Abstract

A novel poly(1,4-diaminonaphthalene) was synthesized from the monomer 1,4-diaminonaphthalene at the nanoscale via an oxidative polymerization method. The reaction was conducted in an acidic (HCl) medium under an ultrasound homogenizer at 0 °C, while potassium persulfate was used as a radical initiator. This polymer has been characterized using various techniques, including FTIR, UV-Vis spectroscopy, thermogravimetric analysis (TGA), scanning electron microscopy (SEM), NMR analysis, and electron paramagnetic resonance (EPR) methods. The nanopolymers were found to be thermally stable up to 200 °C. EPR data further substantiated the presence of unpaired electrons on the nitrogen atoms within the polymer backbone.

过硫酸钾纳米聚(1,4-二氨基萘)的合成与表征
以1,4-二氨基萘为单体,采用氧化聚合的方法在纳米尺度上合成了新型聚1,4-二氨基萘。反应在酸性(HCl)介质中进行,超声均质机温度为0℃,过硫酸钾作为自由基引发剂。该聚合物已经使用各种技术进行了表征,包括FTIR, UV-Vis光谱,热重分析(TGA),扫描电子显微镜(SEM),核磁共振分析和电子顺磁共振(EPR)方法。研究发现,纳米聚合物在高达200°C的温度下具有热稳定性。EPR数据进一步证实了聚合物主链内氮原子上存在不成对电子。
