Abstract:
A self-cleaning film system includes a substrate and an anti-reflection film disposed on the substrate. The anti-reflection film includes a first sheet formed from titanium dioxide, a second sheet formed from silicon dioxide and disposed on the first sheet, and a third sheet formed from titanium dioxide and disposed on the second sheet. The system includes a self-cleaning film disposed on the anti-reflection film and including a monolayer disposed on the third sheet and formed from a fluorinated material selected from the group consisting of fluorinated organic compounds, fluorinated inorganic compounds, and combinations thereof. The self-cleaning film includes a first plurality of regions disposed within the monolayer such that each of the first plurality of regions abuts and is surrounded by the fluorinated material and includes a photocatalytic material.
