摘要

奈米碳管目前已被廣泛的應用在各種高科技奈米製程產業之中
。奈米碳管具有良好管狀結構，本身也具有顯著導電性，所以當不同含量的CNTs均勻的分佈在基材中，也可以使基材具有相當程度的導電性。然而由於奈米碳管尺寸甚小，傳統複合材料製程中大多都只是將奈米碳管均勻分布在基材中，甚少討論奈米碳管在基材中分佈的方向性問題。因此本研究將以介電泳法的技術，利用介電泳力，直接操控奈米碳管進行均勻且具有方向性的分佈與排列，透過介電泳法的技術製作出具有方向性排列之高導電度奈米碳管複合材料。

The unusual mechanical and electrical properties of carbon nanotubes(CNTs) make them an ideal class of reinforcement for composite materials. CNTs have high performance in electrical conductivity. So CNTs well dispersed as fillers can successfully reinforce electrical conductivity of composites. In most cases, CNTs were randomly and uniformly dispersed in the composites, the alignment of CNTs in the composites is rarely discussed. So in this study, the application of dielectrophoresis during nanocomposites curing was used to induce the formation of aligned nanotubes between the electrodes. It is possible to make high electrical conductivity composite materials.
