摘要
制备了一种以离子液体BMImBr作为介质主体,阿拉伯胶为分散剂,单臂碳纳米管(SWCNTs)为纳米粒子的纳米流体。考察了分散剂含量、超声时间、超声功率等因素对纳米流体稳定性和分散效果的影响。最佳工艺条件:2 000 0 g BMImBr中加入65.0 mg质量分数为15.38%的阿拉伯树胶水溶液,溶解后加入0.4 mg SWCNTs,在100 W功率下超声分散24 h,然后静置24 h,制备出了一种以离子液体为主体的新型的混合介质的纳米流体。通过电子显微镜对流体的形貌进行了表征,结果表明,SWCNTs均匀的分散于介质中。
The nanofluid,using BMImBr as the main body medium,gum arabic as the dispersing agent,SWCNTs as nanoparticle,was prepared.The effect of dispersing agent content,supersonic time,supersonic power on nanofluid＇s stability and dispersion were investigated to get the optimum condition.The nanofluid was prepared in the following way：dissolved 65.0 mg 15.38% gum Arabic water solution into 2.000 0 g BMImBr and added 0.4 mg SWCNTs,and then dispersed it 24 h at a ultrasonic treatment power of 100 W and let it sit for 24 h.Its morphology was observed by the electron microscope.The result showed that SWCNTs were well dispersed in the medium.
