Abstract
A method for forming a self-cleaning coating, comprises providing a first dispersion comprising plasmonic nanoparticles by suspending plasmonic nanoparticles in an organic medium and providing a second dispersion comprising a precursor of a photocatalytic matrix in an organic medium. The method further comprises forming a mixture of the first and second dispersion and coating the mixture on a surface. The method also comprises calcining the coated mixture.
Claims5
A sol-gel method for forming a self-cleaning coating comprising plasmonic nanoparticles dispersed in a photocatalytic matrix, the method comprising:
- a. providing a first dispersion comprising the plasmonic nanoparticles by:
- complexing plasmonic nanoparticles, having a size of from 3 nm to 200 nm, with a stabilizing agent suitable for stabilizing the dispersion of the plasmonic nanoparticles in an organic solvent, by complexing the plasmonic nanoparticles with a first stabilizing agent for stabilizing the plasmonic nanoparticles in an aqueous medium and subsequently exchanging the first stabilizing agent for a second stabilizing agent for stabilizing the plasmonic nanoparticles in an organic medium, and
- suspending the complexed plasmonic nanoparticles in the organic solvent,
- b. providing a second dispersion comprising a precursor of the photocatalytic matrix in an organic medium,
- c. forming a mixture of the first and second dispersion, wherein forming said mixture comprises forming a sol,
- d. coating the mixture on a surface, and
- e. calcining the coated mixture.
