本研究使用熱裂解化學氣相沉積法 ( Thermal Chemical Vapor Deposition )以非金屬催化的方式在碳煙(N550)上生成奈米碳管，藉此提升了碳煙之電性，預期能夠作為優良的導電碳材。將碳煙N550基材藉由氧化及酸化改質表面以增加活性位置並經由熱處理過程清除汙染物和提高基材穩定性，接著在不同溫度下通入定比例碳源混合氣體經由高溫裂解碳源沉積於基材上之活性位置，同時生長出奈米碳管。利用掃描電子顯微鏡、穿透式電子顯微鏡以及拉曼光譜儀觀測其形貌、結構、長度、管徑，以及石墨化程度；由熱重分析儀量測熱處理過程對基材穩定性的影響以及氧化速率；再以循環伏安法 (Cyclic Voltammetry ) 測定含碳管基材的導電性質，求得異相電子傳遞速率常數 (K0)。藉由此方法來說明修飾導電碳煙的電子傳遞速率，並且比較在不同生長變因下其結構特性對導電性的影響。N550碳煙經過奈米態管生長處理後，其導電性能提升至原本的5倍。
