Photocatalytic degradation efficiencies for the dye droplets of (A) RhB, (B) MB and (C) MO deposited separately on (c) PC coatings, (b) TiO2 @ PC coatings, and (a) E-DA-TiO2 (Ag)@PC coatings under visible light for 30 min (RhB) or1 h (MB and MO), taking (d) the ones in dark as the controls (Insert: the photographs of the dye droplets degraded on the corresponding coatings). (D) The cycling times-depending degradation efficiencies for RhB droplets and hydrophobic performances (CAs) of E-DA-TiO2 (Ag)@PC coatings (insert: the photographs of corresponding water droplets for measuring CAs).
