Paper Abstract

The surface structures of Coscinodiscus granii frustules were investigated before and after liquid phase deposition (LPD) treatment. Scanning electron microscopy (SEM) images showed that the outer surface of the frustules was rapidly covered with a TiO2 layer within 6 h although the inner surface was not fully covered under the same condition. Comparison between the un-coated samples and the samples coated with metal prior to SEM observation provided valuable results to facilitate the understanding of the differences between the surface properties of the inner and outer frustule structures. Additionally, useful topographical information about the inner frustule surfaces was obtained by AFM imaging. The results of this investigation provide fundamental information about the process of LPD treatment onto frustule surfaces.
