Deposition of Nanocrystalline Tin (IV) Oxide Films on Organic Self-Assembled Monolayers

ABSTRACTNanocrystalline thin films of tin (IV) oxide (cassiterite) have been deposited from aqueous solutions of tin (IV) chloride and hydrochloric acid at 80°C. Substrates were {100} single-crystal silicon wafers, with and without silanol-anchored, sulfonate-terminated organic self-assembled monolayers (SAMs). Using flowing solutions, films with thicknesses of up to 1 μtm have been grown, whereas the thickness of the films from static solutions is limited to about 80 nm. The films were characterized using transmission electron microscopy and Rutherford backscattering spectroscopy. The role of the flow rate and configuration of the deposition chamber is discussed.

AbstractIn recent years, several research groups have pursued biomimetic or bio-inspired techniques for the synthesis of ceramic thin films from aqueous solutions at low temperatures. The substrates range from inorganic materials (metals, glass, single-crystal silicon) without special surface preparation, to functionalized organic surfaces such as self-assembled organic monolayers (SAMs). Our results on the deposition of tin (IV) oxide (SnO2, cassiterite) and hydroxyapatite (Ca10(PO4)6(OH)2) thin films on SAMs will be reviewed. The former system forms films via assembly of nano-scale particles on the substrate, while the latter system appears to form films via heterogeneous nucleation. In both cases, the role of the substrate in film formation is discussed.

Aldehyde Groups

Self-assembled composite films of APTES-GA-APTES were successfully prepared on single-crystal silicon substrates through the cross-linking reaction between glutaraldehyde (GA) and two layers of 3-aminopropyltriethoxysilane (APTES). The optimal time to deposit the GA layer on the APTES monolayer was 3 h, during which most amino groups of APTES reacted with the aldehyde groups of GA to form smooth and uniform APTES-GA composite films. The further deposition of another APTES layer led to the generation of three-layer APTES-GA-APTES composite films. Compared to the APTES self-assembled monolayers, the three-layer films displayed a similar surface morphology but a reduced friction coefficient from 0.23 to 0.15 and an extended wear life from 50 s to 820 s due to the introduction of GA.
