Research into the microstructure, electric and dielectric properties of the systems based on polyethylene glycol and multiwalled carbon nanotubes (MWCNTs), which were functionalized by different methods is done using the methods of impedance spectroscopy and optical microscopy. It is determined that the probed systems show the percolation behavior. It is discovered that when using of OH-functionalized MWCNTs, the percolation threshold of conductivity is increased from 0.44\0 0.55\%, and using H$_2$O-functionalized MWCNTs, the percolation threshold of conductivity is increased to 3\%. It is determined that the percolation threshold of dielectric permittivity considerably increases when functionalized MWCNTs are used.
