I *know* it's far more conductive than plastic in humid Boston weather, since I was using paper strips as conductors when driving the pop-bottle electrostatic motor with a VandeGraaff machine. Brown paper from paper bags worked better than bond. Speaking of pencils, I found that india ink has enough carbon that it behaves as Aquadag. For home-made VandeGraaff machines, one can make the conductive sphere electrode out of papier mache, then paint it with a couple of coats of india ink.
