The invention discloses a hydrogel antifouling
fiber, a preparation method of hydrogel antifouling
fiber and a preparation method of an implanted type high-strength hydrogel antiflouling
coating layer, and relates to antiflouling materials, preparation methods of the antiflouling materials, and preparation methods of vessel
antifouling coating layers, for mainly solving the technical problems that the conventional PVA (
Polyvinyl Acetate)
fiber implanted type vessel antiflouling
coating layer is poor in antifouling effect and short in service life. The hydrogel antifouling fiber disclosed by the invention is a fiber with a core-shell structure, the shell layer of the fiber is made of
polyacrylamide, and the core layer is made of carbon
nano tube modified
polyacrylamide. The preparation method comprises the following steps: 1, preparing
polyacrylamide hydrogel, 2, preparing a core layer
spinning dope, 3, preparing a shell layer
spinning dope, 4,
spinning by using a wet method to obtain the hydrogel antifouling fiber. The preparation of the
antifouling coating layer comprises the following steps: spraying implantation gel onto a substrate, further implanting the hydrogel antifouling fiber into the substrate through a high-pressure static implantation technique, and
drying to obtain the implanted type high-strength hydrogel
antifouling coating layer. The
coating layer is not changed when being soaked in
seawater or
industrial water for 6 months, so that the coating layer can be applied to vessel antifouling.
