Micropatterning of Titanium Dioxide on Self-Assembled Monolayers Using a Liquid-Phase Deposition Process

Biomimetic Micropatterning of Titanium Dioxide Thin Films for Gate Dielectrics

“…Among a variety of biomimetic synthetic processes, we have concentrated on the utilization of self-assembled monolayers (SAMs) as typical molecular assemblies for micropatterning of oxide thin films via low temperature liquid phase reactions [4][5][6][7]. interfaces.…”

“…We successfully fabricated micropatterned TiO2 films on SAMs of phenyltrichlorosilane (PTCS) using a liquid phase deposition process involving precipitation from aqueous solutions containing ions [4]. In this scheme, PTCS-SAMs were exposed to UV irradiation through a photomask to have a phenyl/silanol-pattern Figure 1 Biomimetic strategy for the fabrication of micropattems.…”

Nanofabrication of Metal Oxide Patterns Using Self-Assembled Monolayers

“…[42][43][44] More recently, Dressick and coworkers demonstrated that solvent accessibility to underlying substrates in aromatic siloxane films is also important [45][46][47] and may be an even greater factor in controlling the properties of those films, which may account for our previous selectivity observation using phenylsiloxane films, as shown in the lift-off process. In the lift-off process 48 , thin films were formed on the entire area of patterned SAM that has silanol group regions and phenyl (or octadecyl) group regions. After being dried, the substrate was sonicated in water to lift off thin films on phenyl (or octadecyl) group regions selectively.…”

“…This resulted in high feature edge acuity of the patterns compared to our previous works. 48 Additionally, the micropattern of thin films was also fabricated by the site-selective immersion method 41 . A solution containing a Ti precursor contacted the hydrophilic regions during the experiment and briefly came into contact with the hydrophobic regions.…”

Electro-photocatalytic degradation of acid orange II using a novel TiO2/ACF photoanode

“…The ACF was pretreated in boiling water for 60 min, air-dried overnight, and then hydroxylated by immersion in 1 M of ammonium peroxydisulfate aqueous solution at 50°C for 60 min. The coating procedure, known as liquid phase deposition (LPD), was adopted from Koumoto et al (1999) and Herbig and Löbmann (2004). In order to test the integrity of the TiO 2 coating, the TiO 2 /ACF so prepared was placed in 100 mL of deionized water in a glass bottle and shaken (side-wide) at 150 rpm for 12 h. The turbidity of the deionized water was then determined with a turbidimeter (HACH 2100N, USA).…”
