Sintering of silver nanoink deposited on flexible substrate by conventional thermal method
Due to their unique optical, electrical and thermal properties, silver nanoparticles (AgNP) have become the prominent material for application in various research fields, such as catalysis, biotechnology, optics end electronics.[1, 2] In the case of flexible electronics, inkjet printing of nanosilver ink represents an attractive technology for precise deposition of conductive substance on different polymeric substrates. Electrical conductivity, a key factor in measuring performance of printed electronics, greatly depends on post- fabrication sintering process.[3] Thus, formulation of a stable AgNP colloidal suspension, which allows easy removal of the grain-stabilizing agent in slightly elevated temperatures to produce electrically conductive material is required. In this work, two novel conductive inks were synthesized – both based on silver nanoparticles, but stabilized with two distinctive capping agents – Poly(acrylic acid) (PAA) and Poly(methacrylic acid) (PMA), respectively. Nanoinks were inkjet printed on flexible PET substrates and thermally treated in order to produce conductive bulk silver patterns. Combination of parameters such as width, length and thickness of the printed lines, temperature conditions ranging from room to elevated values, and sintering time were studied. It has been shown that the silver lines with best conductivity measurements were generated at temperatures above 100°C, regardless the type of capping molecule. Also, minimum of 200 μm line width was needed to obtain conductivity of printed electrode.
