采用化学氧化法以苯胺为单体,过硫酸铵为氧化剂,磺基水杨酸为掺杂酸合成聚苯胺纳米棒导电材料。考察了单体/掺杂酸摩尔比对聚苯胺形貌与电性能的影响,采用傅里叶红外光谱,XRD粉末衍射表征聚苯胺结构;电化学工作站、四探针研究表明聚苯胺的导电性随掺杂酸/单体摩尔比的增大而增大,单体/掺杂酸摩尔比为2时电导率为1.43S/cm;SEM、TEM表明聚苯胺纳米棒表面粗糙,直径约为100～200nm,长度约为400～700nm,表面附着了1层10～30nm厚的颗粒;并提出了纳米棒可能的形成机理。

Polyaniline nanorods doped with sulfosalicylic acid were prepared by chemical oxidization polymerization with aniline as monomer and ammonium persulfate as oxidant.The influence of mono mer/dopant mole ratio on the electrochemical properties and morphology of synthesized polyaniline.The structure of polyaniline was characterized and studied by FT-IR spectrometric and XRD analysis.Four-point and electrochemical system analysis show that conductivity of polianiline nanorod increase as the increasement of dopant/monomer mole ratio and it reached to 1.43S/cm as the dopant/monomer mole ratio is 0.5.SEM and TEM images indicate that typical nanorods are rough with diameter of about 100-200nm and length of about 400-700nm,respectively.Small 10-30nm granular nanoparticles appear to agglomerate onto the available nanorod surface.At last,the probable formation mechanism of polyaniline nanorod is proposed.
