Influence of Resins on Properties of Copper Screen Printing Conductive Ink
Copper conductive inks for screen printing are being given great attention due to their widely application in printed electronics industry.In this study,copper conductive ink used for screen printing,which were grinded by three-roll mill machine,was prepared using the epoxy,polyurethane and acrylic resins as adhesive,the flake copper particles which had a diameter between 20 to 50 μm as conductive material and butly alcohol was chosen as solvent.The viscosity and the thixotropy of the conductive ink were measured by rheometer.The oxidation of the surface layer of copper were removed by submerged in a certain concentration of acid solution and the resistance of the sample was measured after heated at different various temperatures.The results showed that the rheology of the copper conductive inks added epoxy,polyurethane and acrylic resins for screen printing and the minimum conductivity can be reached 1.93 × 10-3 Ω·cm.
