超临界水降解聚乙烯废弃物的研究

Study on Degradation of Polyethylene Waste in Supercritical Water

以超临界水为反应媒介,镁粉为催化剂,在600℃将商用聚乙烯薄膜转化为管径50nm左右的多壁碳纳米管。利用粉末X射线衍射、透射电子显微镜和拉曼光谱等手段对碳纳米管进行了表征。

Polyethylene （PE） film is transformed into carbon nanotubes which diameter of 50 nm,the reaction use supercritical water as reaction media, magnesium powder as catalyst, temperature is 600℃. The products are characterized by X - ray diffraction, transmission electron microscopy and Raman spectroscopy et al.
