Coating formulations of proprietary amine-functionalized polyethylene combined with polytetrafluoroethylene towards formation of eco-friendly high-performance marine coatings

在海洋工程中，几乎所有的船舶和船舶都包含一层防污涂层，以防止由于生物污垢而造成的性能损失。然而，对这些涂料的环境危害的日益关注，产生了对新的环保技术的日益增长的需求，以保持对船舶的保护。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)。特氟龙®)。为了保持这些涂层的有效性，需要高性能的粘合剂来保持外表面层与物体之间的牢固粘合，物体可以是金属、商品塑料、玻璃纤维、木材等。该项目将开发以最近开发的新型胺功能化聚乙烯(APE)为粘合剂的粘合剂，用于低表面能聚四氟乙烯(PTFE)面层。保持对聚四氟乙烯的粘附性是一项巨大的、不断增长的技术挑战，缺乏实用和可持续的办法。该项目将产生一种可扩展的工艺，用于合成用于聚四氟乙烯的新型胶粘剂涂料、用于胶粘剂用途的优化聚合物和配方以及基于最近PCT专利申请的一套相关知识产权。这项工作对初创公司a2o材料公司的发展至关重要。由于海洋市场对新的环保涂料配方的巨大需求，这些涂料配方可以防止生物污染和减少阻力，同时保持无毒，用于涂层和粘接聚四氟乙烯的APE粘合剂将为这一具有挑战性的商业应用而开发。

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.
