한국어 초록
Propellant waste was impregnated on the surface of activated carbon fiber and heat-treated at different temperature tointroduce newly developed functional groups on the ACF surface. Functional groups of nitrogen and oxygen such as pyridine,
pyridone, pyrrol, lacton and carboxyl were newly introduced on the surface of modified activated carbon fiber. The porosity,
specific surface area, and morphology of those modified ACFs were changed as increasing the heat-treated temperature from
200 to 500oC. The optimum heat-treatment temperature was suggested to 500oC, because lower temperature given rise to the
decrease of specific surface area and higher temperature resulted in the decrease of weight loss. Propellant waste can be used
as an useful surface modifier to porous carbons.
