A rapid and convenient method was described in this work for creating a nanotextured surface involving the microwave-assisted hydrothermal treatments of polymer films coated on surfaces. The procedure transforms the polymer film into uniform nanotextured islands. The regularly shaped, nanometer-sized polymer islands were utilized as a template for deposition of the metal oxide by spin-coating the metal oxide sol-gel precursor on the polymer nanotextured surface and generating regularly shaped, hollow metal oxide nanostructures after the removal of the polymer template.
