Abstract

The deposition of TiO 2 films on silanized industrial glass surfaces was investigated by XPS. The results show that mercaptopropyltrimethoxysilane was self-assembled on the industrial glass surface and the terminal groups (-SH) were nearer to the air/silane interface than the silicon atoms. Longer treatment of SAMs with hydrogen peroxide in acetic acid can make the conversion of the terminal groups in the top-most layer into desirable sulfonate groups complete. TiO 2 thin films are successfully absorbed on self-assembly monolayers and titanium oxide with different oxidation states may exist in the thin films as-deposited on the surface of the self-assembly monolayers.

      The thiol-containing surface was placed in a 50-mL PTFE beaker containing a solution of 30% H2O2/HOAc (1:5, v/v) maintained at 45 °C. The substrate was withdrawn after 1 h and cleaned with DI water, acetone, and dried by N2 [24,25]. Copper film deposition experiments were carried out in a homemade CVD system that has been described previously [17,18].

      Usually, the terminal functionality can be chemically or photochemically modified to significantly alter the monolayer's chemical composition, reactivity and physical characteristics. Ordered molecular arrangements can be achieved by SAM adsorption even on solid surfaces of random atomic arrangements such as glasses, which provides a great potential for controlled inorganic crystal growth [4,16]. This simple process makes SAMs manufacturable and thus attractive for engineering applications.
