摘要

采用两种方法首次制备了基于多苯恶嗪(phhoa)和铁纳米颗粒的杂化金属-聚合物纳米复合材料:一是在异丙醇水溶液中原位氧化聚合苯恶嗪(PhOA)，同时存在铁纳米颗粒;在惰性气氛中，在FeCl - 3 Â·6h2o存在下，在400 - 450 Â°Ði下进行红外加热的PPhOA的化学转变。采用傅里叶变换红外光谱(FTIR)、x射线衍射(XRD)、透射电子显微镜(TEM)、原子吸收光谱(Ð′Ð′S)、元素分析、差示扫描量热法(DSC)、热重分析(TGA)以及振动样品磁强计对所获得的fe3o / phhoa杂化纳米材料进行了表征。研究了纳米复合材料的化学结构、相组成、磁性和热性能与合成条件的关系。

Formation Features of Hybrid Magnetic Materials Based on Polyphenoxazine and Magnetite Nanoparticles

Hybrid metal-polymer nanocomposite materials based on polyphenoxazine (PPhOA) and Fe 3 O 4 nanoparticles were obtained for the first time via two methods: in situ oxidative polymerization of phenoxazine (PhOA) in an aqueous solution of isopropyl alcohol with nanoparticles of Fe 3 O 4 being present; chemical transformations of PPhOA subjected to IR heating at 400â€“450 Â°Ði in the presence of FeCl 3 Â·6H 2 O in an inert atmosphere. Obtained hybrid Fe 3 O 4 /PPhOA nanomaterials were characterized by means of Fourier transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD), transmission electron microscopy (TEM), atomic absorption spectrometry (ÐÐS), elemental analysis, differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), as well as by vibrating sample magnetometry. The chemical structure, phase composition, magnetic and thermal properties of obtained nanocomposites were investigated in relation to the synthesis conditions.
