樟脑磺酸原位聚合聚苯胺的性能研究

Property of polyaniline redoped with camphor sulfonic acid

用樟脑磺酸 (HCSA)代替盐酸经原位聚合制备了樟脑磺酸掺杂聚苯胺 (PANI .HCSA ) ,并用红外、紫外和荧光光谱等表征。研究了樟脑磺酸掺杂的聚苯胺在不同的有机溶剂中的溶解性及可见 紫外光的吸收现象。结果表明 :PANI .HCSA具有良好的导电性和溶解性 ,红外光谱显示聚苯胺苯环上有CSA-基团。UV Vis吸收光谱表明 ,在不同的有机溶剂中 ,溶剂、聚苯胺、樟脑磺酸之间有不同的相互作用 ,从而使其体系具有不同的UV Vis吸收光谱。PANI .HCSA荧光光谱与PANI荧光光谱相比 ,荧光强度降低 ,并红移至 40 0nm。

In this paper, Polyaniline doped with camphor sulfonic acid was prepared. The results show that it has good conductivity and high solubility. UV Vis spectrum indicates that there were different interactions among solvent, PANI , camphor sulfonic acid in various organic solvents. FTIR spectrum reveales existence of CSA - groups in the benzenoid rings of PANI,and absorption bands of PANI.HCSA have red shift compared to PANI.
