摘要

本文提出了一种在EG/水中制备碳纳米管防冻纳米流体的更好的替代方法,改进了需要长时间超声的传统方法。对样品进行长时间的超声检测不仅耗时耗力,而且可能使碳纳米管的结构变形。在改进的方法中,纳米流体的制备是通过超声将碳纳米管分散到EG中,然后加水再超声。研究表明,与传统方法所需的5 h超声时间相比,该方法可在1.5 h的超声时间内制备纳米流体。FTIR光谱显示,EG与碳纳米管的相互作用是通过反式构象发生的,与传统方法制备的纳米流体(50天)相比,这种方法制备的纳米流体(85天)具有更高的稳定性和更好的相互作用。与传统方法制备的纳米流体相比,该方法制备的纳米流体具有更好的物理化学性能。该方法制备的纳米流体在较短的超声时间内具有较高的稳定性和较好的物理化学性能。因此,它是制备碳纳米管(EG/水)纳米流体的一种更有效、更经济的技术。

Evaluation of Stabilization and Physical–Chemical Properties of CNT Antifreeze Nanofluid Prepared in 50:50 EG/Water by Modified Strategy
This article proposes a better alternative method to prepare CNT antifreeze nanofluid in EG/water by modifying the conventional method that requires long hours of sonication. Sonicating a sample for long hours is time and energy consuming and may deform the structure of CNT. In the modified method, the nanofluid preparation was carried out by dispersion of CNT in EG via sonication followed by adding water and again sonication. The study shows that nanofluid could be prepared in less sonication time of 1.5 h compared to the 5 h required in the conventional method. FTIR spectroscopy revealed that interaction of EG with CNT occurs via trans conformation resulting in greater stabilization and better interaction of nanofluid prepared by this method (85 days) as compared to nanofluid prepared by the conventional method (50 days). The nanofluid prepared by this method has better physical–chemical properties compared to nanofluid prepared by the conventional method. The nanofluid prepared by this method showed higher stability and better physical–chemical properties at a lower sonication time. Hence it is a more effective and cost efficient technique for preparing CNT (EG/water) nanofluid.
