Development of fibrous materials for shielding of electromagnetic radiation

To analyze the possibility of creating polyacrylonitrile fibrous materials modified with carbon nanomaterials (CNM), the effect of CNM on the process of synthesis of a copolymer of acrylonitrile (AN), methyl acrylate (MA) and 2-acrylamide-2-methylpropane sulfonic acid (AMPS) in dimethylformamide (DMF) was studied. The deterioration of the kinetic characteristics of the process and the molecular mass properties of the obtained copolymer is established. The rheological properties of solutions of poly [AN-co-MA-co-AMPS] in DMF containing CNM were investigated. The effect of CNM on the spinning capacity of AN copolymer spinning solutions, the ability of the spun fibers to plasticization stretching and thermo-orientation one, as well as the physico-mechanical properties of the obtained fibers is shown.
