  • Patent number: 9546286
    Abstract: Disclosed herein are resistive composites comprising at least one resin; at least one carbon black having a surface hydrophobically modified with at least one organic group, the at least one organic group having a molecular weight of the composite of 4000 or less and comprising the formula —X(G)-, wherein X is directly attached to the at least one carbon black and is selected from arylene, heteroarylene, and alkylene, G is a substituent of X, and —X(G)- is nonionic; and wherein the resistive composite has a volume resistivity, Rv, at a relative volume fraction, XCB, of the at least one carbon black in the coating, where Rv is at least 106 ohm-cm; and log Rv has a substantially linear relationship with XCB when XCB is varied from 0.1 to 0.5. Also disclosed are coatings made from such composites, such as coatings for rollers/belts for office automation machines, and methods of making such coatings.
