Research on conductive performance of inkjet printing samples by conductive inkjet ink
By using the liquid-phase chemical reduction method, under the protection of PVP at the use of hydrazine hydrate reduction of silver nitrate, obtain a nano-silver suspension of high concentration. After adjusting parameters such as surface tension, conductive ink-jet ink was prepared for printing on. With digital microscopes, scanning electron microscopy (SEM) and four-probe tester, different samples of printing times were characterized. Results show that samples which printed for more than two times have conductive capability. Printing samples will be treated by washing treatment, low temperature heating treatment and laser sintering treatment. It was found that its conductive performance can be improved. One of the post-treatments by the laser sintering could obtain a best proof which’s surface resistance reduced to 4Ω/□ after sintering which was 270 Ω/□ previously.
