PMMA/P(AN-MMA)纳米复合粒子的制备与形貌表征

Synthesis and Morphology Characterization of PMMA/PAN-PMMA Nano Composite Particles

采用种子乳液聚合的方法制备PMMA/P(AN_MMA)纳米复合粒子 ,在第二阶段聚合过程中分别采用水溶性引发剂、油溶性引发剂以及氧化还原引发体系 ,通过透射电子显微镜 (TEM)来观察复合乳胶粒子的形态结构 ,得到的PMMA/P(AN_MMA)纳米复合粒子为半球形结构 ,与热力学理论预测结果一致。

Study on the effect of different initiators on the structure of PMMA/P(AN-MMA)nano composite particles.Three types of initiators,potassium persulfate(KPS),azobisiobutyrinitrile (AIBN)and text-butyl hydroperoxide(C 4H 10 O 2)/FeSO 4 were used in the second-stage polymerization,the results showed that the morphology structure of PMMA/P(AN-MMA) nano composite particles by seeded emulsion polymerization,at the thermodynamics equilibrium condition,was hemisphere structure in line with the thermodynamics analysis.
