To elucidate the response of different solvents such as isopropyl-alcohol (IPA) and acetone for polyaniline-emeraldine-base (PANI), the charge transport mechanism is investigated as a function of temperature in the presence of different solvents. From SEM and XRD characterization, it is noted that each solvent improves the surface smoothness and negligible solvent traces were observed in the final thin-film devices. It is further observed that all devices follow space-charge-limited-current (SCLC) model to define their electrical responses. Conductivity was measured directly through four-probe method, while mobility was estimated from SCLC model and then both conductivity and mobility of PANI are compared with the given solvent at different temperatures. Similarly, it is also realized that the IPA solvent improves conductivity, mobility and degradation of PANI thin-film due to complex behaviour of solvent induced self-organization of molecular chains and reduction of residual tr...

溶剂诱导的在较高温度下传导聚合物的电荷传输机制

为了阐明不同溶剂（例如异丙醇（IPA）和丙酮）对聚苯胺-翡翠碱（PANI）的响应，研究了在不同溶剂存在下电荷输送机制随温度的变化。从SEM和XRD表征可以看出，每种溶剂都能改善表面光滑度，并且在最终的薄膜器件中观察到的溶剂痕迹可忽略不计。进一步观察到，所有设备都遵循空间电荷限制电流（SCLC）模型来定义其电响应。通过四探针法直接测量电导率，同时根据SCLC模型估算迁移率，然后将PANI的电导率和迁移率与给定溶剂在不同温度下进行比较。同样，我们也意识到IPA溶剂可提高电导率，
