In marine engineering, virtually all ships and vessels contain an anti-fouling coating to prevent loss in performance due to bio-fouling. However, growing concerns over the environmental hazards of these coatings have created a growing demand for new eco-friendly technologies which maintain protection of the vessel. To protect and preserve the efficient function of objects exposed to the environment, a sustainable approach is the application of low surface energy surface coatings that exhibit hydrophobicity/superhydrophobicity, such as poly(tetrafluorethylene) (PTFE, ie. Teflon®). To maintain the effectiveness of these coatings, high-performance adhesives are required which can maintain strong adhesion between the outer surface-layer with the object, which can be metal, commodity plastic, fibre-glass, wood, etc. This project will develop adhesive materials featuring recently developed novel amine-functionalized polyethylene (APE) as adhesives for the application of low-surface energy top-coats of PTFE. Maintaining adhesion to PTFE is a large and ever-growing technical challenge that lacks practical and sustainable approaches. This project will result in a scalable process for the synthesis of new adhesive coatings for PTFE, optimized polymers and formulations for adhesive use and a suite of related IP that builds upon recent PCT patent applications. This work is critical to the advance a start-up company, a2o Materials Inc. Owing to the enormous demand in the marine market for new eco-friendly coating formulations that prevent bio-fouling and reduce drag all while remaining non-toxic, the APE adhesive for coating and adhering PTFE will be developed for this challenging commercial application.

在海洋工程中，几乎所有船舶都含有防污涂层，以防止因生物污损而导致性能下降。然而，人们对这些涂层的环境危害的日益关注，对新的环保技术的需求不断增长。为了保护和保持暴露在环境中的物体的有效功能，一种可持续的方法是应用具有疏水性/超疏水性的​​低表面能表面涂层，例如聚四氟乙烯（PTFE，即聚四氟乙烯）。为了保持这些涂层的有效性，需要高性能粘合剂，以保持外表面层与物体（可以是金属、商品塑料、玻璃纤维、木材等）之间的牢固粘附力。该项目将开发以最近开发的新型胺官能化聚乙烯 (APE) 为粘合剂的粘合剂材料，用于 PTFE 低表面能面漆的应用，保持对 PTFE 的粘合力是一项巨大且不断增长的技术挑战。该项目将产生一种可扩展的合成新 PTFE 粘合剂涂层的工艺、用于粘合剂用途的优化聚合物和配方以及基于最近的 PCT 专利申请的一套相关知识产权。这项工作对于成立了一家初创公司，a2o Materials Inc.。由于海洋市场对新型环保涂料配方的巨大需求，这种配方可以防止生物污垢并减少阻力，同时保持无毒，因此使用 APE 粘合剂进行涂层和粘合PTFE 将针对这一具有挑战性的商业应用而开发。
