Effects of ozone nanobubles on superior electric storage for anodically oxidized films of Ti-Ni-Si amorphous alloy ribbons

摘要

Abstract The effects of nanometer-sized bubbles (NBs) of ozone on a superior electric storage capacitor for anodically oxidized films of Ti-15at.% Ni-15at.% Si amorphous alloys were determined in 0.4M H2SO4 solutions with NBs of oxygen and ozone. The Use of ozone NBs accelerates the formation of oxide films at lower than 10V, resulting in uneven surfaces with cavities of 2–10nm in size. The resulting film shows a nearly vertical line in a Nyquist diagram, rapid increases in the imaginary impedance, and a horizontal line near the ?90° phase angle in a Bode diagram, demonstrating evidence for use in an electric distributed constant circuit. Further enhancement of the imaginary impedance for the realization of a superior electric storage capacitor is needed. Highlights ? Effects of oxygen and ozone NBs on anodic oxidization of Ti-based amorphous alloys. ? The use of water with ozone NBs accelerates the formation of oxide films at 10V. ? The film demonstrated evidence for use in an electric distributed constant circuit. ? We evaluate imaginary impedance for realization of superior capacitor. ? We report evidences of series-RC circuit which is necessary for supercapacitors. ]]>
