dc.description.abstract | In this work, the In-Situ properties of silver nanoparticle ink were estimated during laser sintering process. The silver nanoparticle ink was composed of 34 wt% silver nanoparticles with an average size of approximately 50 nm, and was deposited on a glass substrate via inkjet printing technology. A 532 nm continuous-wave laser was irradiated to the printed ink for 60 s under various laser intensities. During the laser irradiation, the In-Situ electrical conductance of the sintered ink was measured to obtain the transient thermal conductivity of the silver nanoparticle ink using the Wiedemann Franz law. The 2-dimensional, transient heat-conduction equation was calculated to obtain the transient temperature of the silver nanoparticle ink. By coupling the calculated temperature with the measured, transient electrical conductance, the transient thermal conductivity of the ink during the laser sintering process was derived in the calculation. The calculated thermal conductivity of the ink sintered at a laser intensity of 467.9 W/cm2 with 598 K is 355.5 W/mK, which is 86.4% of the thermal conductivity of bulk silver, 411.4 W/mK, at that tempearture. The difference resulting from the porosity of the sintered ink has an effect on the thermal conductivity of the sintered ink. | en_US |
