The invention provides a preparation method of a composite antibacterial aerogel material based on graphite phase carbon nitride, and belongs to the technical field of antibacterial materials, and the preparation method specifically comprises the following steps: (1) calcining carbon nitride powder in an air atmosphere at a high temperature to obtain an ultrathin two-dimensional graphite phase carbon nitride material; (2) putting the material obtained in the step (1) into a specific solution, and carrying out ultrasonic treatment to form a uniformly dispersed turbid solution; (3) putting the chitosan-based material into an acetic acid solution, and carrying out ultrasonic treatment to form a uniform solution; and (4) dropwise adding the product obtained in the step (3) into the product obtained in the step (2), and freeze-drying the reacted liquid to obtain a final product. The invention provides the preparation method of the composite antibacterial aerogel material based on the graphite phase carbon nitride,
