A novel strategy for high-performance transparent conductive films based on double-walled carbon nanotubes†
Abstract
A high concentration of double-walled carbon nanotubes was dispersed by a carbazole-based conjugated polymer. And a transparent conductive film was fabricated via simple dip-coating using this dispersion, which showed simultaneously a low sheet resistance (average 134 Ω □−1, minimal 86 Ω □−1) and an ultrahigh transmittance (99% at 550 nm). This high-performance transparent conductive film has potential applications in future optoelectronic devices demanding ultrahigh transparency and flexibility.
