Uniform percolation of inkjet-printed polymer-semiconductor-wrapped carbon nanotube networks by blending with insulating polymer

•The inkjet-printed thin-film transistors (TFTs) were fabricated with the polymer-semiconductor-wrapped single-walled carbon nanotube (PSC/SWCNT) networks.•By introducing the insulating polymers into the PSC/SWCNT network, the improved uniformity of the performance of inkjet-printed PSC/SWCNT network TFT was achieved.•The PSC/SWCNT networks blended with the polymer binder resulted in high-performance PSC/SWCNT network based TFTs with a relatively uniform field-effect mobility of 7.57±3.32cm2/V·s.
