Abstract

ABSTRACT In this paper, an excellent new hybrid coating including poly(methyl methacrylate) (PMMA), polyaniline (PANI), and magnetite nanoparticles (Fe3O4) was obtained. Fe3O4 nanoparticles were synthesized using coprecipitation method, and then magnetite nanoparticles have been dispersed into the PANI to increase compatibility with PMMA. Also, PANI/Fe3O4 nanocomposites were synthesized through in situ emulsion polymerization, and then PMMA/PANI/Fe3O4 hybrid coating was successfully synthesized using batch emulsion polymerization method. Structure, morphology and thermal stability of the samples were characterized using Fourier transform infrared, X-ray diffraction, scanning electron microscopy, transmission electron microscopy, and thermal gravimetric analysis (TGA). The synthesized samples were well distributed with an average diameter smaller than 20 nm. Microscopy and X-ray photoelectron spectroscopy results illustrated a great dispersion of magnetite nanoparticles in hybrid matrix. Moreover, the TGA results demonstrated that the PMMA/PANI/Fe3O4 hybrid coating nanoparticle is an excellent hybrid coating with high thermal resistance. GRAPHICAL ABSTRACT

新型导电杂化涂层PMMA/PANI/Fe3O4的制备

摘要本文制备了一种由聚甲基丙烯酸甲酯(PMMA)、聚苯胺(PANI)和磁铁矿纳米颗粒(Fe3O4)组成的新型高性能杂化涂层。采用共沉淀法合成了Fe3O4纳米颗粒，并将磁铁矿纳米颗粒分散到聚苯胺中以提高与PMMA的相容性。采用原位乳液聚合法制备了PANI/Fe3O4纳米复合材料，并采用间歇乳液聚合法制备了PMMA/PANI/Fe3O4杂化涂层。采用傅里叶变换红外、x射线衍射、扫描电镜、透射电镜和热重分析(TGA)对样品的结构、形貌和热稳定性进行了表征。合成的样品分布均匀，平均直径小于20 nm。显微镜和x射线光电子能谱分析结果表明，磁铁矿纳米颗粒在杂化基质中具有较强的分散性。此外，TGA结果表明，PMMA/PANI/Fe3O4杂化涂层纳米颗粒是一种优异的高热阻杂化涂层。图形抽象
