Carbon nanotubes were discovered in 1991. Subsequent studies found that their remarkable material properties (mechanical and electrical) could be an ideal candidate for a wide range of applications. For example, CNTs represent a new class of nanofibers with potential applications on structural reinforcement of polymer as composites or as conduits in nanofluidic systems. Nevertheless, the effect of CNTs on surface/interfacial properties such as those in microfluidic systems is rarely explored. We have recently found that addition of a small amount of carbon nanotubes into a polymer surface could reduce the so-called electroviscous effect from pressure-driven microfluidic systems. In this study, we aim to examine these phenomena in detail by means of the more accurate and analytical research equipment. Successful completion of this project could lead to commercialization of the importance idea in reducing viscous force in microchannels by simply tailoring surface energetics through carbon nanotube addition and hence improves the efficiency for cooling of microelectronics.

碳纳米管于1991年被发现。随后的研究发现，它们卓越的材料特性（机械和电气）可能是广泛应用的理想候选者。例如，碳纳米管代表了一类新的纳米纤维，其在作为复合材料或作为纳米流体系统中的导管的聚合物的结构增强上具有潜在的应用。然而，碳纳米管对表面/界面性质的影响，如那些在微流体系统中很少探索。我们最近发现，在聚合物表面添加少量碳纳米管可以减少压力驱动微流体系统的所谓电粘性效应。在本研究中，我们的目标是通过更准确和分析性的研究设备详细研究这些现象。该项目的成功完成可能会导致商业化的重要思想，在减少微通道中的粘性力，通过简单的剪裁表面能量通过添加碳纳米管，从而提高微电子器件的冷却效率。
