Abstract

Two-dimensional (2D) RuO2 nanosheets with nanometer thickness were synthesized using a chemical exfoliation method. The synthesized 2D-RuO2 was hybridized with Ag-nanowire (NW), which is attracting attention as a next-generation transparent electrode material. After coating Ag-NW on the substrate, 2D-RuO2 was subsequently coated on the Ag-NW. Although there was a decrease in optical transmittance, the hybridization of 2D-RuO2 confirmed the effect of reducing sheet resistance. Furthermore, the flexibility of the fabricated transparent electrodes was also studied. It was confirmed by the change in sheet resistance after bending. The additional coating of 2D-RuO2 improved the flexibility of the transparent electrodes.

화학적 박리법을 이용하여 나노미터 두께를 갖는 2차원(2D) RuO2 나노시트를 합성하였다. 차세대 투명전극 소재로 주목받고 있는 Ag-nanowire(NW)와 본 연구에서 합성된 2D-RuO2를 하이브리드화하였다. 기판 위에 Ag-NW 코팅 후 2D-RuO2를 추가로 코팅하였다. 광투과도의 감소는 있었지만 2D-RuO2를 하이브리드화하여 면저항 감소 효과를 확인할 수 있었다. 또한 제조된 투명전극의 유연성 실험도 진행하였다. 벤딩 후 면저항 변화로 확인하였다. 2D-RuO2의 추가 코팅으로 투명전극 유연성이 향상되었다.
