ANR - Development of functional, nanostructured coatings on wood surfaces using cold, atmospheric-pressure plasmas

木材通常被认为是一种精细、坚固的材料，但它需要定期和细致的维护，这一特点使其在户外应用时不那么受欢迎。液体涂料通常用来保护木材不变质。然而，这些涂料的特点是对木材的附着力很差，而且通常含有有毒溶剂。在这项研究中，我们建议开发一种替代的、但尚未探索的方法，用于在散装木材表面生长功能涂层。这项研究将依赖于使用由介电阻挡层控制的冷的大气压等离子体。该项目的一个重要成果将是开发一种基于在常压下运行的低成本等离子工具的工艺，该工艺具有环保的优势，同时提供高产量和可沉积涂层的广泛灵活性。重点将放在提供超疏水木材表面并提高木材对紫外线辐射和生物攻击的耐受性的涂料上。由于需要广泛的知识来有效地解决与使用常压等离子体在木材上生长功能涂层相关的所有挑战，我们与加拿大和法国的研究人员组成了一个拥有不同和互补的专业知识的团队。因此，NSERC/ANR联合计划提供的可能性为团队成员提供了一个独特的机会，不仅可以为加拿大和法国的战略利益领域做出重大贡献，还可以将他们的研究项目整合到旨在共享HQP培训的知识、基础设施和责任的战略中。为了确保这项研究对加拿大和法国有显著的好处，我们的团队可以依靠一个

Wood is usually considered a fine, strong material, but one that requires regular and meticulous maintenance, a characteristic that makes it less desirable when marketed for outdoor applications. Liquid coatings are routinely used to protect wood against deterioration. However, these coatings are often characterized by poor adhesion on wood and usually imply toxic solvents. In this research, we propose to develop an alternative, yet unexplored approach for the growth of functional coatings on bulk, wood surfaces. This research will rely on the use of cold, atmospheric-pressure plasmas controlled by dielectric barriers. An important outcome of this project will be the development of a process based on a low-cost plasma tool operated at atmospheric pressure that has the advantage of being eco-friendly while offering high throughputs and a broad flexibility in terms of coatings that can be deposited. The emphasis will be put on coatings that provide superhydrophobic wood surfaces and that improve the resistance of wood to UV radiation and biological attacks. Because of the wide range of knowledge required to address efficiently all the challenges associated to the growth of functional coatings on wood using atmospheric-pressure plasmas, we have formed a team with Canadian and French researchers that have diverse and complementary expertises. The possibility offered by the joint NSERC/ANR program thus represents a unique opportunity for the team members not only to provide a significant contribution to a domain of strategic interest for both Canada and France, but also to integrate their research project in a strategy aiming at sharing knowledge, infrastructure, and responsibilities of HQP training. To ensure a remarkable benefit of this research to Canada and France, our team can rely on the support of a
