摘要
采用化学还原法制备纳米银粉,研究了以有机试剂BSG为还原剂,碱性条件下表面活性剂的种类和用量、银离子浓度以及反应温度对所生成银粉粒径的影响。以PVA为表面活性剂,在反应温度为25～50℃、[Ag+]为0.1～0.5mol/L和高速搅拌的条件下,制备出了平均粒径小于100nm的银粉。
Based on the chemical reduction method of organic reductant BSG, the influence of some factors, such as the surfactant and its dosage, the concentration of Ag^＋, the reaction temperature, on the particle size of silver nanopowder under alkaline condition, was investigated. When PVA was used as the surfactant, silver nanopowder with particle size of less than 100nm were prepared under following condition of 25-50℃, Ag^＋ concentration of 0.1 -0.5mol/L and high speed stiring.
