| Popis: | Synthetic carbon was obtained from the porous copolymer of 4, 4'-bis(maleimidodiphenyl)methane and styrene by carbonization in inert and methane atmospheres. The samples were characterized by nitrogen adsorption and mercury intrusion using BET, α s , DR and Kelvin analysis. It was shown that carbonization in an inert atmosphere results in the formation of microporous and mesoporous carbon, while heat treatment in an atmosphere of methane decreases the porosity due to the deposition of pyrolytic carbon in small pores (R < 2–3 nm). |
