    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 plurality of regions disposed within the monolayer such that each of the plurality of regions abuts and is surrounded by the fluorinated material and includes a photocatalytic material. The system includes an adhesive layer adhered to the substrate and a release liner affixed to and removable from the adhesive layer.

    Abstract: A film system includes a substrate and a film disposed on the substrate. The film includes a monolayer formed from a fluorocarbon and a plurality of regions disposed within the monolayer such that each of the plurality of regions abuts and is surrounded by the fluorocarbon. Each of the plurality of regions includes a photocatalytic material. A method of forming a film system includes depositing a monolayer formed from a fluorocarbon onto a substrate. After depositing, the method includes ablating the monolayer to define a plurality of cavities therein, wherein each of the plurality of cavities is spaced apart from an adjacent one of the plurality of cavities along the monolayer. After ablating, the method includes embedding a photocatalytic material into each of the plurality of cavities to form a film on the substrate and thereby form the film system.
