PS/HDPE共混薄膜体系的相态结构分析
|
摘要
利用共焦显微拉曼深度扫描仪和拉曼Mapping成像技术研究了不同比例PS/HDPE及其以SEBS作为增容剂共混体系的相态结构。当体系未加增容剂时,PS和HDPE发生严重的相分离,相态结构分布不均,相界面清晰。加入增容剂之后,共混体系中分散相以不规整的形状被包裹在连续相里面,两相界面变得较为模糊。这是因为增溶剂能与PS和HDPE都能发生相互作用,从而导致不相容的两相分子在相界面出的渗透能力和分子的扩散能力增强。因此,共混体系的相界面变大,体系的相容性增强。
Morphology in polystyrene( PS)/high-density poly( ethylene)( PS/HDPE) with SEBS had been analyzed by the depth scanning of confocal and Raman microscopy and Raman Mapping. The incompatible film showed heterogeneous distribution with phase separation behavior. However,the viscosity status and dispersibility between PS and HDPE could be substantially improved by introducing SEBS to the blend system. The compatibilizer connected with PS and HDPE chians,resulting in the permeability and diffusion of two phases molecular enhancement in the interface. Therefore,the phase interface and compatibility of blending system could be enhanced by introducing the compatibilizer.
