In this paper, carboxylated carbon nanotubes (MWCNTs-COOH)/thermoplastic polyurethane (TPU) composite films with conical microstructure on the surface were directly prepared without an external template by optimizing the parameters of the electrostatic spinning process (RPS). The conductive network and its mechanical properties were enhanced by hydrogen bonding between MXene and TPU. This improved the sensitivity and increased the detection range simultaneously.
