摘要
采用四因素三水平正交设计法,研究了硫酸掺杂导电聚苯胺(p型)的热处理优化条件,结果表明最优热处理条件为:175℃、8h,此时聚苯胺的电导率和结晶度最大,分别为4.926S/cm和28.94%。通过X射线衍射分析(XRD)、差热分析(DTA)和电导率测试等手段,对其进行表征分析,并比较热处理前后聚苯胺太阳能电池性能。结果表明,经热处理后,掺杂聚苯胺分子构型变为扩展线圈,结晶度、电导率和热稳定性得到很大提高,也使得组装的聚苯胺太阳能电池性能较未热处理前大为提高。
The optimum condition of heat treatment of conductive polyaniline doped by H2SO4（p-type PANI） was confirmed by orthogonal design 3 levels with 4 factors. The characterization of PANI was studied by X-ray diffraction（XRD）, differential thermal analysis（DTA） and conductivity testing method. The optimum condition of heat treatment of PANI doped by H2SO4 is 175 ℃ and 8 hours, and at this condition, the conductivity and crystallinity is reached at 4.926 S/cm and 28.94% respectively. The results show that crystallinity, conductivity, and thermal stablility of PANI are enchanced due to the change of expanding coil configuration for doped PANI molecular chain by heat treatment, which improves the performance of PANI solar cell.
