摘要

As an environmentally friendly antifouling strategy, a series of textured modified silicone surfaces with different textures, shapes and surface roughnesses were fabricated by mimicking the microstructures of abrasive paper via a simple replication method. The physical and chemical properties of the as-prepared coatings were systematically characterized by FT-IR spectroscopy, SEM and contact angle measurements. The antifouling efficacy of all coatings was evaluated by recording the settlement of fouling microalgae, including Nitzschia closterium f. minutissima, Phaeodactylum tricornutum and Chlorella, in the laboratory. The results indicated that the positive and negative replicas of both 800-grit and 1200-grit abrasive paper with morphology feature sizes larger than algae size encouraged the algae settlement. Only the positive replica of 5000-grit abrasive paper whose morphology feature size was smaller than algae size was effective in inhibiting N. closterium, P. tricornutum and Chlorella, and the reduction ratios were 49%, 75% and 81%, respectively. The positive replica of 7000-grit abrasive paper can reduce the amount of N. closterium and P. tricornutum by 29% and 57%, respectively. But it can't inhibit the settlement of Chlorella. The effect of surface morphology and wettability on the antifouling performance of textured coatings was discussed.

Minutissima，Phaeodactylum Tricornutum和小球藻，在实验室中。结果表明，800砂砾和1200粒砂纸的正阴性复制品与藻类大小大的形态特征尺寸促进了藻类沉降。只有5000粒砂纸的阳性复制品，其形态特征尺寸小于藻类尺寸的抑制术抑制N.Tricornutum和小球藻，分别为49％，75％和81％。 7000粒砂纸的阳性复制品可以分别将N型次数和P. Tricornutum的量减少29％和57％。但它不能抑制小球藻的沉降。讨论了表面形态和润湿性对纹理涂层防污性能的影响。
