▎ 摘　　要

NOVELTY - Polymer composition comprises 5-99 wt.% polymer base resin, 0-40 wt.% filler and 0.01-10 wt.% graphene, where the polymer composition exhibits dielectric constant, which is 1.1 times greater than substantially similar composition in absence of graphene, where the concentration of all components is not greater than 100 wt.%, and concentrations are based on total weight of composition. USE - The polymer composition is useful in an article, such as a component of electrical insulation, an electrical enclosure, a lamp housing or a dielectric film for capacitor (claimed), and as an electrically insulating material. ADVANTAGE - The polymer composition exhibits improved dielectric strength while maintaining mechanical performance.
