摘要:
A controlled-release material sensitive and response to fouling organisms for an antifouling agent includes an encapsulating precursor and a crosslinking agent. A hyaluronic acid/polyL-lysine nano-shell controlled-release material is prepared by an alternating layer-by-layer self-assembly of hyaluronic acid and poly-L-lysine, and a polypropylene ammonium chloride/poly-L-glycine nano-shell controlled-release material is prepared by an alternating layer-by-layer sell-assembly of polypropylene ammonium chloride and poly-L-glycine. The crosslinking agent is composed of 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride and N-hydroxythiosuccinimide. Based on the specific catalytic hydrolysis characteristic of fouling organism extracellular proteases on the controlled-release material, the purpose of adjusting the release of antifouling agents adaptively with the change of fouling organisms in off-season/peak-season can be achieved, prolonging the service life of the antifouling coatings.
