The non-covalent functionalization of single-walled carbon nanotubes (SWNTs) with conjugated polymers (CPs) improves the processability of SWNTs, enables solution processing due to selective distribution, and makes them a promising material in a various electronic application such as transistors and sensors. However, CPs wrapped CNTs still have a limitation that is the stability and reliability of the CNT films. Here, we propose a method of growth and immobilizing on a substrate using a Click reaction to improve the reliability and stability of CNT films. For this approach, we have synthesized azide-containing CPs to separate semiconducting SWNT and alkyne-based acrylate polymers for substrate immobilization. Based on these polymers, CNT films with high density and stability were successfully grown through a Click reaction. In this presentation, we will also discuss the results of devices based on grown CNT films.
