Preparation of aramid-based epoxy resin from low-grade aramid

“…Therefore, it is necessary to modify aramid in preparing functional aramid ber by physical methods such as coating, 16,17 plasma, 18,19 highenergy rays, 20,21 supercritical uid method, 22 or by chemical methods including copolymerization, 23,24 surface etching, 25 or surface graing. [26][27][28][29] A certain amount of aramid ber is labeled as low-grade in the process of polymerization when the molecular weights of the aramid polymers fail to meet the spinning requirements, which was inuenced by various factors such as raw materials, equipment, or operation technologies. It is oen discharged directly as solid wastes owing to its non-utility.…”
