摘要

结合,60,Co γ射线辐照与分散聚合，分别通过两步法和一步法，在常温常压下，成功地合成了γ−Fe,2,O,3,/聚苯乙烯（γ−Fe,2,O,3,/PSt）磁性复合微球，并对复合微球的形成机理进行了探讨。用透射电子显微镜（TEM）、电子衍射（ED）、X射线衍射（XRD）、付里叶变换红外（FTIR）光谱对样品进行表征和研究。实验结果表明，产品为多个γ−Fe,2,O,3,纳米粒子均匀地分散于PSt微球中的 γ−Fe,2,O,3,/PSt磁性复合微球，体系中的丙烯酸（AA）对磁性复合微球的形成起到了非常重要的作用。

Abstract

By combining dispersion polymerization and γ-ray irradiation, γ-Fe,2,O,3,/polystyrene (γ-Fe,2,O,3,/PSt) magnetic composite microspheres were produced at room temperatures under ambient pressure ,via, one-step method or two-steps method. Formation mechanisms of the magnetic composite microspheres were studied. The magnetic composite microspheres were characterized and studied with transmission electron microscope (TEM), electron diffraction (ED), X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy. The results show that the magnetic composite PSt microspheres containing homogeneously dispersed γ-Fe,2,O,3, nanoparticles and the acrylic acid in the system played an important role in the synthesis of the magnetic composite microspheres.
