Owing to their remarkable properties, single-walled carbon nanotube thin-film transistors (SWCNT-TFTs) are expected to be used in various flexible electronics applications. To fabricate SWCNT channel layers for TFTs, solution-based film formation on a self-assembled monolayer (SAM) covered with amino groups is commonly used. However, this method uses highly oxidized surfaces, which is not suitable for flexible polymeric substrates. In this work, a solution-based SWCNT film fabrication using methoxycarbonyl polyallylamine (Moc-PAA) is reported. The NH -terminated surface of the cross-linked Moc-PAA layer enables the formation of highly dense and uniform SWCNT networks on both rigid and flexible substrates. TFTs that use the fabricated SWCNT thin film exhibited excellent performance with small variations. The presented simple method to access SWCNT thin film accelerates the realization of flexible nanoelectronics.
由于其卓越的性能，单壁碳纳米管薄膜晶体管（SWCNT-TFTs）有望应用于各种柔性电子器件中。为了制造用于TFTs的SWCNT沟道层，通常采用在覆盖有氨基的自组装单分子层（SAM）上进行基于溶液的成膜方法。然而，这种方法使用的是高度氧化的表面，不适用于柔性聚合物基板。在这项工作中，报道了一种使用甲氧基羰基聚烯丙胺（Moc-PAA）进行基于溶液的SWCNT薄膜制备方法。交联的Moc-PAA层的NH端表面能够在刚性和柔性基板上形成高度致密且均匀的SWCNT网络。使用所制备的SWCNT薄膜的TFTs表现出优异的性能，且变化很小。所提出的制备SWCNT薄膜的简单方法加速了柔性纳米电子器件的实现。
