We report the direct and dry deposition of transparent conducting films (TCFs) of aerosol-synthesized single-walled carbon nanotubes (SWNTs) using a thermophoretic precipitator (TP) designed for the uniform and efficient deposition of aerosol-synthesized nanomaterials on 50 mm wafers or similarly sized polymer substrates. The optical and electrical performance of the fabricated TCFs match or surpass the published results achieved using a filter-based collection of aerosol-synthesized SWNTs, and TCFs with sheet resistances of 60 Ω/sq. at 87.8% transmittance and 199 Ω/sq. at 96% transmittance on flexible polymer substrates are demonstrated. The precipitator design is immediately applicable in roll-to-roll fabrication of SWNT TCFs or other functional coatings of aerosol-synthesized nanomaterials.
我们报道了使用一种热泳沉淀器（TP）对气溶胶合成的单壁碳纳米管（SWNTs）进行透明导电薄膜（TCFs）的直接干法沉积。该热泳沉淀器专为将气溶胶合成的纳米材料均匀且高效地沉积在50毫米晶圆或尺寸类似的聚合物基板上而设计。所制备的TCFs的光学和电学性能与基于过滤器收集气溶胶合成的SWNTs所获得的已发表结果相当或更优，并且展示了在柔性聚合物基板上具有87.8%透光率时方阻为60 Ω/sq以及96%透光率时方阻为199 Ω/sq的TCFs。该沉淀器设计可立即应用于SWNT TCFs的卷对卷制造或气溶胶合成纳米材料的其他功能涂层。
