软模板法聚苯胺微/纳米管的制备与表征

用化学氧化法中的软模板法,选择同时带有磺酸根(—SO3-)和羧酸根(—COO-)的酸性媒介深黄GG(AMY GG)为掺杂剂,制备出了具有一维微/纳米结构的聚苯胺(PANI)。运用扫描电镜(SEM)、透射电镜(TEM)对产物的微观形貌进行了表征。当盐酸和苯胺摩尔比〔n(HCl)/n(ANI)〕分别为0.5、0.75和1时,得到聚苯胺微/纳米管结构。用傅里叶红外光谱(FTIR)和X射线衍射谱图(XRD)对产物的结构进行了表征,可以看出,AMY GG的两个功能基团—COO-和—SO3-已经掺杂到了聚苯胺分子链上;当n(HCl)/n(ANI)=1时所得产物XRD的衍射峰与其摩尔比为0.2、0.5时所得产物衍射峰有明显差别。

Synthesis and Characterization of Polyaniline Micro/nanotubes by Soft Template Method

Polyaniline(PANI) micro/nanotubes doped with acid mordant yellow GG(AMY GG) with both —COO-and —SO-3 in the molecule as the soft template were prepared by chemical oxidative polymerization.It was found that micro/nanotubes of PANI were obtained when the mole ratio of HCl and aniline was 0.5∶1,0.75∶1 and 1∶1 separately as detected by SEM and TEM.The molecular structures of PANI micro/nanotubes were characterized by FTIR and XRD.It was found that two functional groups(—SO-3 and —COO-) of AMY GG have doped the PANI chain.There was obvious difference between the diffraction peak obtained when n(HCl)∶n(ANI) was 1∶1 and the diffraction peaks obtained when its molar ratio was 0.2 or 0.5.
