>I prefer Graphene based product. Better conductivity.

According to the vendor, Mad scientist audio: "it is barely conductive"

According to Chemtronics their silver conductive grease: Maximum electrical conductivity and thermal conductivity

I am pretty sure any contact enhancer must (rpt must) be conductive. You know, otherwise it's a short. No wonder he's mad.

  "I am pretty sure any contact enhancer must (rpt must) be conductive. You know, otherwise it's a short."
  
  If the contact enhancer is conductive then it's a "short". The enhancer is between the two pieces of metal that you want shorted together (a good connection). If the contact enhancer is not conductive then it's an insulator. If you have an insulator between your two metal conductors then you have an "open", not a "short".
  
  Please tell us that you just mis-spoke and that you do understand the difference between a short and a open.

    Graphene has one prominent characteristic - it's highly conductive.

      I thought the superior conductivity of graphene depends upon its being in a monolayer (a layer with thickness of one molecule). Just smeared on to a conductive surface, does it behave as well in conductivity?

        I'm not sure the word smearing is correct. It's applied in the very thinnest layer possible. Not perfect but what is these days? Lol

        I was just wondering, because getting graphene to coat a surface as a true monomolecular layer is the subject of many scientific papers. If not in monomolecular layer, there are data to say it is not as good a conductor as copper.

        I'm betting you don't have a link to any of those scientific papers.

        The fantastic review that Tre' referenced below is far superior to the 2-3 individual papers I found, but if you still insist, I will re-research the topic and post some references. But meantime, read the long review that Tre' referenced. I learned a lot from reading it myself. I am assuming from the get-go that you don't doubt the principle that graphene by definition is a monomolecular film (or a 2D structure as described in the review), composed of a lattice containing repeating units of six carbon atoms in a hexagonal arrangement. If you don't have that, you have graphite, not graphene. This is why I have always been dubious of audiophile contact enhancers that claim to work because of graphene content. I don't see how you can get a 2D film from a coated Q-tip or squeezing a tube. One of the papers I found described a method of coating silicon with graphene by heating to 1000 degrees; this was regarded as a possible breakthrough in solid state electronics.

        Very thin layers, not slobbered on with a Q tip or paint brush. Squeezing it out of a tube? Huh? Where do you guys come up with this stuff? I apply Graphene CE as an extremely thin layer, so thin you can barely see it.
        Some you skeptics might consider adding to your arsenal of complaints - none of these Graphene CE contain two-dimensional Graphene, the Graphene is in solution as a powder.

        "none of these Graphene CE contain two-dimensional Graphene"
        
        I believe, from what I have read, that only the two-dimensional Graphene is low resistance.

        "In solution as a powder" is an oxymoron.

        Random gibberish. I have many years' experience with Graphene, how much do you have? I'm guessing none.
