Inkjet Printable Dispersions of Silver and Gold Nanoparticles Open Access

Miniaturization and increased complexity of electronic devices are two major trends in the electronic industry. Recent research indicates that inkjet printing can be successfully used in building smaller and more complex structures. This paper describes new methods for generating inkjet printable dispersions of highly dispersed silver and gold nanoparticles. The patterns deposited with a ‘drop-on-demand’ inkjet printer were sintered at different temperatures and converted into thin, highly conductive metal layers. In the case of silver, we show that the film microstructure and electrical resistivity can be tailored by using bimodal particle size distributions.
