Abstract
With the rapid development of printing electronics, conductive ink as an important part of printing electronics, the electrical conductivity of which printed on different substrates has become the focus of research. In this paper, the printed circuit of different patterns and thickness of ink layer were printed on photo paper and PET film by using the nano-silver conductive ink with the particle size of 30 nm and solid content of 5–10%, and its conductivity was tested under different sintering temperature. The experimental results showed that the circuit could still maintain good electrical conductivity with the change of printing pattern. As the thickness of the ink layer increases, the circuit width becomes wider, the conductivity of the circuit gradually increased and it decreased after reaching a certain number of layers. The conductivity increased rapidly with the increase of sintering temperature and it tended to be stable after slowing down when reaching a certain temperature. As the sintering time going by, the electrical conductivity of the circuit increased swiftly first and the growth trend became slower.
