To produce ecological marine paints, it is necessary to understand the phenomena involved in antifouling activity. Due to the multivariable components which have to be taken into account and due to their analytical intricacy, only studies based on selected properties are conceivable. In this study, four properties have been chosen, viz. erosion, biocide release, roughness and the physicochemical characteristics of the film surface. A principal-component analysis (PCA) of the experimental data has shown that, among the selected properties, only erosion affected antifouling efficiency. A more detailed investigation of erosion by quantifying global hydration and hydrolysis of immersed paints revealed the difficulty in linking the chemical structure of binders to the final erosion properties. Biocide release from paints, quantified by chromatographic methods coupled with UV detection, was inferior to the doses stated by the paint producers. These observations allowed the conceiving of formulations with reduced amounts of active molecules. The development of erodable, biodegradable binders associated with non toxic compounds is a promising way to obtain efficient antifouling paints compatible with existing, preventive systems.
要生产生态海洋涂料，有必要了解防污活性所涉及的现象。由于需要考虑多种变量成分且其分析复杂，只能设想基于选定特性的研究。在本研究中，选择了四个特性，即侵蚀、杀菌剂释放、粗糙度和漆膜表面的物理化学特性。对实验数据的主成分分析（PCA）表明，在选定的特性中，只有侵蚀会影响防污效率。通过量化浸泡涂料的整体水合作用和水解作用对侵蚀进行更详细的研究，发现难以将粘合剂的化学结构与最终的侵蚀特性联系起来。通过色谱方法结合紫外检测对涂料中杀菌剂释放量进行量化，结果低于涂料生产商规定的剂量。这些观察结果使得可以设想减少活性分子用量的配方。开发与无毒化合物相关的可侵蚀、可生物降解的粘合剂是获得与现有预防系统兼容的高效防污涂料的一种有前景的方法。
