Patent ID: 8648217

Claim:
A process for the modification of a carbonaceous material (C), said carbonaceous material consisting essentially of carbon, said process comprising: contacting said material (C) with a (per)fluoropolyether peroxide comprising at least one peroxidic moiety comprised between sp 3 carbon atoms and at least one fluoropolyoxyalkene chain (chain R f ); and heating said material (C) while in contact with said peroxide (P) at a temperature exceeding decomposition temperature of said peroxide (P), wherein the material (C) is selected from the group consisting of carbon black, carbon fibers, diamond-like carbon (DLC), graphite, and fullerenes, wherein the peroxide (P) complies with formula (III) here below: A-O—(CF 2 O) a1 (CF 2 CF 2 O) a2 (O) a3 -A′ formula (III) wherein: A and A′, equal or different from each other and at each occurrence are independently selected from the group consisting of —CF 3 , —CF 2 —CF 3 , —CF 2 Cl, —CF 2 CF 2 Cl, and —CF 2 —COF; a1, a2 and a3 are integers >0 such that the number average molecular weight is between 400 and 150,000, with the ratio a2/a1 being comprised between 0.1 and 10 and the ratio a3/(a1+a2+1) is comprised between 0.01 and 0.5.
