Electrical conductivity {sigma}(T) of the paper consisting of multiwalled carbon nanotubes (MWCNTs) is studied in the temperature range 4.2-295 K, and its magnetoresistivity {rho}(B) at various temperatures in magnetic fields up to 9 T is analyzed. The temperature dependence of the paper electrical conductivity {sigma}(T) exhibits two-dimensional quantum corrections to the conductivity below 10 K. The dependences of negative magnetoresistivity {rho}(B) measured at various temperatures are used to estimate the wavefunction phase breakdown length L{sub {phi}} of conduction electrons and to obtain the temperature dependence L{sub {phi}} = constT{sup -p/2}, where p Almost-Equal-To 1/3. Similar dependences of electrical conductivity {sigma}(T), magnetoresistivity {rho}(B), and phase breakdown length L{sub {phi}}(T) are detected for the initial MWCNTs used to prepare the paper.
