Abstract
A method of forming a self-cleaning film system includes ink jet printing a composition onto a substrate. The composition includes an oleophobic material and a photocatalytic material. The method further includes curing the composition to form a self-cleaning film disposed on the substrate and thereby form the self-cleaning film system. The self-cleaning film includes a first plurality of regions including the photocatalytic material and disposed within the oleophobic material such that each of the first plurality of regions abuts and is surrounded by the oleophobic material.
Claims22
A method of forming a self-cleaning film system, the method comprising:
- ink jet printing a composition onto a substrate, wherein the composition includes:
- an oleophobic material;
- and
- a photocatalytic material;
- and
- curing the composition to form a self-cleaning film disposed on the substrate and thereby form the self-cleaning film system;
- wherein the self-cleaning film includes a first plurality of regions including the photocatalytic material and disposed within the oleophobic material such that each of the first plurality of regions abuts and is surrounded by the oleophobic material.
A method of forming a self-cleaning film system, the method comprising:
- disposing a sol-gel material onto a substrate;
- hydrolyzing and condensing the sol-gel material to chemically bond an adhesion layer to the substrate;
- after disposing, depositing a composition onto the adhesion layer, wherein the composition includes:
- an oleophobic material;
- and
- a photocatalytic material;
- and
- curing the composition to form a self-cleaning film disposed on the adhesion layer and thereby form the self-cleaning film system;
- wherein the self-cleaning film includes a first plurality of regions including the photocatalytic material and disposed within the oleophobic material such that each of the first plurality of regions abuts and is surrounded by the oleophobic material;
- and
- wherein the photocatalytic material is physically trapped by the adhesion layer.
A method of forming a self-cleaning film system, the method comprising:
- disposing an upconversion layer formed from an luminescent material onto a substrate, wherein the upconversion layer is configured for converting a first electromagnetic radiation having a wavelength of from 490 nm to 450 nm to a second electromagnetic radiation having an ultraviolet wavelength of from 10 nm to 400 nm;
- after disposing, depositing a composition onto the upconversion layer, wherein the composition includes:
- an oleophobic material;
- and
- a photocatalytic material;
- and
- curing the composition to form a self-cleaning film disposed on the upconversion layer and thereby form the self-cleaning film system;
- wherein the self-cleaning film includes a first plurality of regions including the photocatalytic material and disposed within the oleophobic material such that each of the first plurality of regions abuts and is surrounded by the oleophobic material.
