The flexible and printed electronics using polymer substrates have attracted substantial interest as advanced alternatives to conventional photolithography. As the first step to produce these electronic devices, it is necessary to fabricate conductive films, lines, circuits and tracks. Therefore, synthesis, printing and sintering techniques of nanoparticle pastes have been recently investigated. In this work, the effect of poly (N-vinylpyrrolidone) (PVP) molecular weight (MW) on the flash light sintering of copper nanoparticle paste was studied. The copper nanoparticle paste was coated on polyimide substrates using doctor blade method. PVP was used as reducing agent to functionalize the copper nanoparticles during flash light sintering process. To find the optimum sintering conditions of copper nanoparticles, the various MWs of PVP (10,000, 40,000 and 55,000) were used and the flash light irradiation energy was varied from 7.5 J/cm2 to 17.5 J/cm2. Meanwhile, other flash light irradiation conditions (pulse numbers, on-time and off-time durations) and amounts of PVP were fixed to clarify the effect of the PVP MW. As the results, it was found that flash light sintered copper nanofilms have the resistivity 54 μΩcm without any damages to the polymer substrate.
