Volumetric content of graphene nanoplatelets in RTV/GNP composite corresponding to the onset of conductivity: $v_{EX}$ = critical fraction observed during experiment, $v_{CP}$ = percolation threshold according to classical percolation equation [28], $v_{EV}$ = percolation threshold range in excluded volume approach [30], $v_{MF}$ = percolation threshold derived from mean field theory [31].
