Development of anti-fog and anti-icing coating by plasma on PET films for helmet visor applications

Fogging and icing of surfaces is an issue that abords applications as diverse as the medical, the automotive, or the photovoltaic field. Even, it can represent a risk when present lenses and windshields, it dangerously reduces the field of view for the user. To address this problem, surface treatments based on coatings and chemical modifications of the surface have been developed. However, they present some drawbacks including the use of hazardous reagents, production of harmful residual products, and lose of properties. This project intends to employ atmospheric pressure plasma treatments for the synthesis of transparent anti-fog/ice coating on polyethylene terephthalate (PET) for helmet visor applications for the Canadian company KIMPEX Canada Inc.. Plasma approach reduces the use of chemical products while PET with anti-fog/ice properties can be easily sticked over lenses and windshields avoiding the treatment of the material of interest, then reducing the cost of treatment, making it removable and remaining transparent.
