I am fabricating an electrode which has platinum deposited on glass. on that organic compound is deposited using electrochemical method. Adhesion of the film on platinum is not good. I have also tried titanium to improve adhesion between glass and platinum. still the film of the organic compound is peeling off.
Any suggestion to improve the adhesion of the film on platinum would be appreciable.
Thank you
How did you deposit your platinum onto the glass? Was it as a mirror from a reduction or some sort of vapour deposition? If so, you have quite a small surface area which is also smooth. If your platinum surface is partially oxidised to 'platinum black' - for example by a method quite similar to the preparation of the traditional 'platinised asbestos' catalysts, you may find that you have a larger surface area which is 'rougher' and this may improve adhesion of your organic compound.
Not exactly. one reason of poor adhesion can be the oxide layer formation on the platinum surface.
