Recent Advances in TiO2‐Based Nanostructured Surfaces with Controllable Wettability and Adhesion

Bioinspired surfaces with special wettability and adhesion have attracted great interest in both fundamental research and industry applications. Various kinds of special wetting surfaces have been constructed by adjusting the topographical structure and chemical composition. Here, recent progress of the artificial superhydrophobic surfaces with high contrast in solid/liquid adhesion has been reviewed, with a focus on the bioinspired construction and applications of one‐dimensional (1D) TiO 2 ‐based surfaces. In addition, the significant applications related to artificial super‐wetting/antiwetting TiO 2 ‐based structure surfaces with controllable adhesion are summarized, e.g., self‐cleaning, friction reduction, anti‐fogging/icing, microfluidic manipulation, fog/water collection, oil/water separation, anti‐bioadhesion, and micro‐templates for patterning. Finally, the current challenges and future prospects of this renascent and rapidly developing field, especially with regard to 1D TiO 2 ‐based surfaces with special wettability and adhesion, are proposed and discussed.
