摘要

Three activated carbons having different surface areas,coconut-shell based (AC-C),pelletized (AC-P)and bamboo-derived (AC-B),were modified by mixing them with four thermoplastic precursors,poly(vinyl alcohol)(PVA),hydroxy propyl cellulose (HPC),citric acid (CiA),and fluorine-containing polyimide (FPI)followed by heat treatment at 900 deg C for 1 h.The porous structures of the modified activated carbons were characterized by nitrogen adsorption and SEM.It was found that the thermoplastic precursors modified the porous structure of AC-B more significantly compared with the other two,AC-P and AC-C.
