Why are graphite particles afraid of water?

The reasons why graphite particles are afraid of water are as follows:

If there are substances attached on the electrode body made of graphite (carbon rod). If there are any substances attached, they cannot be washed away with water. It can only be cleaned by soaking it with other chemical reagents and chemically reacting with the electrode fixtures on the graphite electrode body (carbon rod), without affecting the following electrolysis.

Why can't graphite touch water?

The carbon atoms in graphite are sp2 hybridized. Each carbon atom uses three valence electrons to form a covalent bond with three other carbon atoms. six carbon atoms form a planar regular hexagon, and many regular hexagons are connected to form a spatial lattice structure. These spatial network structures are arranged layer by layer, with acertain amount of space between layers, and each layer still has every carbon atom. an electron that has not formed a bond. This electron moves freely in the space between layers, if under the action of an electric field, it will move in one direction, forming an electric current, and graphite can conduct electricity. >

Diffusion means that when a solute dissolves in a solvent, it needs ionization energy to break free and become free ions. The hydration process is the opposite. The process of forming hydrated molecules/hydrated ions after hydration is a process of reducing the potential energy between particles, and this part of the potential energy is released as heat.

What is not ionized in the solution is non-electrolytic, mainly macromolecular organic matter, such as starch, glucose, etc.

The reason is that interaction between graphite and water Has a wonderful hydrophilic/hydrophobic nature.

Since the C-C bonds in graphite molecules have a certain polarity and the graphite surface can adsorb water molecules, the graphite surface has obvious hydrophilicity.

However, even though the graphite surface is hydrophilic, when it comes into contact with water, the water molecules will exert a large dispersion force on the graphite molecules, resulting in the separation and dispersion of graphite molecules. water, thus affecting the structure and properties of graphite
