Abstract
The invention relates to graphene and a low-cost preparation method thereof. The low-cost preparation method comprises the following steps: carrying out ultrasonic cleaning on plastic products; then crushing the plastic product and carrying out ball milling to obtain a plastic product micro-fragment; then carbonizing and carrying out the ball milling to obtain carbonized powder with fine granularity; carrying out secondary calcination on the carbonized powder; washing, purifying and drying to finally obtain the graphene. The graphene provided by the invention takes the plastic product or dailywaste plastic products, especially polyethylene plastic, polystyrene plastic and the like, as raw materials and the graphene is prepared through a specific technological method; the prepared graphenenot only has the advantages of low cost, controllable layer number, large specific surface area and high electric conductivity, and waste plastic is used as the raw material so that the environment protection pressure is greatly reduced; the method is suitable for preparation and production of the low-cost graphene and a result can be applied to researches of conducting materials, environment protection, coating, heat dissipation structures and solid propellants.
