METHOD FOR OXIDATIVE STABILISATION OF POLYACRYLONITRILE FIBRES FILLED WITH CARBON NANOTUBES |
| 摘要 |
FIELD: chemistry.SUBSTANCE: moulded fibres are subjected to heat treatment in an air medium while heating and maintaining a constant length. Content of carbon nanotubes in the fibres is 0.3-0.5%. The surface of the nanotubes contains oxygen in amount of not less than 3.5 at %. Oxidative stabilisation is carried out by raising temperature from 180°C to 230°C at a rate of 0.5°C per minute for 110-130 minutes.EFFECT: simple technique owing to shorter process duration and improved strength properties of polyacrylonitrile fibres owing to low content of carbon nanotubes.1 tbl, 7 ex |
