초록
리튬 이온을 기반으로 하는 전해질에서 작동할 수 있는 니켈 산화물 박막을 sol-gel법으로 제조 하여 박막의 고유한 구조를 분석하고 전기변색 특성을 연구하였다. 이 박막은 DmaeH와 물의 부피 비율을 조절한 용매와 니켈 산화물을 녹인 용액을 dip-coating법으로 ITO glass위에 증착 하는 방법으로 제조되었다. 각각의 샘플은 DmaeH와 물의 부피 비율에 따라서 다른 점도와 밀 도, 두께를 가지게 되어 전하량과 광투과도(transmittance)의 변화에 차이를 보였는데, 그 중 1 : 1의 비율을 가진 졸을 이용하여 만든 박막이 가장 두껍지만 porous한 구조를 가져서, 리튬 기반의 전해질에서 뛰어난 전기변색 특성을 보였음을 확인해 볼 수 있었다.
Abstract
In this study, we fabricated nickel oxide thin film for lithium based electrolyte using sol-gel method. This film was deposited by dip-coating method with mixed solvent of DameH (N,N-dimethylaminoethanol) and DI water. As changing the ratio between DmaeH and DI water, nickel oxide thin film was presented in different charge density and optical transmittance because they were shown various thickness. It was accounted for changing viscosity and density by the ratio of DmaeH and DI water. The thin film synthesized with 1 : 1 ratio of DmaeH and DI water was expressed best electrochromic performance in lithium based electrolyte, because of thick thickness but porous structures.
