METHOD OF OBTAINING THERMOSTABLE NANOCOMPOSITE Cu/POLYAKRYLONITRILE Russian patent published in 2008 - IPC C08L33/20 C08K3/08 C08K3/00 B82B3/00 

FIELD: chemistry.

SUBSTANCE: invention concerns nanotechnology of thermostable nanocomposite Cu/polyakrylonitrile (PAN) production. The claimed method of obtaining thermostable nanocomposite Cu/PAN involves preparation of a mix of CuCl₂, HNO₃ (C_HNO3=37%) and PAN (M_η=1×10⁵), maturing the mix till dissolution of CuCl₂ and PAN in HNO₃, evaporation of HNO₃, heating of the obtained solid substance, so that the ratio of CuCl₂, HNO₃ and PAN in the mix is (1÷6):(15÷600):(1.6÷15) (weight parts) if maturing for 72 hours at 25°C till complete dissolution of CuCl₂ and PAN in HNO₃; evaporation of HNO₃ at 90°C; thermal treatment of the obtained solid substance at the pressure of 10^-3÷760 mm of mercury and temperature of 200÷300°C for 1÷40 minutes to obtain thermostable nanocomposite Cu/PAN containing Cu nanoparticles of the size of 10 to 80 nm.

EFFECT: obtaining of thermostable nanocomposite Cu/PAN by annealing of CuCl₂/PAN mixes containing Cu nanoparticles of the size of 10 to 80 nm.
