Abstract

It was investigated to use the mixture of solvents with different evaporation rates for spray deposition of high uniform CNT films on flexible polymer substrates and substrates with a height differences about 2 micron, near which the formation of nonuniformities is possible when using non-optimal solution composition. The degree of uniformity was estimated by analysis of the surface distribution of the Raman peaks intensity corresponding to CNT. It was shown, in this way, that uniformity was significantly depend which solvent for CNT solution had been used, especially for substrate with patterned structures. In addition, a significant change of resistivity and intensity of Raman scattering of CNT in films was observed after formic acid treatment due to the removal of residual solvent. The obtained results can be used for development of transparent conducting electrodes for organic photovoltaic cells, sensor and autoemission structures.

高均匀碳纳米管薄膜在具有高差的图案结构衬底上的喷射沉积

研究了不同蒸发速率的溶剂混合物在柔性聚合物基片和高度差约2微米的基片上喷雾沉积高均匀碳纳米管薄膜，当使用非最佳溶液组成时，在高度差约2微米附近可能形成不均匀性。通过分析碳纳米管对应的拉曼峰强度的表面分布来估计均匀度。结果表明，均匀性在很大程度上取决于碳纳米管溶液所使用的溶剂，特别是对于具有图案结构的衬底。此外，甲酸处理后，由于去除残留溶剂，碳纳米管薄膜的电阻率和拉曼散射强度发生了显著变化。所得结果可用于开发用于有机光伏电池、传感器和自发射结构的透明导电电极。
