Abstract

Thermogravimetric analysis of copolymer of acrylonitrile(95%) and methyl acrylate(5%) have been carried out to investigate the activation under $H_2O$(30%) -$N_2$atmosphere at various heating rates. The kinetic equation [$f=1-\exp(-a{\Delta}T)^b$] which was derived on the basis of the nonisothermal activation process of carbon fiber in the $H_2O$(30%)-$N_2$system showed good agreement with experimetal results. The pore volume upon conversion was in good agreement with the model of theoretical pore volume. The pore structures of the activated carbon fiber were influenced by the heating rate, activation temperature and internal-external conversions.
