Synthesis and characterization of poly(1-naphthylamine) nanopowders

采用界面聚合法合成了聚(1-萘胺)纳米颗粒。利用红外光谱(FT-IR),紫外可见吸收光谱(UV-vis),电子扫描显微镜(SEM),投射电镜(TEM),X射线衍射(XRD),循环伏安(cyclic voltammogram)等测试方法,对聚合物进行了表征并对聚合物形貌、结构及性能进行了初步探讨。结果表明,界面聚合法合成的聚(1-萘胺)呈现直径在100nm内的颗粒状分布;XRD结果显示,聚(1-萘胺)为半结晶态聚合物;界面聚合法合成的聚(1-萘胺)具有一定的电化学活性。

Poly （1- naphthylamine） nano powders were synthesized by using interracial synthesis method. The FTIR spectra, UV-vis absorption spectra and X-ray diffraction patterns were used to characterize the molecular structures of the polymer. The morphologies of powders were studied by using SEM and TEM. Voltammetric study was done to investigate the electrochemical behaviors of Poly （1- naphthylamine）. The structure, crystallinity, morphology and electrochemical activity of the polymer were discussed. The results showed that Poly （1- naphthylamine） particles appeared as nano powder in the micrograph, their diameter was within 100 nanometers. X-ray diffraction patterns showed the crystallinity of Poly （1- naphthylamine） was not good. Voltammetric study indicated that the Poly （1- naphthylamine） synthesized by interracial synthesis method had better electrochemical activity.
