The effect of surface treatment on the line formation of inkjet-printed silver nanoparticles

Abstract

As line was formed using inkjet printing, how the line width was determined and a degree of bulge occurrence were investigated with changing surface energy of substrate through UV/O 3 treatment and a degree of overlap of single droplets. Also, line width experimentally measured was compared with geometrically calculated line width. The number of bulge per unit length was investigated with a degree of overlap. The diameter of deposited single droplet increased as contact angle decreased, and contact angle of deposited single droplet was close to advancing angle. Line width increased as contact angle decreases and a degree of overlap of single droplet increases, and line width was determined by abvancing contact angle. Also, the number of bulge per unit length was minimum as a degree of overlap was 50-60 %.
