▎ 摘　　要

Electric capacitors are manufactured having as dielectric materials cotton fabric-based membranes reinforced with silicone oil (20% vol), carbonyl iron (20% vol), graphene nanoparticles (nGr; Phi = 0%, 4%, 8%, 12%, 16% and respectively 20% vol) and silicone rubber (60%, 56%, 52%, 48%, 44% and respectively 40% vol). The equivalent capacitance (C-p) and resistance (R-p) of the capacitors are measured using an RLC bridge at a frequency of 10 kHz and for magnetic field intensities 0
