Abstract
Description
technical field
[0001] The invention relates to the technical field of graphene conductive paste preparation, in particular to an automatic production process of graphene electronic conductive paste. Background technique
[0002] Graphene is a two-dimensional carbon nanomaterial composed of carbon atoms with sp hybrid orbitals in a hexagonal honeycomb lattice; graphene has excellent optical, electrical, and mechanical properties, and is widely used in materials science, micro-nano processing, energy, and biology It has important application prospects in medicine and drug delivery, and is considered to be a revolutionary material in the future; in fact, graphene exists in nature, but it is difficult to peel off the single-layer structure; graphene is stacked layer by layer to form graphite. Graphite 1 mm thick contains about 3 million layers of graphene; a pencil lightly drawn across the paper can leave traces of a few layers or even just a single layer of graphene. The chem...
