Abstract:
All-printed electronics has attracted attention due to their fast processing and low cost. Inkjet printing allows circuit components to be directly drawn at a specific area in one step. The printed patterns can be used to fabricate micro-conductors, resistors and capacitors. The formability of printed tracks is thus very important. This study investigates the inkjet printing of conductive tracks by silver nitrate solution with poly(N-vinyl-2-pyrrolidone) (PVP) additives. Increasing the PVP content improves the formability of printed conductive tracks. However, excessive additive induces a sheet shape precipitation and decreases the conductivity. The optimal line width is 25 μm and the resistivity is about 7.28 μΩ∙cm
