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/Fe_(3)O_(4)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,Fe_(3)O_(4)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Fe_(3)O_(4)后,纳米银线复合材料具有良好的导电性。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 Fe_(3)O_(4)/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)=4.9 mol/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 0.18 g,T=180℃,and T=8 h,Fe_(3)O_(4)/silver nanowires composites formed a regular network structure to enhance its conductivity.It was found that Fe_(3)O_(4) nanoparticles were supported on the surface of silver nanowires.Lastly,the conductivity of composites were characterized.The conductivity results showed that after coating of Fe_(3)O_(4) nanoparticles,silver nanowires comosites remained good conductivity.
