The invention belongs to the technical field of
marine organism fouling protection, and particularly discloses a preparation method of a bionic self-compensation smooth
liquid injection micro-nano surface
antifouling coating, which comprises the following two core steps: 1, preparing an organic
silicon matrix with a bionic self-compensation function, and preparing an organic
silicon matrix with a bionic self-compensation function by utilizing reversible change / dissociation-reconstruction property of a dynamic
hydrogen bond; the self-repairing mechanism of the nature is simulated, and automatic compensation and continuous stability of the performance when the
coating is damaged are achieved; and secondly, on the basis of the organic
silicon substrate, smooth liquid is injected, and the elastic micro-nano antifouling surface is constructed in situ. Meanwhile, fluid resistance is reduced through a smooth liquid film on the surface of the
coating, and recognition and attachment of
fouling organisms are hindered; due to the surface design of the elastic micro-nano structure, surface damage caused by loss and deformation of a smooth liquid film on the surface of the
coating can be reduced, and the long-term stable antifouling performance is kept. The two components cooperate with each other, so that the antifouling property is effectively improved, and a broad-spectrum, more efficient and lasting antifouling solution is provided for the related fields of maritime work, water conservancy and the like.
