A dispersion comprising metallic, metal oxide or metal precursor nanoparticles, a polymeric dispersant and a sintering additive

摘要

The present invention relates to conductive compositions comprising a specific carboxylic acid as sintering additive. It further relates to a method to prepare such compositions. The compositions of the present invention allow a reduction of the curing time and/or a lowering of the curing temperature when applied to a substrate. Thus, the present invention also relates to a process for curing said conductive compositions and to coated layers or patterns thereof. The present invention is useful to apply conductive compositions on various substrates including thermo-sensitive substrates having a melting point below 200°C and to speed up processes for making conductive layers and/or patterns by substantially reducing the curing times.
