HDPE/expanded graphite electrically conducting composite
Composite Interfaces, 2004In this study, HDPE/expanded graphite electrically conducting composites were prepared in the presence of expanded graphite (EG) via a melt-blending process. The microstructure, electrical, mechanical and thermal properties of the resulting HDPE/EG composites were investigated. The experimental results revealed that EG could be dispersed in the form of

Effect of Expanded Graphite Lattice in Exfoliated Graphite Nanofibers on Hydrogen Storage
The Journal of Physical Chemistry B, 2005A graphite exfoliation technique, using intercalation of a concentrated sulfuric/nitric acid mixture followed by a thermal shock, has successfully exfoliated a herringbone graphite nanofiber (GNF). The exfoliated GNF retains the overall nanosized dimensions of the original GNF, with the exfoliation temperature determining the degree of induced defects,

Expanded Graphite-Polyurethane Foams for Water–Oil Filtration
ACS Applied Materials & Interfaces, 2019Herein, expanded graphite is successfully combined with waterborne polyurethane to develop porous foams with underwater oleophobic properties for the separation of surfactant-free, oil-in-water mixtures and emulsions. To obtain foams with different pore sizes and therefore with different performances in the oil-water filtration process, two solvent ...

Nickel/Carbon composite materials based on expanded graphite
New Carbon Materials, 2011Abstract Monolithic nickel/carbon (Ni/C) composites were prepared from coal tar pitch-impregnated compressed expanded graphite pre-decorated with NiO particles (EGNiO) by pyrolysis at 550 °C and subsequent steam activation at 800 °C. The microstructural arrangement of the Ni-comprising nanoparticles in the composites was investigated using ...

Characterization of Expanded Graphite/Flake-Type Graphite Filled Conductive Polymer Composites
Advanced Materials Research, 2008Conductive polymer composites (CPCs) consisting of expanded graphite (EG), flake-type graphite (FG) and thermalsetting resin were fabricated by means of a preform molding technique. Conductive fillers, EG and FG, were mechanically mixed with the phenol resin to provide an electrical property to composites.

Preparation of Expanded Graphite Using Recycling Graphite Rods by Microwave Irradiation
Advanced Materials Research, 2012After washing, milling and calcining, the graphite rods recycled from waste dry batteries were used as raw material to prepare expandable graphite by chemical oxidation (using acetic anhydride as inserting and potassium dichromate as oxidant), the expanded graphite was prepared from the obtained expandable graphite by microwave radiation (MW) at 1000W ...

Sorption Properties of Thermally Expanded Graphite
Chemistry and Technology of Fuels and Oils, 2001The powder was then heat treated at 1150 ‐ 1200 °C by blowing compressed nitrogen through a tubular electric furnace (quartz tube length of 80 cm, diameter of 2 cm) at a rate that ensured residence in the heat-treatment zone for 1.2 ‐ 1.3 sec. Important fluctuations in the temperature in the furnace were prevented by the small amounts of oxidized ...
