摘要

本論文，主要為對多壁奈米碳管進行表面改質處理。以超音波震盪與紫外光輻射多壁奈米碳管，可在奈米碳管末端開環及短切。壓克力酸來當作官能基化的媒介，並利用紅外光譜儀來觀察官能基化的反應程度。用不同的奈米碳管添加量填充於環氧樹脂，藉由萬能試驗機、衝擊試驗機與示差掃描熱量計等，來量測環氧樹脂複合材料的機械性質與熱性質。我們發現2%的奈米碳管添加量為最適合，其複合材料的機械性能與玻璃轉換溫度皆可達到最大值。而環氧樹脂的固化反應主要發生於環氧基上，利用紅外光譜儀觀察環氧基的反應情形，進而求出固化反應所需的活化能。在電性方面，奈米碳管以12.87%的添加量，即可完整地形成連續網路結構，發揮其最佳的導電性。

In this study, the surfaces of the multi-walled carbon nanotubes (MWNTs) were treated by acrylic acid. The acid-treated MWNTs were functionalized and characterized by Infrared spectroscopy. The MWNTs were opened at their ends by ultrasonic treating and UV irradiating. Different adding amounts of the opened MWNTs were filled to the epoxy resin, and their mechanical properties and thermal properties were measured by Instron, impact and differential scanning calorimeter (DSC), etc. The optimum adding amount of MWNTs to the epoxy resin is 2.0%, which is according to the parameters obtained from mechanical properties and Tg. The activation energy of the epoxy resin during curing can be calculated from infrared spectra according to the change of the epoxide band. The electrical conductivity of the MWNTs-filled composites was increased with proper (12.87%) amount of MWNTs adding, this is due to the networks constructed between MWNTs completely.
