Abstract
A dispersion includes metallic, metal oxide, or metal precursor nanoparticles; a thermally cleavable polymeric dispersant; an optional dispersion medium; and a thermally cleavable agent. Pastes, coated layers, and patterns may contain the dispersion. A method for producing the specific thermally cleavable dispersant and for producing the metallic nanoparticle dispersions. The dispersions allow the reduction or avoidance of organic residue in coated layers and patterns on substrates, the use substrates of low thermal resistance, and faster processing times.
