    摘要: 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. The film system includes a plurality of regions including the photocatalytic material and disposed within the monolayer such that each of the plurality of regions abuts and is surrounded by the fluorocarbon.

    摘要: A self-cleaning film system configured for reducing a visibility of a contaminant includes a substrate and a film. The film includes a monolayer defining a plurality of cavities and formed from a first material having a first surface energy, and a plurality of patches disposed within the plurality of cavities. Each of the patches is formed from a photocatalytic material having a second surface energy that is higher than the first. The film has a touchpoint area having a first use frequency, and a second area having a second use frequency that is less than the first. The patches are present in the touchpoint area in a first concentration and are configured to direct the contaminant towards the second area. The patches are present in the second area in a second concentration that is higher than the first and are configured to reduce the visibility of the contaminant.

    摘要: A self-cleaning film system includes a substrate and a film. The film includes a monolayer formed from fluorinated material and a first plurality of regions disposed within the monolayer and spaced apart from one another such that each of the first plurality of regions abuts, is surrounded by, and is not covered by the fluorinated material. Each of the first regions includes a photocatalytic material. A method of forming a self-cleaning film system includes depositing a monolayer formed from fluorinated material onto a substrate. After depositing, the method includes ablating the monolayer to define a first plurality of cavities therein, wherein each of the first cavities is spaced apart from an adjacent one of the first cavities along the monolayer. After ablating, the method includes embedding a photocatalytic material into each of the first plurality of cavities to form a film on the substrate and thereby form the film system.

    摘要: A method of forming a self-cleaning film system includes depositing a fluorinated material selected from the group consisting of fluorinated organic compounds, fluorinated inorganic compounds, and combinations thereof onto a substrate to form a first layer. The method includes removing a plurality of portions of the first layer to define a plurality of cavities in the first layer and form a plurality of projections that protrude from the substrate. The method includes depositing a photocatalytic material onto the plurality of projections and into the plurality of cavities to form a second layer comprising: a plurality of bonded portions disposed in the plurality of cavities and in contact with the substrate, and a non-bonded portion disposed on the plurality of projections and spaced apart from the substrate. The method also includes, after depositing the photocatalytic material, removing the non-bonded portion to thereby form the self-cleaning film system.
