METHOD OF OBTAINING COMPOSITIONS BASED ON CARBON NANOTUBES AND POLYOLEFINS Russian patent published in 2013 - IPC B82B3/00 C08J3/205 C08J7/04 C08L23/00 C08K3/04 

FIELD: chemistry.

SUBSTANCE: invention relates to method of obtaining nanocomposites based on polyolefins, used in obtaining different products, such as films, sheets, tubes, threads and fibres. Carbon nanotubes are preliminarily ground in water with addition of water-soluble polymer with concentration 0.01-0.1 wt %. After that, suspension is dispersed by ultrasound at maximal medium temperature not higher than 70° C. After that, suspension is applied on the surface of polyolefic granules and dried. Obtained granules of nanocomposite contain to 0.5 wt % of carbon tubes.

EFFECT: nanocomposite materials possess high volumetric and superficial electroconductivity, heat-conductivity and high rigidity, with simultaneous increase of tensile modulus of elasticity to 50%, and limit of tensile strength to 30%.
