FABRICATION OF TITANIUM DIOXIDE NANOFIBER CONTAINING ZINC OXIDE NANOPARTICLES USING AN ELECTROSPINNING METHOD AND AN ANTIBACTERICIDAL APPLICATION OF THE SAME UNDER ULTRAVIOLET RAYS AND VISIBLE RAYS OR WITHOUT LIGHT IRRADIATION, CAPABLE OF IMPROVING THE ANTIBACTERICIDAL CAPACITY OF TITANIUM DIOXIDE NANOFIBER CONTAINING ZINC OXIDE NANOPARTICLES

摘要

PURPOSE: Fabrication of titanium dioxide nanofiber containing zinc oxide nanoparticles and an antibactericidal application of the same are provided to easily fabricate titanium dioxide nanofiber containing zinc oxide nanoparticles using a mixed solution of a titanium dioxide precursor, a zinc oxide precursor, and a polymer.;CONSTITUTION: Fabrication of titanium dioxide nanofiber includes the following steps of: preparing the mixed solution of a titanium dioxide precursor, a zinc oxide precursor, polymer, and acetic acid; preparing polymer nanofiber, in which the titanium dioxide precursor and the zinc oxide precursor are mixed, by an electrospinning method; forming titanium dioxide from the titanium dioxide precursor by hydrolysis; and preparing titanium dioxide nanofiber containing zinc oxide nanoparticles by thermally treatment. The sizes of the voltages in the electrospinning method are in a range between 1-60kV. The thermal treatment temperature is in a range between 400-550°C, and the thermal treatment time is in a range between 1 and 4 hours.;COPYRIGHT KIPO 2013
