CONDUCTIVE INKS OBTAINED BY COMBINING AQCS AND METAL NANOPARTICLES

摘要

The invention relates to conductive inks obtained by combining AQCs and metal nanoparticles. Atomic quantum clusters (AQCs), which melt at temperatures of less than 150 ºC, are used as low-temperature "flux" for the formulation of conductive inks. The combination of AQCs with bimodal and trimodal mixtures of nanoparticles of various sizes guarantees the elimination of free volumes during final sintering of the nanoparticles in order to achieve electronic structures with very low resistivity (close to that of the massive material) with low-temperature thermal treatments (< 150 ºC).
