摘要
采用喷涂和旋涂相结合的方法,在干燥洁净的石英基质上制备了均匀的碳纳米管薄膜.利用高分辨透射电子显微镜(JEM-2010 F)对碳纳米管原料的形态进行了观察.利用紫外-可见分光光度计(UV-2550)和四探针电阻测试仪(RTS-8)分别测量了碳纳米管薄膜的透光率和电阻.考察了制备方法、加热温度、碳纳米管浓度和薄膜厚度等不同因素对薄膜透光率和电阻的影响.结果表明,选择适宜的参数可以制备出透明导电的碳纳米管薄膜,且具有良好的电学和光学特性:透光率和电阻分别可以达到83%和800Ω.
The uniform CNTs film was prepared on dry and clean quartz substrate with spray and spin coating technology. The morphology of multiwall CNTs was observed by High Resolution Transmission Electron Microscopy （HRTEM）. The transmittance and resistance of films were tested with UV-Vis Spectrophotometer （UV-2550） and Four Probe Resistance Tester respectively. We then study the effects of preparation method, heating temperature, concentration of CNTs and film thickness on the transmittance and resistance of films. Results show that transparent and conductive CNTs films can be prepared by choosing optimum parameters with good optical and electronic properties; the light transmittance and resistance can reach 83 % and 800Ω respectively.
