PS-b-P2VP/Fe3O4纳米复合材料的制备与表征
Preparation and Characterization of PS-b-P2VP/Fe3 O4 Nanocomposites
摘要
Abstract
Oleic acid modified Fe3 O4 nanoparticles( OA-Fe3 O4 ) with uniform particle size were blended with polystyrene-b-poly(2-vinyl pyridine) ( PS-b-P2VP) that had micro-phase separation structure using solution-mixing method. The resultant PS-b-P2VP/Fe3 O4 nanocomposites were superparamagnetic. The results showed that OA-Fe3 O4 nanoparticles were dispersed in the PS phase of PS-b-P2VP, when the mass fraction of OA-Fe3 O4 was 1%, 3%, 5% and 10%. However, when the content of OA-Fe3 O4 was 8%, the dispersion of OA-Fe3 O4 particles in the PS-b-P2VP matrix changed dramatically. In this case, the nanoparticles formed large aggregates, which were dispersed across PS-b-P2VP matrix. Meanwhile the rheological properties of PS-b-P2VP/Fe3 O4 nanocomposites also changed.关键词
