Abstract This work reports a silicone coating (PDMS-UIa) with marine antifouling and self-healing properties, which was prepared by the first synthesis of polydimethylsiloxane polymer containing imine and urea groups and then adding a small amount of eco-friendly antifoulant. The characteristic structure of the polymer was verified via Fourier transform infrared spectroscopy (FT-IR) and nuclear magnetic resonance (NMR). The PDMS-UIa coating has rapid self-repairing performance, excellent transparency and the ability to control the release of antifouling agents at a certain rate. The adhesion experiment using four typical benthic diatoms indicated that the PDMS-UIa coating can effectively inhibit the attachment of diatoms, which effectively improves the static antifouling ability of silicone materials.

抑制底栖硅藻粘附的自修复有机硅涂层的制备

摘要 本工作报道了一种具有海洋防污和自修复性能的有机硅涂料（PDMS-UIa），它是通过首先合成含有亚胺和脲基团的聚二甲基硅氧烷聚合物，然后加入少量环保型防污剂而制备的。通过傅里叶变换红外光谱 (FT-IR) 和核磁共振 (NMR) 验证了聚合物的特征结构。PDMS-UIa涂层具有快速自修复性能、优异的透明性和一定速率控制防污剂释放的能力。使用四种典型底栖硅藻的粘附实验表明，PDMS-UIa涂层能有效抑制硅藻的附着，有效提高有机硅材料的静电防污能力。
