Abstract

H(2)SO(4) doped polyaniline (PANI) has synthesized by chemical oxidation method. The prepared Polyaniline were annealed at 150 °C, 200 °C and 250 °C for 30 min in vacuum. Crystal size, percentage of crystallinity, total percentage of crystallinity properties of untreated and heat treated PANI samples were studied by using X-ray diffraction pattern. The molecular structure of untreated and heat treated samples were examined by using Fourier transform infrared spectrophotometer. UV study shows π-π* transition of untreated and heat treated of polyaniline were found at 328 and 636 nm. The peak at 636 nm reveals the extension of conjugated polymer. Thermal properties of untreated and heat treated PANI sample measured by using thermo gravimetric analysis and differential scanning calorimetric spectroscopy.

摘要

采用化学氧化法合成了硫酸掺杂聚苯胺（PANI）。将制备好的聚苯胺在真空中于150℃、200℃和250℃退火30分钟。通过X射线衍射图谱研究了未处理和热处理的聚苯胺样品的晶体尺寸、结晶度百分比、总结晶度特性。使用傅里叶变换红外光谱仪检测未处理和热处理样品的分子结构。紫外研究表明，未处理和热处理的聚苯胺的π-π*跃迁分别出现在328纳米和636纳米处。636纳米处的峰表明共轭聚合物的延伸。使用热重分析和差示扫描量热光谱法测量未处理和热处理的聚苯胺样品的热性能。
