Reduced Graphene Oxide Conductivity Gradient for Electric Field Smoothing

The patent applies local quality by creating a material with spatially varying electrical properties. The reduced graphene oxide material has a gradient structure where the degree of reduction varies across the material, resulting in different conductivity and permittivity values at different locations. This allows the material to have high conductivity at interfaces (reducing field concentration) while maintaining insulating properties in the bulk, thus resolving the contradiction between functional differentiation and electrical breakdown risk

The patent utilizes parameter changes by systematically varying the degree of reduction of graphene oxide across the material structure. By controlling the reduction level spatially, the material achieves a continuous gradient in electrical conductivity and permittivity. This parameter variation enables the material to adapt its electrical properties to different functional requirements while preventing electric field concentration that would lead to breakdown

The material implements local quality through a gradient structure where the degree of reduction of graphene oxide varies spatially. This creates regions with different electrical properties within a single continuous material, allowing the material to provide both high conductivity where needed (at interfaces) and maintain insulating properties in other regions, thus achieving functional differentiation without compromising field distribution uniformity

The patent employs composite material principles by creating a reduced graphene oxide material with non-uniform composition. The spatial variation in reduction degree creates a composite-like structure within a single material phase, where different regions effectively function as different materials. This internal composite structure enables the material to achieve both functional differentiation and stable field distribution simultaneously
