摘要: In the present work, electrical and mechanical properties of epoxy nanocomposite materials were studied. The hydrophobicity insulating material was analyzed through contact angle measurement. diffusion coefficients with different percentage clay in nanocomposites calculated. exfoliation characteristics Wide Angle X-ray Diffraction (WAXD) studies. thermal behaviour by carrying out Thermo gravimetric Differential Thermal Analysis (TG-DTA) tensile test, flexural impact test carried to understand clay. Heat deflection temperature measured stability for intermittent variation. Dynamic Mechanical (DMA) results indicated that storage modulus increases small amount resin. activation energy calculated from DMA results. short time insulation breakdown studies indicate voltage nano Also, it shown positive DC is higher than negative voltage, irrespective
