【摘要】 在不同压力条件下用原位聚合法制备了导电聚苯胺薄膜。发现在150MPa~600MPa的甚高压条件下合成的薄膜样品均具有网络状表面形貌,且样品的紫外吸收光谱随压力的增加出现红移现象。实验结果表明样品分子的共轭长度和分子链间的电接触在高压情况下有所增强。这一结论通过引入约化电导率的分析得到进一步证实。更多还原

【Abstract】 The conducting PANI films were synthesized by in situ polymerization under various high pressures.Between the applied pressure range of 150 and 600 MPa, the samples exhibited the network morphology and a Red-shift in UV-visible spectrum as increasing pressure. It was concluded that the conjugate length of the chains in PANI films and the electrical contact between the chains were improves. By using a normalized conductivity, such a conclusion was confirmed further.更多还原
