| 摘 要： | 论文采用Ce4 和PEG组成的大分子引发剂引发丙烯腈单体AN聚合,合成嵌段共聚物PAN-PEG-PAN,并用DSC对PEG-b-PAN的热性能进行了研究。TEM结果表明,嵌段共聚物PAN-PEG-PAN在选择性溶剂中的自组装可以得到纳米尺度的胶束粒子。论文还研究了嵌段共聚物通过原位聚合和自组装两种方法对SiO2纳米粒子进行包覆的情况。通过TEM可以得到,相同条件下在自组装过程中对SiO2纳米粒子进行包覆情况较好。

| Abstract: | Ce4 and PEG can be used as a macromolecule initiator in the polymerization of AN,forming PAN-PEG-PAN.Studies on the thermol-properties of this block copolymer were carried on using DSC.Also,TEM provides that in selective solvent PAN-PEG-PAN can assemble together,so micelles and their size are obtained.According to other articles,Nano-SiO2 can be coated as a core inside micelles.In this paper,two methods are used to study it and find that the self-assembly way is much better. |
