Original abstract
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.
Czech abstract
Nano suspenze Ag částic byla připravena mokrou syntézou s organickým krytím. Byla monitorována interakce s Cu substrátem. Fenomény, počínaje teplotní aktivací volného povrchu částic až po formování vrstvy Ag na rozhraní mezi dvěma Cu substráty, byly monitorovány různými in-situ technikami, jako termální analýa, mikroskopie a měření vodivosti. Tento monitoring probíhal za různého složení vnějšího plynného prostředí. Důležitým výsledkem je odhad tepelného účinku nízkoteplotního slinování a agregace Ag nanočástic.
