Zirconia-titania hybrid films with composition gradient along film normal were successfully synthesized with nanometer precision via the surface sol-gel process and low-temperature oxygen plasma treatment. The polymer component was removed by plasma etching from (zirconia/ PAA)(titania/PAA) nanocomposite films to give wormlike random mesopores with diameters of around 2 nm, as confirmed by TEM. The nanogradients of zirconia and titania components were preserved for PAA-hybrid films based on XPS measurement, but it was not the case without PAA.
