▎ 摘　　要

NOVELTY - Producing (P1) an integrated layer of highly oriented halogenated graphene sheets or molecules, comprises e.g.: (a) preparing either a graphene oxide dispersion having graphene oxide sheets dispersed in a fluid medium or a graphene oxide gel having graphene oxide molecules dissolved in a fluid medium, where the graphene oxide sheets or graphene oxide molecules contain 5 wt.% an oxygen; (b) introducing a halogenating agent into the graphene oxide dispersion or gel and effecting a chemical reaction between the halogenating agent and the graphene oxide sheets or molecules to form a dispersion of halogenated graphene sheets or a gel of halogenated graphene molecules, where the halogenated graphene sheets or molecules have a chemical (I); and (c) dispensing and depositing a layer of the halogenated graphene dispersion or gel onto a surface of a supporting substrate under a shear stress condition. USE - The process is useful for producing an integrated layer of highly oriented halogenated graphene sheets or molecules, or graphene and graphene oxide (claimed). ADVANTAGE - The process: is cost-effective; and provides thicker films of graphene-derived materials that exhibit a high dielectric breakdown strength, high dielectric constants, adequate mechanical strength, good thermal stability and good chemical stability. DETAILED DESCRIPTION - Producing (P1) an integrated layer of highly oriented halogenated graphene sheets or molecules, comprises: (a) preparing either a graphene oxide dispersion having graphene oxide sheets dispersed in a fluid medium or a graphene oxide gel having graphene oxide molecules dissolved in a fluid medium, where the graphene oxide sheets or graphene oxide molecules contain 5 wt.% an oxygen; (b) introducing a halogenating agent into the graphene oxide dispersion or gel and effecting a chemical reaction between the halogenating agent and the graphene oxide sheets or molecules to form a dispersion of halogenated graphene sheets or a gel of halogenated graphene molecules, where the halogenated graphene sheets or molecules have a chemical formula of (C6(Z)x(O)y) (I); (c) dispensing and depositing a layer of the halogenated graphene dispersion or gel onto a surface of a supporting substrate under a shear stress condition, where the step of dispensing and depositing procedure include shear-induced thinning of the halogenated graphene dispersion or gel and shear-induced orientation of halogenated graphene sheets or molecules, to form a wet layer of halogenated graphene on the supporting substrate; and (d) removing the fluid medium from the wet layer of halogenated graphene to form the integrated layer of halogenated graphene having an inter-planar spacing (d002) of 0.35-1.2 nm as determined by X-ray diffraction. Z = halo element including F, Cl, Br and/or I; x = 0.01-6; y = 0-5; and x+y = less than or equal to 6. An INDEPENDENT CLAIM is also included for producing (P2) an integrated layer of highly oriented halogenated graphene and graphene oxide, comprising (a1) preparing either a graphene oxide dispersion having graphene oxide sheets dispersed in a fluid medium or a graphene oxide gel having graphene oxide molecules dissolved in a fluid medium, where the graphene oxide sheets or graphene oxide molecules contain 5 wt.% oxygen, (b1) mixing a desired content of halogenated graphene sheets into the graphene oxide suspension or gel to form a mixture suspension, (c1) dispensing and depositing a layer of the mixture suspension onto a surface of a supporting substrate under a shear stress condition, where the dispensing and depositing procedure includes shear-induced thinning of the mixture suspension and shear-induced orientation of halogenated graphene and graphene oxide sheets or molecules, to form a wet layer of halogenated graphene-graphene oxide mixture on the supporting substrate, and (d1) removing the fluid medium from the wet layer to form the integrated layer of halogenated graphene and graphene oxide.
