Self-cleaning superhydrophobic coatings based on PDMS and TiO2/SiO2 nanoparticles

Superhydrophobic coatings based on PDMS and TiO2-NPs/SiO2-NPs were prepared. Due to the photocatalytic property of TiO2-NPs, the PDMS/TiO2-NPs coatings could remove the organic pollutes efficiently, and showed an excellent self-cleaning properties. The superhydrophobicity of the PDMS/TiO2-NPs coatings was still remained after 6months in the open air, which is much better than the PDMS/SiO2-NPs coatings.
