  • Patent number: 11154055
    Abstract: A micro structure and antifouling active substance synergistic antifouling material and a preparation method thereof are provided. The micro structure and antifouling active substance synergistic antifouling material includes a matrix arrangement formed by a plurality of micro structure basic units in a cylindrical structure, an inner lower layer of each micro structure basic unit is filled with an antifouling active substance, and an inner upper layer of the each micro structure basic unit is filled with a sealing agent. A process for preparing a micro structure and antifouling active substance synergistic antifouling material includes three steps of preparing a micro structure, preparing a liquid antifouling active substance and preparing a synergistic antifouling material.

  • Patent number: 11000034
    Abstract: 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.
