摘      要：The widely used photocatalytic self-cleaning coating materials are often made of polymers and polymer based composites,where the photocatalyst immobilization occurs with ***,these organic polymers are often unstable under exposure to UV irradiation and easily degraded by reactive radicals produced in the photocatalytic *** order to solve this problem,in this paper,we present the facile preparation of a multifunctional coating with dual superhydrophobic and photocatalytic properties,where the fixation and the hydrophobization of the plasmonic Ag-TiO2 photocatalyst particles with visible light activity was performed with non-water soluble sulfur,which is a cheap and easily available *** resulted novel nanocomposite with rough and nano-tructured surface roughness(1.25–2.45 nm determined by small-angle X-ray scattering)has sufficient low surface energy(3.3 mJ/m2)for superhydrophobic(θ=151.1°v)***,in contrast of the organic and expensive fluoropolymer based composites,this non-wetting nature was durable,because the measured was higher than 150°during the long-term LED(λmax=405 nm)light irradiation.
