摘要
氩电弧等离子体法制备碳包铜纳米粒子,采用双氧水化学处理和添加十二烷基苯磺酸钠两种方法制备碳包铜-水纳米流体,探讨了不同分散方法对碳包铜纳米流体导热性能的影响。结果表明,双氧水化学处理碳包铜纳米粒子制备水介质分散体系具有比添加分散剂制备分散体系更高的导热性能。采用化学处理法,添加质量分数为2.0%的碳包铜-水纳米流体导热率可提高60%。
Carbon-encapsulated copper nanoparticles were synthesized by carbon arc discharge technology,carbon-encapsulated copper-water nanofluid was prepared by two different method,chemical treatment with H2O2 and adding SDBS dispersant respectively.The effect of dispersion method on thermal transport of nanofluid was studied.The test indicated that the nanofluid prepared by chemical treatment to carbon-encapsulated copper nano-particle had higher thermal conductivity than that prepared by adding SDBS dispersant.There was a 60% enhancement in thermal conductivity with 2.0%（mass fraction） carbon-encapsulated copper loading using chemical treatment preparation method.
