NOVELTY - Composition (I) comprises at least one polymer binder, graphene sheets, and graphite, where the ratio by weight of graphite to graphene sheets is 40:60-98:2.    USE - (I) is useful for making articles (claimed) or at least a part of articles, which are fuel system components (such as fuel lines and tubing, fuel tank filler pipes and connectors, fuel line connectors, fuel pumps, fuel pump and delivery module components, fuel injector components, fuel filter housings, fuel line grounding clips, fuel tank flanges, fuel filter clamps, fuel tank caps, and components comprising heat dissipation elements, such as heat sink fins, fuel tanks); automotive components such as electrical and electronic system connectors and housings, body panels and other body components; airplane components; pipes and tubes; seals; gaskets; electrical and electronic switches, connectors and housings; heat sinks; circuit board housings; contacts; antennas; electrodes; battery and ultracapacitor components; sensor components and housings; electronic devices housings (such as for televisions, computer equipment, video game systems, displays and portable electronic devices (such as cellular telephones, global positioning system receivers, music players, computers and game devices)); rubber goods; tires; tanks and bottles (such as gas and liquid tanks, cryotanks and pressure vessels). (I) is useful as coatings for: e.g. the passivation of surfaces e.g. metal surfaces, and exterior surfaces such as bridges and buildings, where the coatings are UV radiation resistant coatings, abrasion resistant coatings and coatings having permeation resistance to liquids; solar cell applications; solar energy capture applications; signage; flat panel displays; and flexible displays; and packaging and/or making labels. (I) is useful in inventory control and anti-counterfeiting applications (such as for pharmaceuticals), including package labels. They may be used to make smart packaging and labels (such as for marketing and advertisement, information gathering, inventory control and information display). (I) is useful: to form a Faraday cage in packaging, such as for electronic components; and in the manufacture of housings, antennas, and other components of portable electronic devices, such as computers, cellular telephones, games, navigation systems, personal digital assistants, music players, games, calculators, radios, artificial "paper" and reading devices. (I) is useful as coating for applying on a substrate to prepare printed electronics e.g. memory chips, batteries, resistors, diodes, capacitors, processors and transistors.    ADVANTAGE - (I) has an electrical conductivity of at least 10-8 (preferably 102) S/cm. The printed films formed by (I) have very good adhesion and rub resistance.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for:    (1) an article printed with (I); and    (2) a method of making a article, comprising printing a coating comprising at least one polymer matrix, graphene sheets, and graphite, where the ratio by weight of graphite to graphene sheets is 40:60-90:10, onto a substrate.
