PREPARATION METHOD OF GOLD / TITANIUM OXIDE COMPLEX NANOSTRUCTURE USING SELF-ASSEMBLED DIBLOCK COPOLYMERS AND TWO DIMENSIONAL GOLD / TITANIUM OXIDE NANODOT AND NANOWIRE WHICH ARE MANUFACTURED THEREOF, CAPABLE OF ARRANGING GOLD / TITANIUM OXIDE COMPLEX NANO MATERIALS WITHOUT CONVENTIONAL COMPLEX PROCESS

摘要

PURPOSE: A preparation method of gold / titanium oxide complex nanostructure using self-assembled diblock copolymers and two dimensional gold / titanium oxide nanodot and nanowire which are manufactured thereof are provided to manufacture a regular gold / titanium oxide nanodot and an irregular nanowire by controlling a mixing ratio of the self-assembled diblock copolymers, gold nanoparticle, and titanium oxide precursor solution.;CONSTITUTION: A preparation method of two dimensional gold / titanium oxide complex nanostructure comprises the following steps: a step(1 step) manufacturing a micellar solution by dissolving self-assembled copolymers in a solvent; a step(2 step) manufacturing a colloidal solution by dissolving gold nanoparticles in the solvent; a step(3 step) manufacturing titanium oxide sol-gel precursor solution; a step(4 step) manufacturing a thin film of gold nanoparticle / titanium oxide / self-assembly copolymers by spin-coating a mixture on a substrate after mixing the micellar solution, the colloidal solution, and the sol-gel precursor solution in a constant ratio; and a step(5 step) removing the self-assembled copolymers by irradiating ultraviolet ray on the manufactured thin film.;COPYRIGHT KIPO 2010
