In general, PAN and pitch precursors, have been widely used in activated carbon fiber(ACF) manufacturing, but they have an disadvantages of high price. Therefore, polyethylene was adopted as a precursor material to produce activated carbon fiber for low cost and high performance fine dust removal filter. Polyethylene fibers are spun, crosslinked through sulfuric acid treatment and energy radiation. Activated carbon fibers having micropores were prepared by carbonizing crosslinked fibers and then physical and chemical activation. The porosity, specific surface area, and average pore diameter of the prepared ACF were measured. Finally, and the optimization conditions were established through analysis of thermal properties and physical properties.
