摘要

为了研究纳米银线为基体的复合材料的性能,分别采用乳液聚合法和溶剂热法制备了聚苯乙烯(PS)/纳米银线(PS/纳米Ag线)复合材料和PS/Fe3O4复合材料。通过X射线衍射仪(XRD)和傅里叶红外光谱仪(FT-IR)分析了纳米银线基复合材料的结构和官能团,采用扫描电镜(SEM)对纳米银线基复合材料的形貌进行了分析。结果表明,当聚乙烯吡咯烷酮(PVP)与十二烷基硫酸钠(SDS)的质量比为1∶1、过硫酸钾(KPS)浓度为4.9mol/L时,在直径30~100nm,长度8~12μm纳米银线的表面负载了梅花枝状的PS,可以实现PS在纳米银线表面的有效复合。当聚丙烯酰胺(PAM)质量为0.18g,温度为180℃,反应时间8h时,Fe3O4纳米粒子在纳米银线表面实现了成功负载。最后,对复合材料的电导性能进行了表征。相对于包覆PS,在表面包覆Fe3O4后,纳米银线复合材料具有良好的导电性。

Abstract

In order to study the properties of silver nanowires based composite materials,polystyrene(PS)/silver nanowires composite materials were prepared by emulsion polymerization,and prepared Fe3O4/silver nanowires composite materials by solvent thermal method,respectively.The structure and functional group of the composites were analyzed by X-ray diffraction (XRD) and fourier transform infrared spectrum (FT-IR),and the morphology of the composites were analyzed by scanning electron microscope (SEM).The results showed that when m(PVP)∶m(SDS)=1∶1 and C(KPS)=4.9mol/L,plum blossom branch polystyrene was successfully loaded on silver nanowires with a diameter of 30~100 nm and a length of 8~12μm.When the mass of polyacrylamide(PAM) was 0.18g,T=180℃,and T=8h,Fe3O4/silver nanowires composites formed a regular network structure to enhance its conductivity.It was found that Fe3O4 nanoparticles were supported on the surface of silver nanowires.Lastly,the conductivity of composites were characterized.The conductivity results showed that after coating of Fe3O4 nanoparticles,silver nanowires comosites remained good conductivity.
