在这篇论文,密度聚乙烯(HDPE )/poly (ethylene-co-butene )(PEB ) 混合的高度(50/50 wt%) 通过答案相配然后压缩塑造被准备,并且随后由扫描共焦的显微镜学(LSCM ) 的激光检验了。在这个实验使用的 PEB 用荧光黄衍生物的小数量被标记显示荧光。起始的电影证明制服在光显微镜学的分辨率以内染分发和阶段分离的没有指示。在到房间温度的快速的冷却跟随的 140 deg C 退火的 Samplefilms 显示出明显的阶段分离和双性人连续结构。现在的工作显示由用荧光黄衍生物标记一个部件, LSCM 能高效地在聚合物混合介绍的 situdepth 表现。
In this paper, high density polyethylene (HDPE)/poly(ethylene-co-butene) (PEB) blend (50/50 wt%) was prepared through solution blending and then compression molding, and subsequently examined by laser scanning confocal microscopy (LSCM). The PEB used in this experiment was labeled with a small quantity of a fluorescein derivative to render fluorescence. The initial films showed uniform dye distribution and no indication of phase separation within the resolution of optical microscopy. Sample films annealing at 140℃ followed by rapid cooling to room temperature showed obvious phase separation and bicontinuous structure. The present work indicates that by labeling one component with fluorescein derivative, LSCM can efficiently perform in situ depth profiling of polymer blends.
