描述了在苯基硅氧烷的深紫外图案化自组装单分子膜（SAMs）上制备微图案化TiO2薄膜的方法。将图案化的SAM浸入酸性的TiF62水溶液中，以直接将结晶TiO 2（TiO2）存款到疏水（掩蔽）和亲水（辐照）表面区域上，而不需要沉积后热固化。随后的超声处理选择性地去除存在于疏水区域中的弱结合的TiO 2，从而产生微图案化的TiO 2薄膜。
The fabrication of micropatterned TiO2 films on deep UV patterned self-assembled monolayers (SAMs) of phenylsiloxane is described. The patterned SAM was immersed in an acidic, aqueous TiF62- solution to directly deposit crystalline TiO2 (anatase) onto both hydrophobic (masked) and hydrophilic (irradiated) surface regions without the need for postdeposition heat curing. Subsequent sonication selectively removed weakly bound TiO2 present in the hydrophobic regions, resulting in a micropatterned TiO2 thin film.
