Airships and Graphene Film

  1. Jun 16, 2012 #1
    I recently saw this: http://arstechnica.com/science/2012/01/size-matters-when-things-are-just-right-water-flows-freely/

    and was wondering whether it could be used on an airship to keep helium in the envelope (it often dissipates out).

    Since graphene is just a 2d version of graphite, would it make a difference if I simply covered an envelope with a layer of graphite (say, by drawing over it with a pencil as suggested here http://phys.org/news/2010-12-graphene-pencil-sticky-tape-videos.html )?
