Expanded Graphite-Polyurethane Foams for Water–Oil Filtration

ACS Applied Materials & Interfaces, 2019
Herein, 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, 2011
Abstract 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, 2008
Conductive 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.

Synergistic effect of nano magnesium amino-tris-(methylenephosphonate) and expandable graphite on improving flame retardant, mechanical and thermal insulating properties of rigid polyurethane foam

Materials Chemistry and Physics, 2018
A novel nano phosphorus and nitrogen based flame retardant, i.e. magnesium amino-tris-(methylenephosphonate) (Mg-AMP) was synthesized and characterized by Fourier-transform infrared and X-ray diffraction spectroscopies, transmission electronic microscopy,

Preparation of Expanded Graphite Using Recycling Graphite Rods by Microwave Irradiation

Advanced Materials Research, 2012
After 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, 2001
The 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 ...
