摘要: 用混合晶红外光谱法和SAXS、DSC和LAM等方法研究了聚乙烯单晶在75℃、90℃和105℃退火前后的结构变化,发现在90℃以下和105℃以上退火,遵循不同的退火机制

Abstract: Structure changes in polyethylene single crystals caused by annealing at 75, 90 and 105℃ were examined by the mixed crystal infrared spectroscopy, SAXS, DSC and Raman spectroscopy. It was found that different annealing mechanisms were obeyed below 90℃ and above 105℃.

Key words: polyethylene, deuterated polyethylene, infrared spectroscopy, single crystals, annealing
