Extension of the surface sol-gel process to form molecularly alternate metal oxide/polymer films is reported. The Figure is a schematic illustration of the chemical structure of TiO2/poly(acrylic acid) multilayers grown using this method. It is demonstrated that films can also be assembled using aluminum, zirconium, niobium, and barium titanium alkoxides.
