Greater exploitation of space has fostered research towards the production of highly-performing cheaper satellites of small size and small weight ranging from micro- (10-100 kg) to picosatellites (less than 1 kg). This reduction requires the development of novel smart radiator devices (SRDs) to overcome the present limitations of thermal control systems in terms of mass, surface area and power budget. SRDs based on the thermochromic approach incorporate films of which the thermal emittance passively switches from a high value at high temperature to a low value at low temperature. One of the most promising smart materials for such applications is vanadium oxide (VO2). In this context, we propose an ambitious research project to tackle the challenges associated with the synthesis of smart polycrystalline VO2 thin films on space-compatible substrates using advanced plasma-based processes. This project will cover several aspects spanning from the understanding of the role of dopants on the metal-to-insulator transition temperature and on the emittance of the VO2 films to the fabrication of SRDs prototypes and their performance evaluation in space environment. Because of the wide range of knowledge required to address all the scientific and technological challenges associated to the development of VO2-based SRDs, we have formed a team with Canadian and French researchers that have complementary expertise. The possibility offered by the joint NSERC/ANR program represents a unique opportunity for our team not only to significantly contribute to a domain of strategic interest for both Canada and France, but also to integrate our research 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 major industrial partner (MPBC). This project will help MPBC to position as one of the future world leaders in the manufacturing of the next generation of SRDs. Moreover, our proposal is supported by 3 end users, namely Magellan Aerospace in Canada, and Thales Alenia Space and Airbus Defence & Space in France, who will be able to integrate these VO2-based SRDs in their future products.

对空间的更大开发促进了对生产高性能、低成本、小尺寸和小重量卫星的研究，这些卫星从微型卫星（10-100公斤）到皮卫星（不到1公斤）不等。这种减少需要开发新的智能散热器设备（SRD），以克服目前热控制系统在质量，表面积和功率预算方面的限制。基于热致变色方法的SRD包括膜，其热发射率被动地从高温下的高值切换到低温下的低值。其中一种最有前途的智能材料是氧化钒（VO 2）。在这种情况下，我们提出了一个雄心勃勃的研究项目，以解决与智能多晶VO 2薄膜的空间兼容的基板上使用先进的等离子体为基础的工艺合成相关的挑战。该项目将涵盖几个方面，从了解掺杂剂对金属-绝缘体转变温度和VO 2薄膜发射率的作用，到SRD原型的制造及其在空间环境中的性能评估。由于需要广泛的知识来解决与基于VO 2的SRD的开发相关的所有科学和技术挑战，我们与加拿大和法国的研究人员组成了一个团队，他们具有互补的专业知识。联合NSERC/ANR计划提供的可能性为我们的团队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，还可以将我们的研究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主要工业合作伙伴（MPBC）的支持。该项目将帮助MPBC成为下一代SRD制造的未来世界领导者之一。此外，我们的建议得到了3个最终用户的支持，即加拿大的Magellan Aerospace，法国的Thales Alenia Space和Airbus Defence & Space，他们将能够在未来的产品中集成这些基于VO 2的SRD。
