Session 3: Functional and Smart Coatings
The photocatalytic coating provides useful functionalities with a self-cleaning behavior and an organic pollution decomposing ability for many areas to avoid a dirty surface of contamination from the environment. However, the application of the photocatalytic coating for the online coil system is not prevailed to the present-day industrial coating. In this paper, we have developed a self-cleaning coating containing a top photoactive layer and an intermediate layer which enables to fulfill a better weathering performance. Such conspicuous improvement may arise from an excellent flexibility of the inorganic intermediate layer. And this is also demonstrated from a coated substrate that was treated at 260℃ for 45 seconds and cooled down to the ambient temperature back and forth for 3 times. The hydrophilic behavior and the decomposing ability were investigated by exposing a coated substrate to a heavy polluted industrial area. Besides, owing to the design of dual layers, a long-term weathering resistance was achieved by the experimental exposure of the QUV machine and the outdoor environment. This prominent self-cleaning coating may find a unique application for the coil industry of the exterior architectural domain.
