Multi-wall carbon nanotubes (CNT) containing a residual nickel catalyst have been coated with polyaniline (PANI) during the in situ polymerization of aniline with ammonium peroxydisulfate in ethanol (50 vol.%)-water. The Raman spectra demonstrate an incomplete coating of CNT with PANI. The thermogravimetric analysis confirmed the presence of nickel in the resulting composites. The conductivity of composites was of the order of units of S cm ^-1. The permeability spectra indicate the ferromagnetic character of composites.

Mnohostěnné uhlíkové nanotrubky (CNT) obsahující reziduální katalyzátor - nikel byly pokryty polyanilinem (PANI) během in situ polymerace anilinu s peroxydvojsíranem amonným v etanolu (50 vol.%)–voda. Termogravimetrická analýza prokázala přítomnost niklu v kompozitu. Ramanova spektra potvrdila neúplné pokrytí CNT polyanilinem. Vodivost kompozitů dosovala řádově jednotek S ^-1. Spektra permeability potvrdila magnetický charakter kompozitů.
