摘要

奈米碳管是一種新型的碳材料。從奈米碳管被發現到現今為止，它的各項特性都一直令人好奇與驚喜，如機械強度、韌性、導熱性、電傳導方向都有優異表現，均遠超過於一般鋼鐵材料，因此受到許多學者廣泛研究與討論。近年來已有許多利用奈米碳管於高分子聚合物的複合材料研究，其目的在於提升高分子複合材料的性能。本論文主要針對多壁奈米碳管添加於聚氨酯發泡為複合材料作隔振相關性能研究；首先利用田口品質工程法(Taguchi Method)對多壁奈米碳管/聚氨酯發泡複合材料進行穩健最佳化製程設計，藉由力阻隔實驗以獲得最佳化製程參數。接著使用最佳化製程之新隔振複合材料對結構阻尼、吸收能量進行分析研究，並利用窄頻譜與倍頻譜進行隔振墊片的隔振性能分析。同時使用掃描式電子顯微鏡(Scanning Electron Microscope, SEM)觀察多壁奈米碳管在聚氨酯發泡材料分佈情況。

The carbon nanotube is a new kind of carbon materials. Since it has been found, there are several marvel properties related to this material, such as good conductivity of heat and electricity, superb mechanical strength and toughness higher than steel, which are popularly reported by engineers. Recently, a lot of researches about CNT/polymer composite have been made in order to enhance the performance of such material. This work is focused on the research of using the MWCNT/PU foam composite as the vibration isolator material. First, the Taguchi Method is used to obtain the robust design and the optimal parameters of fabrication for the MWCNT/PU foam composite. Under the optimized settings, the analyses of the structure damping and energy absorption of the new proposed polymer composite material have been done, too. The narrow bandwidth and octave bandwidth spectrum are equipped to analyze the abilities of the vibration absorption of the anti-vibration sample pad. Finally, we use the scanning electron microscope (SEM) to observe the dispersion condition of MWCNT/PU Foam composite.
