▎ 摘　　要

NOVELTY - Preparing graphene aluminum-adding composite slurry by electrostatic adsorption comprises preparing graphene oxide, centrifuging the obtained graphene oxide to obtain graphene oxide with substantially uniform size, adding the graphene oxide and granular aluminum powder into the mixed solution of water and alcohol, adding diluted hydrochloric acid solution, stirring the glass rod till the upper layer solution is clear, pouring the supernatant, and preparing graphene aluminum-increasing composite slider. USE - Method for preparing graphene aluminum-adding composite slurry by electrostatic adsorption. Uses include but are not limited to material, metallurgy, chemical engineering, electronic technology integrated electronic functional material, mixed integrated circuit, sensitive element, surface assembly technology, resistance network, display, and base material of various electronic discrete components. ADVANTAGE - The method is non-toxic, and the prepared graphene aluminum-increasing composite slurry has good dispersibility. The method avoids using organic surfactant which is difficult to remove, and obviously improves the dispersibility and conductivity of the composite liquid.
