Abstract

This paper demonstrates the utility of an electrodeposition technique to deposit a layer of biodegradable sol-gel derived silica on a Ti substrate coated with a nanoporous TiO₂ layer in a controlled manner. The deposition pattern of the silica phase was tailored by controlling the silica sol content in the diluted solution and the deposition time. This allowed the nanopores to be filled with the silica phase, confirmed by energy dispersive spectroscopy and Fourier-transform infrared spectroscopy, whilst preserving the nanoporous surface, particularly when electrodeposition was carried out in a dilute solution with a silica sol content of 30 vol.% for < 30 min at an electric field of 2.5 V/cm.
