Abstract

A novel ABA-type triblock copolymer, i.e. poly(oxyethylene methacrylate)-b-polystyrene-b-poly(oxyethylene methacrylate) (POEM-b-PS-b-POEM) was synthesized via atom transfer radical polymerization (ATRP). This amphiphilic triblock copolymer was used to template the growth of TiO₂ from a titanium isopropoxide through sol-gel process in the solid state film. The hydrophilic titania precursor was selectively incorporated into hydrophilic POEM domains and formed TiO₂ nanoparticle arrays, mostly due to microphase separation between the PS domains and the POEM/TiO₂ domains. High-density arrays of TiO₂ nanoparticles with 30-40 nm size after calcinations at 550 °C were confirmed by X-ray photoelectron spectroscopy (XPS), UV-vis spectroscopy, wide angle X-ray scattering (WAXS) and transmission electron microscopy (TEM). The resultant TiO₂ nanoparticles showed high photocatalytic activity on the photodegradation of humic acid.
