene is a new type of thin film material with a single layer of carbon atoms arranged in a hexagonal network structure. Single-layer graphene is the thinnest and strongest material among known materials. These excellent properties make it of great application value in the fields of electronics and even heating. [0003] Conductive heating cloth refers to a cloth or film with conductive heating function, which is usually obtained by blending conductive fibers w...
