高能量高密度脉冲等离子体轰击HDPE薄膜表面微观结构的研究

Surface microstructures of HDPE films bombarded by pulsed high energy density plasma

本文利用ＳＥＭ 研究了高能量高密度脉冲Ａ１ 等离子体轰击高密度聚乙烯（ＨＤＰＥ）薄膜引起的表面微观结构变化。结果表明：等离子体单脉冲轰击导致ＨＤＰＥ 薄膜表面局域熔化和非晶化；随着脉冲次数的增加，ＨＤＰＥ 薄膜表面微观结构发生明显变化。化学分析和红外光谱分析表明ＨＤＰＥ

Surface microstructures of HDPE films bombarded by pulsed high energy density plasma were observed using scanning electron microscopy (SEM).Domain melting and amorphous of HDPE surface were induced by Al atoms bombardement with single pulse plasma.With the increase of the pulse times of plasma,the surface microstructures of HDPE films dramatically changed.The crosslinking reaction of HDPE films was investigated by chemical analysis and FTIR measurements.The surface microstructures of HDPE films were controlled by thermal\|spike effects and crosslinking reaction. 
