Abstract:
Metal conductive ink for flexible electroncs has exhibited a promising future recently. Here, an innovative strategy was reported to synthesize silver nanocolloid (2.5 ± 0.5 nm) and separate solid silver nanoparticles (<10 nm) effectively. Specifically, silver nitrate (AgNO3) was used as silver precursor, sodium borohydride (NaBH4) as reducing agent, fatty acid (CnH2n+1COOH) as dispersant agent, ammonia (NH3•H2O) and hydrochloride (HCl) as pH regulator and complexing agent in aqueous. The main mechanism is the solubility changes of fatty acid salts (CnH2n+1 COO-NH4+) and fatty acid (CnH2n+1 COOH) coated on the synthesized silver nanoparticles (NPs) in aqueous. This change determinates the suspension and precipitation of silver NPs directly. The results show that when n in dispersant is 12, and molar ratio (C12H24O2/AgNO3) is 1.0, the separation yield of silver NPs is up to 94.8 %. After sintered at 125 ℃ for 20 minutes, the as-prepared conductive silver nanoink (20 wt. %) presents a satisfactory resistivity (as low as 6.6 μΩ.cm on polyester-PET substrate), about 4 times the bulk silver. In addition, the efficacy of the as-prepared conductive ink was verified with the construction of radio frequency antenna by inkjet printing and conductive character pattern (Fudan-Fudan) by direct wiring, showing with excellent electrical performance.
