The invention pertains to a process for the modification of a carbonaceous material [material (C)], said process comprising: - contacting the material (C) with a (per)fluoropolyether peroxide comprising at least one peroxidic moiety comprised between sp3 carbon atoms and at least one fluoropolyoxyalkene chain (chain Rf), i.e. a fluorocarbon segment comprising ether linkages in main chain [peroxide (P)]; - heating the material (C) while in contact with the peroxide (P) at a temperature exceeding decomposition temperature of said peroxide (P). Still an object of the invention is a modified carbonaceous material having chemically bound on its surface at least one fluoropolyoxyalkylene chain (chain Rf).

Abstract
The invention pertains to a process for the modification of a carbonaceous material [material (C)], said process comprising: - contacting the material (C) with a (per)fluoropolyether peroxide comprising at least one peroxidic moiety comprised between sp3 carbon atoms and at least one fluoropolyoxyalkene chain (chain Rf), i.e. a fluorocarbon segment comprising ether linkages in main chain [peroxide (P)]; - heating the material (C) while in contact with the peroxide (P) at a temperature exceeding decomposition temperature of said peroxide (P). Still an object of the invention is a modified carbonaceous material having chemically bound on its surface at least one fluoropolyoxyalkylene chain (chain Rf).| File | Dimensione | Formato | |
