TIO2 NANOTUBES FILLED WITH LEAD ACETATE, A METHOD FOR FILLING TIO2 NANOTUBES WITH LEAD ACETATE AND A METHOD FOR MANUFACTURING FERROELECTRIC NANOTUBE ARRAYS

摘要

PURPOSE: A method to fill lead acetate in a titanium dioxide(TiO2) nanotube is provided to easily fill the lead acetate into the TiO2 nanotube by immersing the TiO2 nanotube which is self-aligned into a lead acetate solution, or by dropping the lead acetate solution on the TiO2 nanotube. CONSTITUTION: A TiO2 nanotube(300) filled with lead acetate inside is composed of the TiO2 nanotube and the lead acetate. The TiO2 nanotube grows vertically by being anodized on a titanium(Ti) sheet(110). A lead acetate filling method includes a step of dropping a lead acetate solution on the TiO2 nanotube, and drying the TiO2 nanotube. A ferroelectric nanotube element manufacturing method includes following steps; the anodized TiO2 nanotube is prepared; the lead acetate is filled in the TiO2 nanotube; and a lead titanate nanotube is formed by depositing PbO on the TiO2 nanotube filled with the lead acetate.
