Abstract
Conductive ink for inkjet printing has attracted considerable interest for the preparation of advanced electronic circuits. However, high silver content and multiple printing are necessary in order to acquire better conductivity when using spherical silver nanoparticles. In order to reduce manufacturing cost, triangular silver nanoplates were prepared by modified solvothermal method and used for conductive ink. During sintering process of prtinted patterns, the tips of triangular nanoplates were first melted and turned round for high energy of tips. The resistivity of inkjet printed line is 7.6×10-6 Ω·cm when using triangular nanoplates ink with 10 percent content, while it is necessary to use more than 15 percent content for spherical nanoparticles. This is because surface contact between nanoplates can provide more paths for electron transmission relative to spherical nanoparticles.
