中文摘要:
      以过硫酸铵或2,3-二氯-5,6-二氰基-1,4-苯醌(DDQ)为氧化剂,单一手性樟脑磺酸作为诱导酸及掺杂剂,在有机溶剂、水-有机溶剂和水溶剂体系中,采用四种不同方法分别进行了单一手性聚苯胺纳米纤维合成研究。通过扫描电子显微镜(SEM)、紫外可见光谱(UV-VIS)、X射线衍射(XRD)和圆二色谱(CD)等手段对自组装法、界面聚合法、低聚物辅助法与二次掺杂法等四种方法制备得到聚苯胺纳米纤维的形貌、结构及光学活性进行表征,对比分析后发现四种方法合成的掺杂态聚苯胺纳米纤维形貌、结构相似,但溶剂体系会影响最终产物的光学活性:水溶剂、有机溶剂体系中,得到的聚苯胺纳米纤维光学活性相反。
英文摘要:
      Single chiral polyaniline was prepared in organic, aqueous and aqueous-organic solvents, by using ammonium persulphate and DDQ as oxidant and single chiral camphor sulfonic acid as induced acid and dopant. Four methods of the chemical synthesis of single chiral polyaniline nanofibers, self-assembly, interfacial polymerization method, oligomer-assisted method and secondary doping method were studied and compared. The morphology, structure and optical activity of polyaniline were characterized by Scanning electron microscopy (SEM), Ultraviolet-visible spectroscopy (UV-VIS), Circular dichroism(CD) and X-ray diffraction (XRD). The results showed that the morphology and structure of polyaniline synthesized by the four methods were similar. However, the chiral properties of the PANI were opposite in aqueous solvent and organic solvent systems.
