摘要
在不加任何还原剂的条件下,采用超声辐射引发溶液聚合制备纳米铁/聚（甲基丙烯酸甲酯-苯乙烯）[P（MMA-St）]复合材料。用XRD、TEM、XPS、FT-IR和TG等分析方法表征结构、热稳定性以及纳米铁与基体P（MMA-St）之间的相互作用。结果表明,纳米铁粒子具有体心立方晶系结构,粒径在20～40nm,且与基体中羰基碳原子和氧原子存在相互作用;纳米铁/P（MMA-St）复合材料热稳定性好,氮气气氛下在660℃开始分解,在850℃的高温下仅损失32%。
Nano-iron/poly（methyl methacrylate-styrene）[P（MMA-St）]composites were synthesized by solution polymerization ultrasonically without addition of reducer.The morphology,microstructure,thermal stability and the interaction between nano-iron and P（MMA-St）matrix of the composites were characterized by means of techniques including X-ray diffractometer（XRD）,transmission electron microscopy（TEM）,X-ray photoelectron spectroscopy（XPS）,Fourier transform infrared spectroscopy（FTIR）and thermal-gravimetry analyzer（TGA）et al.The results showed that the size of nano-iron particles was about 20-40 nm with possessed cubic face-centered structure,and there existed an interaction between nanoiron particlesandCOfromP（MMA-St）matrix;the nano-iron/P（MMA-St）composites was highly thermally stable;the decomposition of it was660 ℃,and about 32%loss weight was measured at 850 ℃ under nitrogen atomosphere.
