| Description | Silver bimodal nano-suspension was prepared by a wet synthetic route. Organic cover protected the particles. Interaction with copper substrate was monitored. The phenomena starting with temperature activation of the free surface of metallic nanoparticles and finishing with the formation of a bulk layer of Ag in between two Cu substrate were monitored by different in situ methods of thermal analyse, microscopy and conductivity measurement. This monitoring was carried out under different outer gas conditions. An important outcome is the estimation of heat effect, which is produced during low-temperature sintering and aggregation of the Ag nanoparticles. |
