The invention relates to a preparation method of a silane-modified polyampholyte hydrogel high-adhesion coating which is antibacterial and resistant to seaweed adhesion. DAC, NaSS, a crosslinking agent, an initiator, deionized water and MEMO are mixed as Prepolymer solution, the surface of the substrate with hydroxylation treatment and silane treatment is covered with the prepolymer solution and formed into a hydrogel coating to obtain the antibacterial and seaweed-resistant silane-modified polyampholyte hydrogel Adhesive high adhesion coating. The present invention adopts silane-modified polyampholyte hydrogel, and through the coupling effect of silane and the synergistic effect of the ionic bond between the DAC molecular chain and the substrate, the hydrogel coating has excellent adhesion performance, and at the same time, the hydrogel is The coating has good antibacterial properties and resistance to diatom adhesion, and can be used as a preferred material for marine antifouling coatings with broad application prospects. |
