Abstract

Utilizing a two-step method, in this study prepared MWCNT-based nanofluids with and without Sodium dodecyl sulfate (SDS) surfactant at concentrations of 0.01, 0.03, and 0.05%. The incorporation of SDS significantly reduced sedimentation, enhanced stability as shown by UV-visible spectroscopy. After 720 hours, sedimentation rates in 0.03% nanofluids were similar regardless of surfactant use, while at 0.01 and 0.02% concentrations, those with surfactants sedimented more slowly than those without. These findings suggest that surfactant addition could be a valuable strategy for optimizing the performance of nanofluid-based applications.

研究表面活性剂对基于 MWCNT 的纳米流体中沉降过程的影响

摘要本研究采用两步法制备了含有和不含十二烷基硫酸钠（SDS）表面活性剂的基于 MWCNT 的纳米流体，表面活性剂的浓度分别为 0.01%、0.03% 和 0.05%。加入 SDS 后，沉降明显减少，紫外可见光谱显示稳定性增强。720 小时后，无论是否使用表面活性剂，0.03% 纳米流体的沉降速度都相差无几，而在 0.01% 和 0.02% 的浓度下，添加了表面活性剂的纳米流体的沉降速度要比未添加表面活性剂的纳米流体慢。这些研究结果表明，添加表面活性剂是优化纳米流体应用性能的重要策略。
