摘要
以苯胺为单体,过硫酸铵为氧化剂,在正反方向磁场辅助下,采用界面聚合法制备聚苯胺(PANI)。利用红外光谱(FT-IR)和扫描电镜(SEM)对聚苯胺的分子结构和形貌特征进行表征。结果表明:在有/无磁场辅助下制备的聚苯胺,其结构和形貌存在一定的差异。特别是正反方向磁场辅助下制得的聚苯胺呈现花瓣状的新形貌特征。
Polyaniline(PANI)was synthesized by interfacial polymerization with aniline as monomer and ammonium persulfate as oxidant.The molecular structure and morphology of the PANI were characterized by FT-IR spectra and scanning electron microscope(SEM).The results showed that the structure and morphology of PANI were different in the presence and absence of positive and opposite magnetic field.Especially,PANI synthesized in the presence of positive and opposite magnetic field showed a new petaline structure characteristics.
