Many of the conductive media between electrodes in graphite electrodes are polymer compounds, and the common ones are silanes, tetrafluoroethylenes, carbosilanes or superhydrophobic media. Hydrocarbon based words can be used as a conductive surface.

I have studied this problem, it is like this, 1. The surface of graphite compounds generally has uneven hydrophobicity, and the second is that the conductivity is not good, and the hydrophobicity can overcome the shortcomings of poor conductivity. The common ones are related to polymers: super Hydrophobic silane, hydrophobic carbosilane, superhydrophobic copper, etc., but this is graphite compound, graphene compound, etc. are all composed of graphene. Obviously, the hydrophobicity of graphene is conducive to making conductive materials, so these two components There are ways.  2. Conductive medium, just use it. This is essentially a crystal structure of superhydrophobic material, or a simple composition, such as carbocation crystals. The middle of graphene is hollow, so this hollow structure cannot be used as a conductive medium, so it is commonly used The most important thing is to use superhydrophobic diflucillin potassium calcium salt, which has a simpler composition and better effect, as a conductive medium.

Substances with relatively poor water will crystallize a lot and become a crystal structure with a dense structure, such as a droplet, such as a composite crystal composed of iron.

In fact, carbon dioxide can also be a conductor, which can be a dielectric substance, such as graphite; it can also be a hydrophobic substance, such as water. Both types of substances are suitable for spaced conductive bodies. Carbon dioxide cannot be used as a hydrophobic conductor, because it cannot be used as a conductive medium. In the case of proton conduction and ion conduction, carbon dioxide cannot be used as a conductive medium.

Graphene is chosen because it conducts electricity
