NOVELTY - Treating a carbon allotrope involves: providing a carbon allotrope selected from carbon black, amorphous carbon, glassy carbon, graphite, graphene, and/or fullerenes; and surface treating the carbon allotrope by coupling the carbon allotrope with a polyhedral oligomeric silsesquioxane. USE - For treating a carbon allotrope used as a coating composite for imaging components (claimed) of electrostatographic and electrophotographic devices, bias charge rolls, bias transfer rolls, magnetic roller sleeves, intermediate transfer belts, and transfer belts. ADVANTAGE - The polyhedral oligomeric silsesquioxane (POSS) compound possesses high degree of compatibility in blended polymers and is easily covalently linked into a polymer backbone. The surface treatment of carbon black with POSS into polymers produces carbon black materials with improved properties, such as, improved mechanical strength, thermal and chemical resistance, lower surface energy, and ease of processing and controlling conductivity. The film having a loading level of 2 wt.% POSS surface treated carbon black provides a resistivity of 108 omega /square. The film having the surface treated carbon black has a surface resistivity of 106 to 1013 (preferably 108 to 109) omega /square. The film having the surface treated carbon black has a conductivity profile that is the same as or similar to multi-walled carbon nanotubes. DETAILED DESCRIPTION - Treating a carbon allotrope involves: providing a carbon allotrope selected from carbon black, amorphous carbon, glassy carbon, graphite, graphene, and/or fullerenes; and surface treating the carbon allotrope by coupling the carbon allotrope with a polyhedral oligomeric silsesquioxane, where the polyhedral oligomeric silsesquioxane comprises a compound of formula (I). R1-R8=fluorine-substituted group comprising: (a) linear, branched, saturated, unsaturated, cyclic, acyclic or optionally substituted alkyl groups (hetero atoms are optionally present in the alkyl group); (b) optionally substituted aryl groups (hetero atoms are optionally present in the aryl group); (c) optionally substituted arylalkyl groups (where the alkyl portion of the arylalkyl group can be linear, branched, saturated, unsaturated, cyclic, or acyclic, and hetero atoms are optionally present in either or both of the alkyl portion and the aryl portion of the arylalkyl group); (d) alkylaryl, including optionally substituted alkylaryl groups (where the alkyl portion of the alkylaryl group can be linear, branched, saturated, unsaturated, cyclic, or acyclic, and hetero atoms are optionally present in either or both of the alkyl portion and the aryl portion of the alkylaryl group); (e) linear, branched, cyclic, acyclic or optionally substituted siloxyl groups (hetero atoms optionally present); (f) linear, branched, cyclic, acyclic or optionally substituted silyl groups (hetero atoms optionally present); (g) linear, branched, cyclic, acyclic or optionally substituted silane groups (hetero atoms optionally present); and (h) a functional group selected from hydroxyl, amine, carboxylic acid, epoxide, fluoroalkyl, halide, imide, acrylate, methacrylate, nitrile, sulfonate, thiol, and/or silanol, where at least two R groups are joined together to form a ring. INDEPENDENT CLAIMS are included for the following: (1) a surface treated carbon allotrope comprising: a carbon allotrope selected from carbon black, amorphous carbon, glassy carbon, graphite, graphene, and/or fullerenes, having a polyhedral oligomeric silsesquioxane (I) coupled to the surface of the carbon allotrope; (2) a coating composite for imaging components comprising: a film forming resin; and polyhedral oligomeric silsesquioxane (I) surface treated carbon allotrope uniformly dispersed in the film forming resin; and (3) an imaging component comprising: a substrate; and a coating composite disposed over the substrate, the coating composite comprising polyhedral oligomeric silsesquioxane (I) surface treated carbon allotrope uniformly dispersed in a film forming resin.
