Originální abstrakt
Silver nanoparticles (Ag-NPs) were prepared by wet synthesis. The Ag-NPs suspension and the copper substrate plate were used for a preparation of substrate-nanoparticle-substrate samples. The sandwich like samples Cu/Ag/Cu were prepared and investigated in-situ at the isothermal external conditions (IEC) and inside apparatus for simultaneous thermal analysis STA409. The in-situ results of the electrical resistance were recorded during the Cu/Ag/Cu (IEC) sample preparation and heat treatment. Thermal effects of the Ag-NPs sintering between copper substrates were measured by differential scanning calorimetry (DSC) under different atmospheres. The prepared Cu/Ag/Cu sandwich samples were characterised by means of both optical and electron microscopy. The process of the low temperature sintering of the Ag-NPs was monitored using both thermogravimetry (TG) and DSC technique inside calorimeter under inert gas and under synthetic air. The exothermic heat effect of nanosilver sintering was evaluated.

Nanočástice Ag byly připraveny mokrou syntézou. Suspenze nanoAg byla nanesena mezi měďěné plíšky a nízkoteplotní syntrací nanočástic vznikl model pájeného spoje.
