用共聚焦显微镜对高密度聚乙烯(HDPE)和茂金属催化合成的短支链聚乙烯(PEB)(50/50)共混物的形态进行了三维研究.PEB标记了少量的荧光染色剂,未热处理的HDPE/PEB共混物样品呈现均相形态.HDPE/PEB共混物在140℃热处理1320min后,由共聚焦显微镜(LSCM)观察显现出双连续的相态结构.
The morphology of blends of HDPE and metallocene-catalyzed short-chain branched polyethylene (PEB) (50/50) was investigated by confocal microscopy. A small amount of fluorescent dye was labeled with PEB, The HDPE / PEB blends samples without heat treatment showed a homogeneous morphology.HDPE / PEB blends showed a bicontinuous phase structure by confocal microscopy (LSCM) after heat treatment at 140 ℃ for 1320 min.
