Surface| Zusammenfassung: | Complex dielectric permeability and conductivity of two systems, namely polytetrafluorethylene - intact carbon nanotubes and polytetrafluorethylene — carbon nanotubes dispersed in aqueous media, has been studied in super high-frequency range (9 GHz) and at low frequencies (0,1; 1 and 10 kHz).
Doping of the polymer with the dispersed nanotubes decreases percolation threshold (limit) from 4,5 wt. % to 2,6 wt. % due to uniform distribution of the filler in the polymer. This results to increase of interface interaction polymer - carbon nanotubes that is demonstrated by increase of value of real and imaginary component of complex dielectric permeability. |
