Modification of polyacrylonitrile (PAN) fibers with cobaltous chloride has increased crystal size, crystallinity, and density, and also improved tensile strength and modulus of the resulting carbon fibers. In this study, the effect of cobaltous chloride modification on the physical properties, micro

## Abstract Polyacrylonitrile (PAN) hollow fibers were pretreated with ammonium dibasic phosphate, then further oxidized in air, carbonized in nitrogen, and activated with carbon dioxide. The effects of activation temperature of a precursor fiber on the microstructure, specific surface, poreβsize d
In this work, polyacrylonitrile hollow fiber was oxidized, carbonized, and activated by carbon dioxide into activated hollow carbon fiber. The effects of the activation temperature on the characteristics of the resulting activated hollow carbon fiber, including the mechanical properties, the surface
