Abstract

Oxidative polymerization of aniline is for the first time conducted in aqueous solutions of polynaphthalene sulfonic acid (PNSA) at different ratios of the concentrations of aniline and PNSA. The polymerization is studied by in situ spectroscopy in the UV-vis and near-IR regions. The films of water-dispersible complexes of polyaniline (PANI) with PNSA are obtained by spraying. The electron structure, morphology, and sensor (ammonia) properties of the films of PANI–PNSA complexes are studied for the first time. To increase the stability of the sensor properties under the conditions of humidity close to 100%, the effect of their treatment with aqueous solutions of sodium, calcium, strontium, and aluminum chlorides is studied.

金属阳离子性质对聚苯胺与聚萘磺酸配合物薄膜光学传感器性能的影响

首次在苯胺与聚萘磺酸（PNSA）不同浓度比的水溶液中进行了苯胺的氧化聚合。用紫外-可见和近红外原位光谱研究了聚合反应。采用喷雾法制备了聚苯胺（PANI）与聚苯胺（PNSA）的水分散配合物薄膜。本文首次研究了聚苯胺- pnsa配合物薄膜的电子结构、形貌和传感器（氨）性能。为了提高传感器在接近100%湿度条件下性能的稳定性，研究了用氯化钠、氯化钙、氯化锶和氯化铝水溶液处理传感器的效果。
