Conducting electrodes and films are becoming increasingly important for the printed electronics which can be applied in various fields such as RFID tags, photovoltaics, display and PCB. And copper nanoparticle inks serve as an attractive potential replacement to silver nanoparticle inks because its low cost and good electrical conductivtiy.In this paper, the commercial copper nanoparticle powder with oxide shells were dispersed in the solvent of ethylene glycol. Poly (N-vinylpyrrolidone) (PVP K30) was added to the solvent as capping materials. The prepared copper ink was spin-coated on glass substrate under ambient conduction. Then, the deposited Cu ink was sintered by an intense pulsed light (IPL) system. The sintering effects were investigated with different sintering conditions including pulse energy and pulse duration. The resulting electrical resistivity was 94.1uΩ·cm which is about fifty times as high as that of bulk copper. The high resistivity may be mainly attributed to the porosity of sintered film. Also, crystal phase analysis was performed using x-ray diffraction (XRD) and was found the XRD peaks corresponding to cuprous oxide disappeared after IPL sintering. It was believed that PVP reduced the copper oxide to copper in the process of IPL sintering.

ABSTRACTInkjet printing of various nanoparticle inks, made from silver or copper nanoparticles, and its transformation into solid functional patterns is of high interest in the field of printed electronics. Liquid materials can be deposited as defined patterns in selected areas with micrometer precision. To convert these printed liquid films, consisting of solvents, additives and nanoparticles, into solid functional patterns a post-treatment is required. To this date, many investigations report on various sintering techniques to achieve e.g. high conductivity from the printed conductive materials.Direct thermal sintering (via furnace or hotplate) requires high temperatures, which makes it not suitable for sensitive polymeric substrates. The novel method of intense pulsed light (IPL) sintering opens the window of opportunity to convert liquid or dried metal layers into solid functional layers within milliseconds without damaging the thermally fragile polymeric substrate.In this work we present and analyze the application of the IPL sintering on inkjet printed silver patterns on various flexible substrates, like Poly(ethylene naphthalate) (PEN), Poly(ethylene terephthalate) (PET), Polyimide (PI) foils and paper.A high dependency of the electrical and structural performance of the printed silver layers on the base substrate was observed when flashing with the IPL technique. Flashing parameters were varied and the resulting sheet resistance is presented.With the analytical comparison of optical and electrical results, the flashing settings could be adapted to achieve highly conductive inkjet printed silver patterns on flexible substrates, when compared to other thermal sintering techniques. Furthermore the first integration of this post treatment methodology into semi-industrial roll-2-roll processing was successfully performed and will be demonstrated.
