Effect of Conductivity of the Aqueous Solution on the Size of Printable Nanoparticle

摘要: Direct writing technology using nano/microsize particles in aqueous solution is currently one of the leading candidates to bring a substantial advancement technical arena. However, little known about an effect conductivity including metal ions on nanoparticle size for direct technology. It believed that can influence reducing environmental solutions. In this study parameters which affect electric were characterized by changing concentration copper ion, surfactants, and anion compounds. The mobility ion media with respect was most pronounced factor control created nanometals water. due high reactivity large surface area, nanocopper oxidized varied range 7 360 mS/cm when Cu(NO3)2⋅3H2O dissolved water from 0.03–3.0 mol/dm3. condition, nano vary 10 500 nm. Various concentrations surfactants two Cu compounds used verify particle size. Decreasing had corresponding decreased 67 56 adding surfactant 0.1 0.5 mol/dm3 consequently, sizes 89 21 Copper nitrate chloride electrical sizes. This not dependent kind chosen change conductivity. used, nm, while it 91 nm CuCl2⋅2H2O used.
