A process of silver nanowire transparent conductive films has been developed to synthesize by organic needle-shaped precursor painting reduction. Needle-shaped nanowire precursors are simply synthesized by ultrasound irradiation of silver oxide and carboxylic acid as starting materials. The aspect ratio of the needle-shaped precursors is chenged by condition of ultrasound irradiation. Silver nanowires can be easily obtained by reducing these needle-shaped precursors with hydrazine gas. The morphology of the resulting nanowires is different from that of typical nanowires that have been reported. The small nanoparticles are connected to form polycrystal nanowire. The polycrystal silver nanowire is considered to increase the transparency of the film because of its rough morphology. This method can synthesize silver nanowires and fabricate the transparent conductive film simultaneously, in low cost and high throughput.
