Nontoxic antifouling coatings have been investigated for many years as possible successors to toxic antifouling paints. Polymers containing fluorine or silicone have been tested and each has been shown to be partially effective for different reasons. This paper describes a new coating which combines the best features of fluorinated and silicone coatings and is non-toxic. Four fluorinated elastomers were prepared and tested for fouling resistance during a full fouling season. The surface energy and mechanical properties of each polymer were measured and correlated to fouling performance. One of the elastomers was shown to foul slowly, clean easily, be durable in the marine environment and organisms bonded to it only weakly. The surface energy, elastic modulus, and thickness of the elastomer may be varied as desired over wide ranges to meet differing performance requirements.
无毒防污涂料作为有毒防污漆可能的替代品已被研究多年。含氟或硅氧烷的聚合物已进行测试，结果表明每种聚合物因不同原因都有一定效果。本文介绍了一种结合了含氟涂料和硅氧烷涂料最佳特性且无毒的新型涂料。制备了四种含氟弹性体，并在整个污垢季节测试其抗污性能。测量了每种聚合物的表面能和机械性能，并将其与污垢性能相关联。其中一种弹性体被证明污垢缓慢、易于清洁、在海洋环境中耐用且附着在其上的生物附着力较弱。弹性体的表面能、弹性模量和厚度可根据需要在很宽的范围内变化，以满足不同的性能要求。
