摘　　要：仿生防污涂料是通过模拟海洋生物的皮肤和结构,或者提取海洋生物体内的防污物质制备出的防污涂料。本文采用简单盐溶解法,通过模拟软珊瑚上层透明层和下层多孔层的复合结构,以不同方式添加软珊瑚体内的防污化学物质糖精、加巴喷丁和正癸酸,制备了组成不同的仿生防污涂料,并对涂料的防污性能进行了研究。研究结果表明,糖精∶加巴喷丁∶正癸酸为47∶23∶25样品的压缩模量最小,糖精∶加巴喷丁∶正癸酸为42∶33∶25样品和糖精含量为0.01 g的样品压缩模量次之。压缩模量越小,越容易变形。糖精∶加巴喷丁∶正癸酸为47∶23∶25样品的透明层和多孔层的表面能最小,分别为22.2 mJ/m^(2)和16.0 mJ/m^(2)。糖精∶加巴喷丁∶正癸酸为42∶33∶25样品和糖精含量为0.01 g样品的透明层和多孔层的表面能次之,分别为22.7 mJ/m^(2)、22.9 mJ/m^(2)和16.1 mJ/m^(2)、16.5 mJ/m^(2)。表面能越小,疏水性越好,防污性能越好。对样品进行了抗污渍实验和静态抑菌实验,研究表明:和加入单一防污组分的仿生防污涂料相比,将三种防污组分全部加入的仿生防污涂料具有更好的防污效果;加入糖精的样品比加入其它单一防污组分的样品防污效果更好。The bionic anti-fouling coating is an anti-fouling coating prepared by simulating the skin and structure of marine organisms,or extracting the anti-fouling substances in the body of marine organisms.In this paper,the simple salt dissolution method was used to simulate the composite structure of the upper transparent layer and lower porous layer of soft coral.The anti-fouling chemical substances of saccharin,gabapentin and capric acid in soft coral were added in different ways to prepare bionic antifouling coatings with different compositions,and the fouling resistance of the coatings was studied.The results showed that the compression modulus of the sample with the ratio of saccharin∶gabapentin∶capric acid of 47∶23∶25 was the smallest,followed by the sample with the ratio of 42∶33∶25 and the sample with 0.01 g saccharin.The smaller the compression modulus,the easier it is to deform.The surface energy of the transparent layer and porous layer of the sample with the ratio of saccharin∶gabapentin∶capric acid of 47∶23∶25 was the smallest,which was 22.2 and 16.0 mJ/m^(2),respectively.The surface energy of the transparent layer and porous layer of the samples with the ratio of saccharin∶gabapentin∶capric acid of 42∶33∶25 and 0.01 g saccharin was second,which was 22.7,22.9 and 16.1,16.5 mJ/m^(2),respectively.The smaller the surface energy,the better the hydrophobicity and anti-fouling performance.The samples were tested for stain resistance and static antibacterial experiments.The research showed that compared with the bionic anti-fouling coatings with single anti-fouling component,the bionic anti-fouling coating with all three anti-fouling components had better anti-fouling effect.The sample with saccharin had better anti-fouling effect than that with other single anti-fouling components.
