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

木材通常被认为是一种优质、坚固的材料，但需要定期和细致的维护，这一特性使其在户外应用中不太受欢迎。液体涂料通常用于保护木材免受变质。然而，这些涂料的特点往往是对木材的附着力差，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、尚未探索的方法，用于在大块木材表面生长功能性涂层。这项研究将依赖于使用冷，大气压等离子体控制的电介质屏障。该项目的一个重要成果将是开发一种基于在大气压下操作的低成本等离子体工具的工艺，该工艺具有环保的优点，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的涂料上，并提高木材对紫外线辐射和生物攻击的抵抗力。由于需要广泛的知识来有效地解决与使用大气压等离子体在木材上生长功能性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团队，他们拥有多样化和互补的专业知识。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，而且还可以将他们的研究项目整合到旨在共享知识，基础设施和HQP培训责任的战略中。为了确保这项研究对加拿大和法国的显着利益，我们的团队可以依靠
