Not able to coat ball milled graphite samples on ITO for cyclic voltammetry ?

27 May 2025 1 9K Report

I want to spin coat ball milled graphite powders on ITO after sonicating with solvent DMF ,i am not able to coat on ITO glass ,hence it is not uniformly coated on ITO,what should be the reason and please help me with the solution,

thanks in advance

Ensure proper dispersion and adhesion by following these steps:

Disperse graphite in solvent (e.g., ethanol, DMF, or water) with a binder like Nafion or PVDF; ultrasonicate for uniformity.

Clean ITO thoroughly with ethanol, acetone, and DI water, then dry.

Drop-cast or spin-coat the dispersion onto ITO.

Dry at 60–80 °C to fix the film.

If coating still fails, try adjusting graphite concentration, binder ratio, or surface activation (e.g., plasma treatment) of ITO.
