We have investigated temperature σ(T) and magnetic field σ(B) dependences of the conductivity σ of multiwalled carbon nanotubes (MWNTs) with different average outer diameter equation image. From the experimental data we have separated the quantum corrections to σ(T) and σ(B). We have discovered that only quantum corrections for interaction electrons (QCIE) to σ(B) take place. It is associated to the absence of the bulk formations of amorphous carbon in produced MWNTs. From the data of QCIE we have estimated the constant of electron–electron interaction λ which is negative (attraction between electrons) and gradually falling with decrease in MWNTs equation image. Influence of defectiveness and structure of MWNTs on electrophysical properties is discussed.
