Nanocomposite materials consisting of polymer matrices and nano-sized fillers have fascinated scientists with their superior functional properties, attained at relatively low filler loading. In this work, nanocomposite films of poly(methyl methacrylate) (PMMA)-reinforced with different concentrations of partially reduced graphene oxide/silver (rGO/Ag) hybrid were prepared in two different solvents following an ex situ chemical method. By employing solvent casting, all the samples were prepared as free-standing films. The structural and morphological characterisations of a GO/Ag hybrid and the as-prepared film samples were done with different tools such as x-ray diffraction (XRD), UV–Vis absorption spectroscopy, Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy and electron microscopy (SEM and TEM). Chemical microanalysis of the nanohybrid was carried out by energy-dispersive x-ray (EDX) spectroscopy. Dielectric properties of these films have been carried out at room temperature in the frequency range of 100 Hz–2 MHz using an LCR meter, and these films show considerable changes in their properties when loaded with GO/Ag hybrid nanocomposites. The filler and solvent-dependent properties shown by the free-standing films make them a promising candidate for the fabrication of flexible energy storage devices.

由聚合物基体和纳米级填料组成的纳米复合材料以其较低的填料含量获得了卓越的功能特性，吸引了科学家的注意。在这项工作中，采用异位化学方法在两种不同的溶剂中制备了由不同浓度的部分还原的氧化石墨烯/银（rGO / Ag）杂化剂增强的聚甲基丙烯酸甲酯（PMMA）增强的纳米复合膜。通过使用溶剂流延，将所有样品制备为自支撑膜。GO / Ag杂化物和制备的薄膜样品的结构和形态表征是使用不同的工具完成的，例如X射线衍射（XRD），UV-Vis吸收光谱，傅里叶变换红外光谱（FTIR），拉曼光谱和电子显微镜（SEM和TEM）。纳米杂化体的化学微分析通过能量色散X射线（EDX）光谱进行。这些薄膜的介电性能已使用LCR计在室温下于100 Hz–2 MHz的频率范围内进行了测试，并且在负载GO / Ag杂化纳米复合材料后，这些薄膜的性能发生了显着变化。自支撑薄膜所显示的与填料和溶剂有关的特性使其成为制造柔性储能装置的有前途的候选者。
