Abstract

This paper reports that PPy/PANI blends are successfully synthesized from solution process. For high performance optoelectronic devices, understanding the electrical and optical properties of materials should be significant. The aim of this work is to study the polymer-blend morphologies as well as the electrical and optical properties of materials. The polymer blends were prepared as a function of composition. Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy with energy dispersive X-ray analysis (SEM-EDX), ultraviolet-visible (UV–Vis) spectroscopy, photoluminescence (PL) and current-voltage (IV) characteristics techniques were applied for characterizing the PPy/PANI blends. The PPy/PANI blend is a semiconductor by showing the conductivity in the range of 10–6 to 10–3 S/cm at room temperature. The result determines the optical band gap of each blend with different composition, providing the optical band gap of the blends at the range of 1.53–1.95 eV. Finally, the electrical transport and the chemical composition of the PPy/PANI blends were characterized.

聚吡咯和聚苯胺共混物的电学和光学性质

摘要

本文报道PPy / PANI共混物是成功地从溶液过程中合成的。对于高性能光电器件,了解材料的电学和光学特性应该很重要。这项工作的目的是研究聚合物共混物的形态以及材料的电学和光学性能。制备聚合物共混物作为组成的函数。傅里叶变换红外光谱(FTIR),具有能量色散X射线分析(SEM-EDX)的扫描电子显微镜,紫外可见(UV-Vis)光谱,光致发光(PL)和电流电压(IV)采用了表征技术来表征PPy / PANI混合物。PPy / PANI混合物在室温下的电导率范围为10 –6至10 –3 S / cm,是一种半导体。结果确定了具有不同组成的每种共混物的光学带隙,使共混物的光学带隙在1.53至1.95 eV的范围内。最后,表征了PPy / PANI共混物的电迁移和化学组成。
