Abstract

Layer-by-layer (LBL) self-assembly method was used to fabricate siliceous ultrathin films by using polyhedral oligomeric silsesquioxanes as building blocks. Ammonium salt of octasilsesquioxane acid (OSi₈) and poly(diallyldimethylammonium chloride) (PDDA) were alternately assembled onto CaF₂ slide to form nanocomposite multilayers. Linear build-up of the LBL films was confirmed by UV-Vis spectroscopy. IR spectrum suggests existence of OSi₈ and PDDA in the LBL films. Atomic force microscopic surface topography of the LBL films indicates the OSi₈ covers the entire surface of the topmost layer and shows a granular morphology.
