| Abstract: | Fe3O4 nanoparticles covered with oleic acid synthesized by coprecipitation were dispersed into MMA,then the composites of PMMA/Fe3O4 were prepared by in situ polymerization.The influences of content of Fe3O4 on Tg of composites,the dissolvability of composites and the molecule weight of PMMA in the composites were studied.The results demonstrated that Tg of composites increased with the increasing of Fe3O4 content.The dissolvability of composites became worse with the enhancement of Fe3O4 content,and became... |
