FIELD: chemistry.SUBSTANCE: invention relates to chemical technology of polymer materials and deals with method of obtaining aramid threads, modified with carbon nanotubes. Method includes obtaining modifying solution, which contains carbon nanotubes, introduction of modifying solution into polymer solution and/or in the process of obtaining polymer, and/or before thermal processing, and/or before hot-stretching, and/or with further realisation of thermal processing and/or hot-stretching of aramid threads. As modifying solution used is solution, containing preliminarily synthesised single-wall and/or multi-wall carbon nanotubes. nanotubes are functionalised with hydroxyl, and/or carboxyl, and/or hypochlorite groups and/or chlorine ion in amide solvent or in water with specified concentration.EFFECT: invention provides increase of physical and mechanical and exploitation properties of material.7 cl, 1 dwg, 1 tbl, 18 ex |
