原位聚合纳米FeNi_3/聚苯乙烯复合材料的制备与特性

采用固-液反应法制备了纳米FeNi3。将纳米FeNi3与一定量油酸、SDS混合均匀，并分散到苯乙烯（st）单体中，用原位聚合的方法制备了纳米FeNi3／PS复合材料。利用XRD、TEM、FTIR及SEMTG—DSC分别研究了所得纳米FeNi3合金的性能、复合材料的结构及纳米FeNi3在PS中的分散情况。研究结果显示：加压加热的固相反应和液相反应，可制得粒度为65～125nm的具有球形形貌的体心立方纳米FeNi3合金粉体；原位聚合制备的纳米FeNi3／Ps复合材料中纳米FeNi3合金在PS中分散均匀；随着掺杂量的增加，红外振动吸收峰的强度变弱。

Study on Thermodynamics Parameters of Iron-nickel Nanoparticles/polystyrene Composites

Iron-nickel alloy nanoparticles were obtained by a solid-liquid reaction method.A uniform mixture with iron-nickel alloy nanoparticles,olic acid and SDS was added into styrene monomer and dispersed with a stirrer.The iron-nickel alloy nanoparticles/PS composites were synthesized via in situ polymerization method.XRD,TEM,SEM and FTIR were respectively used to measure the properties of iron-nickel alloy nanoparticles,the microstructure of as-prepared composites samples and the distribution of iron-nickel allo...
