The main object of this research is to investigate synthesis of Cu23Cl Cu and CuO nanoparticles through electrospinning and heat-treated method The research is mainly focused on preparative parameter and the change of heat-treated temperature to form the nanoparticles inlaid in silicon fibers the shape and color change are dicussed First of all to prepare the Polyvinyl butyral and silica dioxide complex nanofiber by electrospinning and then to investigate different heat-treated temperature and reactive time to being an influence on the products The results detected by SEM XRD TEM EDS FTIR combined sol-gel process and electrospinning can prepare Polyvinyl butyral and silica complex nanofiber The experimental result is found when heat-treated temperature is 100~4750C it can produce Cu23Cl nanoparticles; Above 4750C~ 4900C it can produce Cu nanoparticles; Above 450~7000C it can produce CuO nanoparticles And the viscosity is lain between 20~40cp and the sol-gel process time is 3hr it can produce the thinner fibers The average diameter of the fibers are 107 88±21 01nm;Due to the nanoparticles inlaid in the silica fibers the thinner fibers can be inlaid the smaller nanoparticles so this is the result that the experiment is expected To calcine the complex fibers is to produce surface silica fibers contain Cu23Cl Cu and CuO nanoparticles due to surface plasma resonance it make the color of the fibers become yellowish green from light white green turn into the red nuclear finally As the experimental result to utilize sol-gel process combine electrospinning can produce porous silica fibers contain Cu23Cl Cu and CuO nanoparticles

本研究旨在探讨「利用放电纺丝和热处理法来合成Cu23Cl、Cu和CuO奈米粒」之研究，实验著重在制备参数与热处理温度变化对所形成的奈米粒镶嵌在二氧化矽纤维中的形态与颜色变化探讨。首先，利用放电纺丝法制备出聚乙烯醇缩丁醛及二氧化矽之奈米纤维，比较不同的热处理温度与反应时间的改变对产物生成产生影响，进而研究不同热处理温度和时间对生成奈米粒的影响。产物经由SEM、XRD、TEM、EDS和FTIR等仪器分析结果显示，结合溶胶-凝胶法(sol-gel process)和放电纺丝法可产生聚乙烯醇缩丁醛及二氧化矽复合奈米纤维。实验结果发现，若热处理温度在100~4750C下可得到Cu23Cl奈米粒，475~4900C 可得Cu奈米粒，450~7000C以上可得 CuO奈米粒。而黏度介於20~40cp间和溶胶-凝胶时间为3hr时，可产生直径比较细的纤维，纤维直径为107 88±21 01nm；且由於奈米金属颗粒镶嵌在二氧化矽纤维中，直径比较细的纤维，可以得到比较小的奈米金属颗粒，这与实验预期相符。而锻烧此复合物产生多孔的二氧化矽纤维并包含Cu23Cl、Cu和CuO奈米微粒时，由於表面电浆子共震关系，而使纤维颜色由淡白黄绿色变成黄绿色，再变红褐色。由实验结果得知，利用溶胶-凝胶法(sol-gel process)结合放电纺丝法和不同热处理温度，可产生Cu23Cl、Cu和CuO奈米粒镶嵌在二氧化矽纤维。
