Preparation of self-cleaning surfaces with a dual functionality of superhydrophobicity and photocatalytic activity
Abstract(#br)Thin film of polydimethylsiloxane (PDMS) was deposited on SiO 2 nanoparticles by chemical vapor deposition, and SiO 2 became completely hydrophobic after PDMS coating. Mixtures of TiO 2 and PDMS-coated SiO 2 nanoparticles with various relative ratios were prepared, and distributed on glass surfaces, and water contact angles and photocatalytic activities of these surfaces were studied.
