摘要：The reversible photocontrol of wood-surface wettability between superhydrophilicity and superhydrophobicity based on a TiO2 film modified with octadecyl trichlorosilane (OTS) was achieved via a facile hydrothermal method at low temperature. Under UV illumination, the wood surface became superhydrophilic with a water contact angle (WCA) of approximately 0°. However, when placed in the dark, a superhydrophobic wood surface with a WCA of approximately 152° was achieved. The mechanism of the reversible photocontrol of wood-surface wettability is discussed in this article. This photocontrolled wood surface may have potential for wood self-cleaning or manipulation in response to indoor humidity. Copyright ? Taylor & Francis Group, LLC.
