Abstract

The use of a weakly binding ligand to facilitate sintering between particles and a planar substrate in the absence of pressure and at low homologous temperature has been explored. Ag nanoparticles in the 5-15 nm range suspended in water and stabilized by a BH₄ complex were dropped onto a polished Ag substrate heated to 333 K. The Ag particles sintered to each other and to the substrate to form a largely pore free system. A molecular dynamics simulation is used to understand the theoretical limits of pressure free sintering and practical implications for adhesive systems based on Ag nanoparticle suspensions are discussed.
