1. A process for the functionalization of graphene material, the process comprising:
reacting the graphene material at least partially with at least one silane,
wherein the at least partial reaction is carried out during mixing of the at least one silane with the graphene material, wherein the
amount of silane is 5 to 40% by weight, wherein the sum of the mass fraction of the silane and graphene material is 100% by weight, and
wherein the at least one silane is selected from the group consisting of 3-glycidyloxypropyltriethoxysilane [GLYEO], 3-aminopropyltriethoxysilane [AMEO], glycidyloxypropyltrimethoxysilane [GLYMO], 3-aminopropyltrimethoxysilane [AMMO], and a mixture thereof.
