Problems solved by technology

However, due to the strong van der Waals force between the graphenes due to the nanometer size, it is very easy to agglomerate, so the dispersion of graphene in the polymer is not good, resulting in unstable performance of the prepared polymer material, which affects the use; secondly, due to the graphene Chemical stability, the interface binding force between it and other substances is poor, and the enhancement effect cannot be fully exerted

Description

technical field [0001] The invention relates to the field of conductive materials, in particular to graphene-enhanced conductive plastics and a preparation method thereof. Background technique [0002] With the rapid development of the electronics industry, people pay more and more attention to the static electricity elimination and electromagnetic shielding performance of plastics. Conductive plastics can generally be divided into structural conductive plastics and composite conductive plastics. Structural conductive plastics are conductive materials that are polymers themselves or modified by chemical doping. The cost is low, but the performance stability is not high, and the process is not yet mature. Composite conductive plastics refer to plastics that are electrically conductive after physical modification (such as filled with carbon black, etc.), and have the advantages of mature technology, stable performance, low cost, and simple methods. However, the mechanical str...
