Abstract

The invention discloses a preparation method of a low-temperature graphene-based nanoborate composite material. The preparation method comprises the following steps: 1) firstly, mixing graphene oxide, alkyl phenol, NN-dimethyl acetamide and water by using an ultrasonic method, and then performing ultrasonic dispersion to obtain mixed liquid; 2) adding calcium hexadecyl borate and nanometer cerium borate into the mixed liquid while stirring by using a motor, keeping the constant temperature for a certain time, continuing stirring and slowly adding sodium borohydride and sodium citrate to form a mixed solution; 3) performing a refluxing reaction in an oil bath at the reaction temperature of 150-200 DEG C while stirring by using a motor-driven stirrer, performing hot suction filtration after the reaction, washing and drying to obtain the graphene-based nanoborate composite material. By the preparation method, a solution synthesis method is adopted, the graphene oxide is reduced and the nanoborate composite material is prepared; by the preparation method, the main process is simple, the reaction condition is mild, the batch production is easily achieved and the the operation is convenient.
