Laboratory evaluation of antifouling coatings is underpinned by settlement studies with specific fouling organisms. Established methods provide insight into the likelihood of failure of a particular coating system, but can neglect the process of surface selection that often precedes attachment. The present approach for quantifying the exploratory behaviour of barnacle cypris larvae suggested that inspection behaviour can be a rapid and predictive proxy for settlement. Two series of xerogels with comparable total surface energy, but different dispersive and polar components, were evaluated. Settlement assays with three-day-old cyprids of Balanus improvisus demonstrated that while attachment was not linked directly to dispersive free energy, the composition of the xerogel was nevertheless significant. Behavioural analysis provided insight into the mechanism of surface rejection. In the case of a 50:50 PH/TEOS (phenyltriethoxysilane-based) xerogel vs a 50:50 TFP/TEOS (3,3,3-trifluoropropyltrimethoxysilane-based) xerogel, wide-searching behaviour was absent on the former.
实验室评价防污涂料的基础是对特定污损生物的附着研究。已建立的方法可以深入了解特定涂层系统失效的可能性，但可能忽略了通常先于附着的表面选择过程。目前用于量化藤壶幼体探索行为的方法表明，检查行为可以快速、准确地预测附着。评估了两种比表面积能相当但分散能和极性分量不同的干凝胶系列。用三天大的 B. improvisus 藤壶幼体进行的附着实验表明，尽管附着与分散自由能没有直接联系，但干凝胶的组成仍然很重要。行为分析提供了对表面排斥机制的深入了解。在 50:50 PH/TEOS（苯基三乙氧基硅烷基）干凝胶与 50:50 TFP/TEOS（3,3,3-三氟丙基三甲氧基硅烷基）干凝胶的情况下，前者不存在广泛搜索行为。
