Anti-fouling gel particles containing a rare earth/anti-fouling agent and a preparation method therefor, which belongs to the technical field of chemical materials. Firstly, white carbon black is prepared as a carrier by using a sol-gel method; the white carbon black is modified with a silane coupling agent, and a rare earth cerium solution is then added thereto to obtain a rare earth antimicrobial white carbon black with a good dispersity; and then the rare earth antimicrobial white carbon black and an anti-fouling agent are co-coated by means of a free radical copolymerization method, such that the prepared anti-fouling gel has double anti-fouling mechanisms of both a hydrophilic property for preventing bacterial adhesion and an anti-fouling agent for sterilization. The addition of the rare earth substance, on the one hand, can greatly improve the anti-fouling efficiency of the anti-fouling agent, and on the other hand, because the surface of the rare earth antimicrobial white carbon black is rich in a large number of hydroxyl groups, can form intramolecular or/and intermolecular hydrogen bonds with amide groups, such that the mechanical properties of the anti-fouling gel particles can be significantly enhanced and a long-lasting anti-fouling effect can be achieved. The anti-fouling gel particles containing the rare earth/anti-fouling agent have a simple preparation process and a rich source of raw materials, and can effectively reduce production costs.
