This work reports the preparation and application of microwave thermally expanded graphene (G)/polyaniline (PANI) conductive paste. The results from XRD revealed that the polyaniline did not change its crystal structure after being combined with microwave thermally expanded graphene. FTIR and Raman spectra revealed that there was a strong pi-pi interaction between polyaniline and microwave thermally expanded graphene. The resultant conductive pastes possess obvious shear-thinning phenomenon, which are suitable for screen printing to produce conductive circuits. The printed polyester fabric showed significant conductivity which can be tuned by changing the printing time and line length. This study paves the way to large-scale fabrication of flexible conductive circuits for various applications.
