Abstract
The present invention relates to a dispersion comprising metallic, metal oxide or metal precursor nanoparticles and a polymeric dispersant, the dispersant comprising an anchor group with affinity for the metallic, metal oxide or metal precursor nanoparticles that is chemically bonded to a polymeric backbone characterized in that the dispersant has a 95 wt. % decomposition at a temperature below 300° C. as measured by Thermal Gravimetric Analysis. It further relates to metallic fluids or inks prepared from the dispersion and to the preparation of the dispersion and the metallic fluid or inks.
