本特許技術では、パルス直流電気泳動を用いて、金属ワイヤー上に酸化チタンナノ粒子膜を均一に形成します。水系または有機系分散媒に変動電圧を加えることで、密着性と光触媒活性に優れた膜を得ることができます。This patented method enables the uniform deposition of titanium oxide nanoparticle films onto metal wires using pulse DC electrophoresis. The technique achieves strong adhesion and high photocatalytic activity by applying fluctuating voltage to aqueous or organic suspensions.
