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.
