The paper is devoted to the investigation of the physical properties of graphite nanoplatelets / epoxy composite materials with a modified level of interface interaction due to pre-irradiation of the filler with ultraviolet light. The influence of interface interaction at the filler / matrix interface in polymer-carbon composite materials on their electrodynamic properties is determined, which is the basis for the development of composite materials with an adjustable set of physical properties. By analyzing within the model, which takes into account the volume fraction of the interface region, it has been shown that the increase of dielectric constant in composites, where pre-irradiated with ultraviolet light graphite nanoplatelets were used as a filler, occurs due to an increase of the dielectric constant of the interface layer, which is associated with a change in the chemical composition of the surface of graphite nanoplatelets. |
