| description | The invention discloses a preparation method of copper nanoparticles with different sizes. According to the method, a non-water-soluble solvent diethylene glycol is used as a reaction medium so as to reduce the oxidation of the nanoparticles as much as possible, and meanwhile, a surfactant polyvinylpyrrolidone (PVP) is added as a dispersing agent so as to disperse the nano material and reduce the oxidation of the nanoparticles. The metal source is copper sulfate pentahydrate, and the reducing agent is sodium hypophosphite. And the copper nanoparticles with different sizes can be prepared in a controlled manner by regulating and controlling the reaction flow rate and temperature. And washing the synthesized copper nanoparticles with absolute ethyl alcohol, and centrifuging. And finally, storing in a-4 DEG C refrigerator.
本发明公开了一种不同尺寸大小铜纳米颗粒的制备方法。该方法中使用非水溶性溶剂一缩二乙二醇作为反应媒介，目的是尽量减少纳米颗粒的氧化，同时加入表面活性剂聚乙烯吡咯烷酮(PVP)用作分散剂，既为了分散纳米材料，又为了降低纳米颗粒的氧化。金属源为五水合硫酸铜，还原剂为次亚磷酸钠。通过调控反应流速与温度，可控制备不同尺寸的铜纳米颗粒。随后对合成的铜纳米颗粒用无水乙醇清洗、离心。最后将其保存在 |
