- We report an efficient inkjet printing of water-based pristine GNPs graphene ink and a facile aqueous halogen doping process that provides significant and thermally stable conductivity enhancement of printed patterns. Highly concentrated aqueous graphene ink populated by few-layer pristine graphene flakes is obtained by means of scalable shear exfoliation process with the aid of bromine intercalation. The as-printed GNP films which has been merely treated by drying at 100 degrees C exhibits DC conductivity (sigma(DC)) of similar to 1400 S/m likely due to bromine doping effect. This value is significantly increased to similar to 3 x 10(4) S/m when an additional treatment by means of dipping in aqueous iodine solution is applied prior to the drying. As contrast, sigma(DC) is increased to similar to 2.4 x 10(4) S/m when a mere annealing at elevated temperature in air is employed. When the aqueous iodine doping process and annealing at elevated temperature is combined, an unprecedented value of sigma(DC) similar to 10(5) S/m is achieved. The availability of water-based GNPs inks and low-temperature doping scheme for efficient and reliable conductivity enhancement has offered a pathway for the application of GNPs in different printed electronics devices.
