摘要: 采用原位聚合法制备了苯乙烯丙烯酸正丁酯共聚物(PSb)/四氧化三铁(Fe3O4)纳米复合材料,并通过傅里叶变换红外光谱仪、透射电子显微镜、X射线衍射仪、综合物理特性测量系统对该复合材料的结构与性能进行了表征。结果表明:Fe3O4纳米粒子直径约9 nm,同时能较均匀地分散在PSb中且无明显团聚;该复合材料具有良好的超顺磁性;XRD图谱中Fe3O4特征峰随着复合材料中Fe3O4含量的增加而逐渐增强;同时Fe3O4纳米粒子的加入提高了PSb的热稳定性。

Abstract: Poly(styrene-co-butyl acrylate) (PSb)/Fe3O4 nanocomposites were prepared via in-situ polymerization. Microstructure and properties of the nanocomposite were characterized by Fourier-transform infrared spectroscopy, transmission electron microscopy, X-ray diffraction and physical performance measurements. The results indicated that Fe3O4 nanoparticles had a diameter around 9 nm, and they were uniformly dispersed in the PSb matrix without any aggregation. These nanocomposites were found to exhibit a super paramagnetism feature. The incorporation of Fe3O4 nanoparticles into PSb could enhance the thermal stability of the nanocomposites.
