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 2 ‐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.
