Electrical and thermal conductive polymers have aroused extensive interest in research recently due to their hi‐tech applications in the fields of novel electronics. A novel electrical and thermal conductive nanocomposite (MWCNTs@PU/TPU) made with multiwall carbon nanotubes (MWNTs) and thermoplastic polyurethanes (TPU) by using azide polyurethane (PU) as interfacial compatibilizer. The MWNTs could form well‐developed electrical and thermal conductive networks in the TPU matrix. The developed nanocomposite inherited advantageous properties from its constituents, namely the high conductivity and diathermancy from MWNTs, and the high mechanical properties from the TPU. Conductivity tests showed that, compared with neat MWCNTs/TPU, the electrical conductivity of MWCNTs@PU/TPU was significantly enhanced (up to 3.4 × 10 −6 S/cm), with incorporating only 3.0 wt% MWCNTs@PU. And most importantly, the thermal conductivity was greatly improved by about 46.4% when the MWCNTs@PU loading was 6.0 wt%.
