탄소나노튜브-금속산화물 나노와이어의 3차원 혼성 나노구조 형성 및 응용

We present the assembly and application of three-dimensional (3D) hybrid nanoarchitectures comprising carbon nanotubes (CNTs) and metal oxide (MOx) nanowires such as zinc oxide and vanadium oxide. The MOx nanowires are hierarchically assembled onto the surface of aligned or textured CNT constructs via the step-wise chemical vapor deposition (CVD) process at the temperature CNTs are free from oxidative degradation. Since the conformal highdensity MOx nanowires can be directly connected to highly conducting CNT framework over large interfacial area, the electrical response originating from functional MOx upon external stimuli can be rapidly and efficiently collected through the CNT framework, leading to many applications ranging from fast-responsive sensors to energy converters.
