TI  - UV/thermally driven rewritable wettability patterns on TiO2-PDMS composite films.

AB  - Composite films of TiO2 and polydimethylsiloxane (PDMS) are prepared by a sol-gel 
      method, cured with UV irradiation, and then treated in hot water to crystallize 
      the TiO2 in the film. The presence of anatase TiO2 contributes to the 
      photoinduced superhydrophilicity of the film under UV irradiation. Contact angle 
      studies reveal that the TiO2-PDMS composite film recovers its original 
      hydrophobic state. Hydrophobic-superhydrophilic patterns are successfully formed 
      on the films. The wettability patterns can be erased by UV irradiation and 
      thermal treatment. New wettability patterns can be reconstructed, demonstrating 
      that the film exhibits rewritable wettability without the need for organic 
      chemicals.
