I am prepared a Graphene solution in DMSO with different concentrations. Then I deposit the solution on a simple glass substrate, but the issue is the film is very instable in term of sticking. It is very easy to remove from the glass.
So, what the possible way to improve the adhesive of the graphene solution with glass slides. thanks
Muhammad Sajid DMSO (dimethyl sulfoxide) is a good solvent for graphene, but it may not be ideal for glass adhesion. Consider using other solvents that are compatible with both graphene and glass. Ethanol or isopropanol are commonly used solvents for this purpose.

There are a number of ways to change the interfacial tension. A relatively easy way is to treat the glass surface with a plasma etch before depositing the graphene coating. But this may not be sufficient. You may also use an acid etch first to literally roughen the surface of the glass, the use plasma to ensure it is clean, then deposit graphene.

Use Ethanol, the best solvent to adhere graphene on plate.
