三异丙氧基混合稀土掺杂改性聚苯乙烯的研究

Study on Modified Polystyrene Adulterated with Mixed Rare Earth Triisopropoxide

用廉价的三异丙氧基混合稀土掺杂改性聚苯乙烯 ,利用红外光谱、紫外与可见光吸收光谱、荧光光谱、X射线光电子能谱、扫描电镜等手段对其表征 ,并测定其冲击强度。证明了改性聚苯乙烯中存在着稀土金属离子与苯环的配位作用 ;改性聚苯乙烯的荧光强度比纯聚苯乙烯的高 ,其中以稀土含量为 1 0 %时其荧光强度最高 ;同时改性后聚苯乙烯抗冲性能显著提高 。

Modified polystyrene adulterated with mixed rare earth triisopropoxide was prepared. Modified Polystyrene was characterized by FT-IR spectrum, UV spectrum, fluorescent spectrum, XPS, SEM. The results show that there is of coordination interaction between rare earth ion with phenyl in the modified polystyrene. Modified polystyrene has the higher fluorescence and impact strength than the pure polystyrene.
