| 摘 要： | 以钛酸酯偶联剂在无水乙醇中对纳米氧化铕进行表面修饰,分别测定了处理好的样品的粒径及分布、在二氧六环中的沉降稳定性以及在聚丙烯中的分散性。结果表明:表面修饰有利于纳米氧化铕在聚丙烯中的分散,其中以10%钛酸酯处理的效果最佳;处理后样品的红外光谱表明,纳米氧化铕与偶联剂发生了化学键合作用,它们之间并不是简单的物理包覆。 |

| Abstract: | The europia nanoparticles were treated by titanate coupling agents in the alcohol.Its particle size and distribution,stability in dioxane and dispersion in polypropylene after surface modification were measured.The results showed that the optimal content of coupling agent mass ratio to Eu2O3 particles is 10%,and achieved less aggregation,good dispersion in polypropylene.The infrared spectrum of sample treated showed that new chemical bond between Eu2O3 and coupling agent formed and the effect was not a simply physical coating. |
