Abstract:
Biofouling on the surfaces of ship hulls can bring about some unwanted and detrimental consequences, and it has been recognized as a widespread problem. Toxic compounds, such as copper-based antifoulant, can prevent the happening of biological fouling, but they have negative impacts on non-target organisms and lead to detrimental ecological effects, thus it is necessary to develop new eco-friendly fouling-resistant materials. It is often observed that many plants and animals don’t experience biological fouling. Their antifouling methods usually come from chemical, physical, mechanical, behavioral or combinatorial mechanisms. Natural antifouling mechanisms may be used as the basis for antifouling materials, and most attention has been devoted to designs based on natural antifoulants, microtopography, hydrogel and protein-resistance. In this paper, the progress of biomimetic antifouling materials with natural antifoulants and various surface features, such as microtopography, hydrogel and protein-resistance, were introduced. Additionally, some significant research results on biomimetic antifouling materials in china were also presented, and the development trend of this field in the future was prospected.
