ChinaParallel, stretched and evenly arranged mesophase pitch based graphitized carbon fibers with diameters of 50-53 lm were coated with different amounts of acrylonitrile butadiene styrene (ABS) resin, and hot-pressed to produce carbon fiber/ABS resin composites. The morphology, optical texture and crystal structure of the carbon fibers and their composites were characterized by scanning electron microscopy, polarized light microscopy and X-ray diffraction. The influence of the graphitization temperature and fiber content on the thermal conductivity of the composites was investigated. The thermal diffusivity and thermal conductivity of the composites along both fiber axial and radial directions showed an obvious difference, owing to the high orientation of the graphite crystals along the axial direction of the carbon fibers.The thermal diffusivity of the composites along the carbon fiber axial direction increased both with the graphitization temperature and fiber content. The composite with 54 vol.% carbon fibers graphitized at 2900°C showed the highest thermal conductivity.A palygorskite/carbon composite was prepared through hydrothermal treatment of palygorskite and cellulose, and its adsorption behavior for methylene blue (MB) was investigated.The effect of adsorption conditions on the capacity and kinetics was also investigated. The adsorption kinetics of MB onto the composite is best described by a pseudo-second-order equation. The adsorption isotherms conform to the Langmuir isothermal adsorption equation. The adsorption thermodynamic parameters calculated from the isotherms indicate that the adsorption of MB on the composite is endothermic.

As-prepared F-graphene as a very high fluorine content (49.7 at%), and an amorphous-like two-dimensional nanostructure. These features facilitate the rapid diffusion of lithium ions during discharging. The F-graphene exhibits better electrochemical performance, especially, a higher specific power density than the F-graphite.

The pore structure of the ACs was characterized by nitrogen adsorption and the electrochemical performance by galvanostatic chargedischarge and cyclic voltammetry. Results show that the ACs' specific surface area, total pore volume, specific capacitance, as well as energy density are maximized using an activation time from 6 to 10 min or KOH/peanut shell mass ratio from 0.6 to 2.0 under otherwise identical conditions. When the KOH/peanut shell mass ratio was 1.0, microwave power was 600 W and activation time was 8 min, the specific surface a...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
