摘要： The present invention relates to a self-assembled composite of carbon nitride and graphene oxide, and in particular, to including a self-assembled composite prepared by heat treating a mixed solution dissolving melamine, tri-thiocyanuric acid and graphene oxide (GO) in a positive electrode of a lithium-sulfur battery to suppress elution of lithium polysulfide. According to the present invention, the self-assembled composite containing a pyridinic group in large quantities and having improved conductivity adsorbs lithium polysulfide eluted from a positive electrode during charge and discharge and performs a role of preventing diffusion of the lithium polysulfide, and therefore, lithium-sulfur battery capacity and lifecycle properties can be enhanced by suppressing a shuttle reaction.

摘要： 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.

摘要： Process for producing pristine graphene nanoplatelets, comprising the expansion of flakes of intercalated graphite and the collection thereof in water with formation of a dispersion in the substantial absence of surfactants, followed by an exfoliation and size reduction treatment carried out using ultrasonication of the aqueous dispersion or using high pressure homogenization thereof in a high shear homogenizer. A dispersion of pristine graphene is obtained in the form of nanoplatelets, at least 90% of which have a lateral size (x, y) from 50 to 50,000 nm and a thickness (z) from 0.34 to 50 nm, having a C/O ratio ≥100:1 and a high electrical conductivity.
