Patent attributes
This disclosure provides an electrophoretic display system including a first electrode disposed on a substrate and a three-dimensional (3D) carbon-based structure configured to guide a migration of electrically charged electrophoretic ink particles dispersed therein that are configured to be responsive to application of a voltage to the first electrode. The 3D carbon-based structure includes a plurality of 3D aggregates defined by a morphology of graphene nanoplatelets orthogonally fused together and cross-linked by a polymer; and, a plurality of channels interspersed throughout the 3D carbon-based structure defined by the morphology. The plurality of channels includes a plurality of inter-particle pathways and a plurality of intra-particle pathways. Each inter-particle pathway can include a smaller dimension than each inter-particle pathway. A second electrode is disposed on the 3D carbon-based structure. Each 3D aggregate can include any one or more of graphene, carbon nano-onions, carbon nanoplatelets, or carbon nanotubes.
