Abstract

Barnacle adhesion strength was used to screen seventy-seven polydimethylsiloxane elastomeric coatings for fouling-release properties. The test coatings were designed to investigate the effect on barnacle adhesion strength of silicone fluid additive type, additive location, additive molecular weight, additive loading level, mixtures of additives, coating matrix type and coating fillers. The type of silicone fluid additive was the primary controlling factor in barnacle fouling-release. The type of silicone matrix in which the fluid resided was found to alter the effect on fouling-release. Two PDMS fluids, DMSC15 and DBE224, significantly reduced the adhesion strength of barnacles compared to unmodified elastomers. Optimum fouling-release performance was dependent on the interaction of fluid type and elastomeric matrix.

摘要

藤壶附着强度被用于筛选77种聚二甲基硅氧烷弹性体涂层的防污性能。测试涂层旨在研究硅油添加剂类型、添加剂位置、添加剂分子量、添加剂负载量、添加剂混合物、涂层基体类型和涂层填料对藤壶附着强度的影响。硅油添加剂类型是藤壶防污性能的主要控制因素。发现硅油所在的硅氧烷基体类型会改变对防污性能的影响。与未改性的弹性体相比，两种聚二甲基硅氧烷流体DMSC15和DBE224显著降低了藤壶的附着强度。最佳防污性能取决于流体类型和弹性体基体之间的相互作用。
