十二烷基苯磺酸钠胶束体系中聚苯乙烯α-Fe2O3复合纳米粒子的制备
Preparation of Polystyrene/α-Fe2O3 Nano-Particles in SDBS Micellar System
【Abstract】 Nanoparticles of polystyrene/α Fe 2O 3 composites were prepared by method of insertion in sodium dodecylbenzene sulfonate(SDBS) micellar system. The orange α Fe 2O 3 particles of about 6 nm were first prepared from 0 25 mol/L FeCl 2 and (NH 3) 2CO 3 in 0.1% surfactant solution at pH=4, 105 ℃ for 10 h. The title nanoparticles were prepared then in conditions of SDBS∶ styrene∶H 2O(mass fraction)=0 1∶1∶9, 85 ℃, 8 h, using ammonium persulfate(APS) as an initiator. The composite nanoparticles sized in 20~50 nm and showed magnetic property.
