An integrated approach to preparing a hybrid electrochemical sol using precursor tetrabutyl titanate and siliane coupling agents methyltriethoxysilane (MTES), gamma-chloropropyltriethoxysilane (CPTS), N-octyltriethoxysilane (OTEOS) or dodecyltriethoxysilane (DTEOS) was investigated. The functional TiO2 and hydrophobic chain in hybrid electrochemical sol were deposited on cellulose substrate via sol-gel electrochemical deposition to present sensitive superhydrophobic-superhydrophilic smart converting performance. By doping 2% silane coupling agent in hybrid electrochemical sol and depositing at applied voltage 13 V for 8.0 min, the cellulose substrate showed excellent superhydrophobicity. The contact angle reached to 166.1 degrees with OTEOS/TiO2 hybrid sol. During washing process, the contact angle of coated cellulose substrate declined to 161.3 degrees, and decreased to about 119.1 degrees after washing 10 times, which showed excellent washing durability for sol-gel electrochemical deposition. The contact angle was decreased to 0 during 10(5)mu W/cm(2) ultraviolet (UV) for 11.0 min, which was caused by the photoinduced TiO2 component, and the contact angle of the irradiated cellulose substrate recovered gradually in dark environment. When stored in the dark for 40 h, the contact angle could increase to 150.6 degrees, and the fabric recovered to superhydrophobicity. (C) 2015 Elsevier B.V. All rights reserved.
