Composite materials have been synthesized by levigating TiO2 with polyethylene(PE) [4] or nylon(NL) [5] as substrate.
On the basis of these porous materials, attaching nano-sized inorganic particles to the porous materials is expected to generate a novel composite material with unique properties [10-11].
