Image dataset for the paper “quantifying electrical network interconnectivity using graph theory”

Optical microscopy image dataset of multilayer graphene sheet (GS)/epoxy nanocomposites at 8 filler concentrations (1–8 wt.% in steps of 1 wt.%), comprising 800 micrographs (100 per concentration) acquired to quantify electrical network interconnectivity via graph theory. Images were recorded in a 24-bit RGB color format with a resolution of 640×480 pixels, resulting in a calibrated scale of 2.08 µm/pixel. Images were acquired using a SONY® XC-75 camera mounted on a LEICA DMLM optical microscope (Wetzlar, Germany).多层石墨烯片（graphene sheet, GS）/环氧树脂纳米复合材料的光学显微图像数据集，涵盖8种填料浓度（1~8 wt.%，步长为1 wt.%），包含800张显微图像（每种浓度对应100张），该数据集用于通过图论量化电网络的连通性。图像采用24位RGB色彩格式采集，分辨率为640×480像素，校准标尺为2.08 µm/像素。图像采集使用搭载于徕卡（LEICA）DMLM光学显微镜（德国韦茨拉尔）的索尼（SONY®）XC-75相机完成。
