Nano-zirconia fiber physical property by change the calcine temperature and ratio of precursor

Abstract

ZrOCl2/PAN composite nanofibers were prepared by electrospinning, through 700、800、900、1000℃ calcinations ZrO2 ceramic nanofibers was fabricated. X-ray diffractometry (XRD) proved that ZrO2 ceramic nanofibers generated. The microstructure of ZrOCl2/PAN composite nanofibers were characterized using scanning electron microscopy (SEM). The study has showed that: The morphology and formation of ZrOCl2/PAN composite nanofibers, ZrO2 ceramic nanofibers of the monoclinic phase was mixed with tetragonal phase was fabricated. To compare commerce ZrO2 the 30％ZrOCl2/PAN ceramic nanofibers have heat radiation.

摘要

本實驗利用靜電紡絲法製備ZrOCl2/PAN複合奈米纖維，選用電壓16 kV、距離10 cm、流量：0.5 mL/hr、電紡時間15 hr、滾筒速度40 rpm ，再進行700、800、900、1000℃燒結處理，以得到不同結構之ZrO2奈米陶瓷纖維材料。運用掃描式電子顯微鏡(SEM)進行纖維外觀分析，以及研究ZrOCl2/PAN複合奈米纖維的熱性能和燒結處理過程，並由X-射線粉末繞射(XRD)驗證了ZrO2奈米陶瓷纖維的生成。由實驗結果得知，所製備的ZrOCl2/PAN複合奈米纖維外觀良好，燒結處理後得到單斜晶型和四方晶型混合體系的ZrO2奈米纖維，且和商業用ZrO2比較，30% ZrOCl2/PAN奈米陶瓷纖維更具有散熱能力。
