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，几乎所有的船舶和船只都含有防污涂层，以防止由于生物污染而导致的性能损失。然而，对这些涂层的环境危害的日益关注已经产生了对保持对船舶的保护的新的生态友好技术的日益增长的需求。为了保护和保持暴露于环境的物体的有效功能，一种可持续的方法是应用表现出疏水性/超疏水性的低表面能表面涂层，例如聚四氟乙烯（PTFE，即PTFE）。Teflon®）。为了保持这些涂层的有效性，需要高性能的粘合剂，可以保持外表面层与物体之间的强粘合力，这些物体可以是金属，商品塑料，玻璃纤维，木材等。保持对PTFE的粘附性是一个巨大且不断增长的技术挑战，缺乏实用和可持续的方法。该项目将产生一种可扩展的工艺，用于合成PTFE的新粘合剂涂层，优化粘合剂用聚合物和配方，以及一套基于最近PCT专利申请的相关IP。这项工作对于一家初创公司a2 o Materials Inc.的发展至关重要。由于海洋市场对新型环保涂料配方的巨大需求，这种涂料配方可以防止生物污染并减少阻力，同时保持无毒，因此将开发用于涂覆和粘附PTFE的APE粘合剂，以应对这一具有挑战性的商业应用。
