Abstract
A self-cleaning film system includes a substrate and a self-cleaning film disposed on the substrate. The self-cleaning film includes a monolayer formed from an oleophobic material, and a first plurality of regions disposed within the monolayer in a non-periodic pattern such that each of the first plurality of regions abuts and is surrounded by the oleophobic material. Each of the first plurality of regions includes a photocatalytic material.
