摘要

本研究在發展一套連續式生產奈米流體之真空潛弧製造系統，主要原理利用壓力差原理配合開關閥之作動，能夠使加工載液能從儲存槽流入加工真空腔體內，同時加工腔體內之奈米懸浮液亦能自動流入保有更低壓之收集腔體中。針對本實驗所生產氧化銅之奈米微粒也進行一些分析，如形貌分析、粒徑分布、結構分析、濃度檢測等。
經由實驗得到時間、崩潰電壓、粒徑、濃度等會影響奈米顆粒粒徑之參數；經過多次比對後發現由實驗結果得知，比電阻值在2550 以上時其平均粒徑為170nm以上，實驗結果發現加工載液之比電阻值的穩定性對於顆粒之粒徑及一致性之影響非常大，
在此設備與原設備所製造出之氧化銅經過比對後，發現此設備所製備出之顆粒粒徑小的分佈比原設備之小粒徑多。

This research aims to develop a continuous Submerged Arc Nanoparticle Synthesis System. using the pressure difference between the valves, the working solution of prepared nanofluids flow into the vacuum chamber. Some analyses including morphology, particle size, structure and concentration detection were preformed to characterize the CuO nanoparticles prepared in this experiment.
The crucial process parameters affecting nanoparticle sizes are the processing time, breakdown voltage and conductivity of the suspension. From the experimental results, it was found that the specific resistance was around 2550 and the average particle size was 170nm. The experimental results indicate that the particle size and disparity are greatly influenced by the stability of the electric conductivity of the prepared nanofluids.
Compared to the CuO nanopaticles prepared differently by the continous and previous fabricating systems, the particle size synthesized by the developed system is much smaller than that prepared by the previous system.
