Actually, i have no idea about the concentration of acids, if i adopt chemical route..
And also no idea about physical route...
Hi Shivani,
Check this article, might help you to functionalize you graphene.

One simple route is to electrochemically oxidise the graphene where by oxygen groups are introduced on graphene surface
Hi...
It may not that much difficult, you can find it from the below article. Acid treatment of 3 : 1 H2SO4 : HNO3
DOI: 10.1039/C0JM04106H
Article: http://pubs.rsc.org/en/content/articlelanding/2011/jm/c0jm04106h#!divAbstract
You may can use surfactants like TX100 or SDS also, but it will affects the properties of graphene.
I have a small doubt about your question?
What do you want to functionalize, is it single layer graphene or single layer graphene film?
I want to functionalize single layer graphene flakes or single layer graphene film both..
