Characterization of an industrial plasma process to treat fluoropolymers and polyethylene terephthalate for the solar energy industry

近年来，世界各国纷纷提出了绿色减排战略， 签署重要条约，如巴黎协定。基本上，这些协议侧重于两个主要方面， 可能导致二氧化碳产量大幅下降的载体。一方面，许多努力是针对 最大限度地减少能源消耗，另一方面，更环保的能源生产 设施得到发展。正是在这种背景下，圣戈班加拿大公司。开发了一种聚合物薄膜， 应用于房屋和建筑物窗户表面。从本质上讲，这项技术利用了 聚对苯二甲酸乙二醇酯（PET），其高度吸收UV光。一旦安装在窗户上，这种聚合物 薄膜捕捉热量并将其引导回房间，从而在较冷的月份提高整体舒适度， 同时降低能源使用并帮助节约能源。在温暖的月份，它将太阳热量反射到 窗户，减少内部冷却的需求和成本。然而，与大多数聚合物一样，PET不是特别理想的聚合物。 好的候选人时，来的时候，使层压板出来，或打印油墨的各种它，因为它的 低表面能圣戈班还致力于开发能够实现高效组装的材料， 光伏器件，以最大限度地提高太阳能转换的产量。该战略将利用 氟化聚合物在整个紫外和可见光谱范围内的低吸收率。一旦应用于 在光伏器件的顶部，由氟化聚合物制成的薄膜能够保护硅基器件 同时使通过聚合物膜的光能损失最小化。这限制 对太阳能发电造成的损失进行必要的装置保护。不幸的是，使用 用于目标应用的氟化聚合物受限于它们的差的相容性， 把它们粘到任何设备上因此，本项目的目标将是表征工业等离子体 PET和含氟聚合物的表面改性工艺，因此能够将它们与任何其他材料组装在一起。 材料.

The green gas reduction strategies put forward by many countries all over the world recently led to the signatures of major treaties, such as the Paris agreement. Basically, these agreements focus on the two main vectors that may drastically lead to a decrease in CO2 production. On one hand, much efforts are directed to minimizing energy consumption while, on the other hand, more environmentally friendly energy production facilities are developed. It is in this context that Saint-Gobain Canada Inc. developed a polymer thin film to be applied on the surface of house and building windows. Essentially, this technology takes advantage of polyethylene terephthalate (PET), which highly absorbs UV light. Once installed on windows, this polymer film captures heat and directs it back into the room, thus improving overall comfort during cooler months, while lowering energy use and helping to save energy. In warmer months, it reflects solar heat away from windows, reducing the need and cost for interior cooling. However, as most polymers, PET is not particularly a good candidate when comes the time to make laminates out of it or to print inks of all kinds on it, because of its low surface energy. Saint-Gobain also seeks to develop materials that will enable buildind-up efficient photovoltaic devices to maximize the yield of solar energy conversion.The strategy will take advantage of the low absorptivity of fluorinated polymers throughout the whole UV and visible spectral range. Once applied on top of photovoltaic devices, thin films made of fluorinated polymers enable to protect the silicon-based devices against environmental conditions while minimizing the light energy loss through the polymer films. This limits the loss of solar energy production caused by the necessary device protection. Unfortunately, the use of fluorinated polymers for the targeted application is limited by their poor adhesiveness when comes the time to glue them to any devices. Accordingly, the objective of this project will be to characterize an industrial plasma process to modify the surface of PET and fluoropolymers, therefore enabling assembling them with any other materials.
