Synthesis of highly concentrated silver nanoparticles assisted polymeric dispersant.

Silver nanoparticles are well known as novel materials as metal electrodes on ceramics, catalyst, antibacterial agent, and etc. The assisted role of polymeric ceramic dispersant on synthesis of highly concentrated silver nanoparticles was studied. The used ceramic dispersants with different kinds of counter ion of polyelectrolyte were polymethylmetacrylic ammonium salt (PMMA, i.e., Darvan C: R.T. Vanderbilt Co.), polyacrylic ammonium salt (PAA), polyacrylic amine salt (PAAm), and polyacrylic sodium salt (PAS). The formation of Ag(0) nanoparticles was followed by UV spectrometer, XRD and TEM. According to TEM investigations Ag(O) nanoparticles with the rage of 10 similar to 20 nm in diameter were produced. The possible concentration of batch - synthesized silver nanoparticles was up to 10 wt%.
