This project will be with Advanced Converting Technologies (ACTI), a Canadian company that focuses on custom adhesive coatings and laminating processes. ACTI has begun the development of an innovative antifouling protective film for marine applications that is resistant to algae, barnacles and marine growth. The problem ACTI is facing is that during film manufacture, their novel coatings are giving non-uniform dispersion of antimicrobial agent and significant failures due to pinhole defects in the top coat. More importantly, they are motivated to find alternative less-toxic solutions to copper-based coatings necessitating the need for a formulation study investigating several non-copper anti-fouling additives. At Western with the Charpentier group we will evaluate the physical, mechanical and chemical parameters of several different marine coating formulations provided by ACTI. First, several current ACTI films/coatings will be tested to understand baseline properties on thickness, contact angle and mechanical properties. Polymers will be formulated using ACTI proprietary formulations integrating non-Copper additives. Using laboratory lamination and screen printing systems in the Charpentier lab we will evaluate deposition of these polymer systems on backings provided by ACTI. Precise control of the topographical and surface properties will allow us to better understand and control the adhesion and growth of microorganisms and cells to the coating surfaces. Surface energy and hydrophobicity of the coating surface along with anti-fouling will be measured on the various bulk polymer matrices and deposition parameters.

该项目将与 Advanced Converting Technologies (ACTI) 合作，这是一家专注于定制粘合剂涂层和层压工艺的加拿大公司。 ACTI 已开始开发一种适用于海洋应用的创新型防污保护膜，可抵抗藻类、藤壶和海洋生物的生长。 ACTI 面临的问题是，在薄膜制造过程中，其新型涂层导致抗菌剂分散不均匀，并且由于面漆中的针孔缺陷而导致严重失效。更重要的是，他们有动力寻找替代铜基涂料的毒性较小的解决方案，因此需要进行配方研究来调查几种非铜防污添加剂。 在 Western 与 Charpentier 团队合作，我们将评估 ACTI 提供的几种不同船舶涂料配方的物理、机械和化学参数。首先，将测试几种当前的 ACTI 薄膜/涂层，以了解厚度、接触角和机械性能的基线性能。聚合物将使用 ACTI 专有配方结合非铜添加剂进行配制。使用 Charpentier 实验室的实验室层压和丝网印刷系统，我们将评估这些聚合物系统在 ACTI 提供的背衬上的沉积情况。精确控制形貌和表面特性将使我们能够更好地了解和控制微生物和细胞在涂层表面的粘附和生长。涂层表面的表面能和疏水性以及防污性将在各种本体聚合物基质和沉积参数上进行测量。
