Will dehydrated sugar bind to the surface of graphite?

Hello there.

I plan to coat graphite with carbon from the dehydration of sugar with concentrated sulfuric acid to produce a carbon/carbon composite. My approach would be to first mix powdered graphite in a sucrose solution then dry the mixture to produce sugar-coated graphite. I would then react the sugar-coated graphite with concentrated sulfuric acid to attempt to leave a carbon coating on the surface of each graphite particle.

My worry is this: I am not sure if this method would indeed leave a carbon coating on the graphite (core) surface. I have read that if the composite was pyrolyzed instead, it would definitely leave a carbon coating on the graphite surface.
