研究了铜/银合金纳米粒子的制备方法,用抗坏血酸做还原剂,制备了粒径小的纳米铜粉。由于纳米铜粉的稳定性差,易氧化,为了提高其稳定性,在制备的纳米铜粉中加了少量的Ag+,在纳米铜粉表面还原制备出银纳米层覆盖于在铜上。所制备的纳米铜/银合金纳米粒子稳定性好,具有纳米粒子的效应,有望应用于印制电路的制造。该制备方法可以减少传统印制电路板制作方法的工序,节约资源,且减少对环境的污染。
研究瞭銅/銀閤金納米粒子的製備方法,用抗壞血痠做還原劑,製備瞭粒徑小的納米銅粉。由于納米銅粉的穩定性差,易氧化,為瞭提高其穩定性,在製備的納米銅粉中加瞭少量的Ag+,在納米銅粉錶麵還原製備齣銀納米層覆蓋于在銅上。所製備的納米銅/銀閤金納米粒子穩定性好,具有納米粒子的效應,有望應用于印製電路的製造。該製備方法可以減少傳統印製電路闆製作方法的工序,節約資源,且減少對環境的汙染。

The preparation method of copper/silver alloy nanoparticles was studied. The small particle size of nano copper was prepared by using the environmentally friendly ascorbic acid as a reducing agent. But this nano copper had poor stability, and is easy to be oxidized. In order to improve its stability, a small amount of Ag+was added during the preparation of nano copper. The silver layer was covered on the nano copper surface by reduction reaction. The copper/silver alloy nanocrystalline possesses good stability and nanoparticles effect. The copper/silver alloy nanoparticles are expected to having potential application in production of printed circuits. The preparation method has shorter product process than the conventional PCB production, thus it can save resources and reduce the environmental pollution.
