Progress in preparation,modification and application of phenolic-based activated carbon fibers
Phenolic-based activated carbon fiber is a kind of porous fiber material with high specific surface area and uniform pore size distribution.The preparation method of phenolic-based activated carbon fiber is introduced from the three aspects of preparation,carbonization and activation.The structure of phenolic-based activated carbon fiber,its precursor fiber structure modification,activation process regulation,metal loading and other modification methods are introduced.The application status of phenolic-based activated carbon fiber in adsorption recovery,medical treatment and supercapacitor is introduced,and the development trend of phenolic-based activated carbon fiber is prospected.
