摘要： Disclosed are dispersed graphene sheets, ribbons, graphene molecules and the like which are pristine in the plane, i.e., free of significant defects and chemical modifications such as oxidation. The materials could be functionalized at the edges. These materials are dispersed in solutions rather than in aggregated or insoluble forms as their parent starting materials. Also disclosed is a method comprising the steps of intercalating an insoluble graphitic material. The method may comprise exfoliating graphite and re-intercalating the resultant material with an acid composition, such as oleum, and a strong organic base such as tetrabutylammonium hydroxide in a solvent solution to form a homogenous suspension, which is then agitated to form dispersed graphene materials. The materials may be solubilized with a hydrophilic polymer and can be further manipulated by transfer into different solvents, formation of films, application to optical and electronic devices, and other applications. The materials are solubilized by functional groups mostly at the edges.

摘要： A unitary graphene layer or graphene single crystal containing closely packed and chemically bonded parallel graphene planes having an inter-graphene plane spacing of 0.335 to 0.40 nm and an oxygen content of 0.01% to 10% by weight, which unitary graphene layer or graphene single crystal is obtained from heat-treating a graphene oxide gel at a temperature higher than 100° C., wherein the average mis-orientation angle between two graphene planes is less than 10 degrees, more typically less than 5 degrees. The molecules in the graphene oxide gel, upon drying and heat-treating, are chemically interconnected and integrated into a unitary graphene entity containing no discrete graphite flake or graphene platelet. This graphene monolith exhibits a combination of exceptional thermal conductivity, electrical conductivity, mechanical strength, surface smoothness, surface hardness, and scratch resistance unmatched by any thin-film material of comparable thickness range.

摘要： A method of producing nano-scaled graphene platelets with an average thickness smaller than 30 nm from a layered graphite material. The method comprises (a) forming a carboxylic acid-intercalated graphite compound by an electrochemical reaction; (b) exposing the intercalated graphite compound to a thermal shock to produce exfoliated graphite; and (c) subjecting the exfoliated graphite to a mechanical shearing treatment to produce the nano-scaled graphene platelets. Preferred carboxylic acids are formic acid and acetic acid. The exfoliation step in the instant invention does not involve the evolution of undesirable species, such as NOx and SOx, which are common by-products of exfoliating conventional sulfuric or nitric acid-intercalated graphite compounds. The nano-scaled platelets are candidate reinforcement fillers for polymer nanocomposites. Nano-scaled graphene platelets are much lower-cost alternatives to carbon nano-tubes or carbon nano-fibers.

Such method comprises the following steps: mix a soluble salt of a divalent metal ion M2+, a soluble salt of a trivalent metal ion M′3+, a soluble salt of a chain alkyl anion A− and a carbon source molecule C and dissolve them in deionized and CO2-eliminated water to prepare a mixed salt solution; mix the mixed salt solution with an alkali solution under nitrogen protection and subject them to reaction and crystallization under nitrogen, and filter the suspension obtained thereafter and wash the filter cake with deionized water until the pH of the filtrate is 7 to 7.5, and then dry the filter cake to obtain layered double hydroxides with an intercalated structure; under an inert atmosphere or a reducing atmosphere, calcinate the layered double hydroxides with an intercalated structure to provide a calcinated product; add the calcinated product into a hydrochloric acid solution for ultrasonic treatment, and separate the solution by centrifugation and wash the precipitate obtained by centrifugation with deionized water until the pH of the filtrate is 6.5 to 7 to obtain the graphene.

摘要： A method of producing nano-scaled graphene platelets (NGPs) having an average thickness no greater than 50 nm, typically less than 2 nm, and, in many cases, no greater than 1 nm. The method comprises (a) intercalating a supply of meso-carbon microbeads (MCMBs) to produce intercalated MCMBs; and (b) exfoliating the intercalated MCMBs at a temperature and a pressure for a sufficient period of time to produce the desired NGPs. Optionally, the exfoliated product may be subjected to a mechanical shearing treatment, such as air milling, air jet milling, ball milling, pressurized fluid milling, rotating-blade grinding, or ultrasonicating. The NGPs are excellent reinforcement fillers for a range of matrix materials to produce nanocomposites. Nano-scaled graphene platelets are much lower-cost alternatives to carbon nano-tubes or carbon nano-fibers.
