摘要

以苯胺为前驱体,在室温下采用简单的化学氧化聚合法制备了聚苯胺(PANI)非纤维。采用H3PO4掺杂剂合成。利用扫描电镜(SEM)、红外光谱(FTIR)和紫外可见光谱(UV)对其结构、化学基团和电子跃迁进行了研究。研究了不同浓度掺杂H3PO4的DL - PLA/PANI-ES复合膜的甲烷气体响应。在500ppm时,甲烷气体响应百分比(%)为9%。

Inorganic Doped Dl-Polylactide Polyaniline Based Composite for Methane (Ch4) Gas Sensing
Polyaniline (PANI) nonofibriles have been successfully synthesised by simple chemical-oxidation polymerization method using aniline as a predecessor at room temperature. It was synthesized using H3PO4 dopants. The structure, chemical groups, and electronic transition were investigated by SEM, FTIR, and UV Visible. We present the methane gas response of as-prepared H3PO4 doped DL−PLA/PANI-ES composite film at different concentration. The percentage (%) methane gas response was found to be 9 % at 500ppm.
