Abstract
Exfoliated graphite (EG) has been modified with pyrolytic carbon produced by 750°C carbonization of poly(vinylidene fluoride) (PVDF), tolylene diisocyanate (TDI), and polyisocyanate (PIC) applied to the EG surface from solutions. The pyrolytic carbon obtained had the form of particles ranging in size from 200 nm to 1 μm. The microstructural characteristics of the carbon-carbon materials depend on the chemical composition of the carbon precursor: S = 15.8 to 63 m2/g; nitrogen sorption from 24.7 to 59.2 cm3/g (−190°C); micropore volume, up to 7.4 mm3/g; benzene vapor absorption from 0.07 to 0.27 g/g (20°C).
