초록

티타니아 나노튜브(Titania nanotube, TNT)는 티타늄을 $F^-$ 이온을 함유한 전해질 하에서 전기로 양극산화 시켜 제조 한 튜브형태의 박막으로 광학 활성을 가진다. 전해질은 증류수와 포름아마이드를 용매로 사용하였으며 HF, NaF, $NH_4F$$F^-$이온 성분으로 사용하였다. 전압과 양극산화 시간이 증가함에 따라 TNT의 길이와 직경도 증가하였다. 양극산화에 의해 제조된 TNT는 매우 규칙적인 튜브형태였으며, 제조 조건에 따라 길이는 최대 13.7 ${\mu}m$이었다. 생성된 티타니아는 비정질이었으며 열처리에 의해 아나타제 결정으로 바뀌었다.

Titania nanotube(TNT), which is a tube shaped thin film manufactured by anodizing titanium under $F^-$ ion electrolyte, has photo activity. Distilled water and formamide were used as solvent, and HF, NaF, $NH_4F$ were used as main $F^-$ ions for the electrolyte. The length and the diameter of TNT increased as the voltage and anodizing time increased. TNT prepared by anodizing was a very ordered tube, and had a maximum length of 13.7 ${\mu}m$ depending on the conditions of manufacturing. Titania prepared by anodizing was amorphous, and became an anatase crystal after heat treatment.
