摘要
采用化学氧化法,以苯胺为单体,过硫酸铵为氧化剂,在不同La3+浓度下于酸性介质中合成了聚苯胺-镧。研究了La3+浓度对产物电导率的影响,并通过红外光谱、紫外可见光谱和X射线衍射谱等研究了La3+浓度对聚苯胺结构的影响。结果表明,当溶液中La3+浓度为0.3 mol/L时,所得聚苯胺-镧具有较高的室温电导率;紫外和红外光谱表明,La3+与聚苯胺链上的N原子存在相互作用。
Polyaniline-La （PANI-La） was synthesized in a solution containing 0. 3 mol/L aniline, 2.0 mol/L HCl, and a certain amount of LaCl3, using peroxydisulphate as an oxidant. The effect of the La^3＋ concentration on the conductivity and structure of PANI-La was studied. It was indicated that when the concentration of La^3＋ was 0. 3 mol/L, the PANI-La had higher conductivity at room temperature. UV and FT-IR spectra showed that there was the interaction between La^3＋ and the PANI chains.
