NOVELTY - Fuel system component (I), comprises a polymer composition that comprises at least one polymer and graphene sheets. USE - (I) is useful for providing fuel to a power source, where the power source is an engine or fuel cell (all claimed). (I) is useful in engine compartment of a vehicle and equipment, where the vehicle and equipment include cars, trucks, motorcycles, all-terrain vehicles, lawnmowers, tractors and other farm equipment, construction equipment, marine vehicles (such as power boats and personal watercraft vehicles), snowmobiles, chain saws, garden and landscaping equipment, portable and stationary power generators, aircraft (including helicopters) and fuel-powered toys. ADVANTAGE - The polymeric material has combination of static dissipative properties, fuel permeation resistance, good impact and chemical resistance, and good retention of physical properties at elevated temperatures that can meet the requirements of many fuel system components. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method of providing fuel to a power source, comprising conveying fuel from a storage tank via a path, where the fuel comes into contact with (I) comprising the polymer composition comprising the polymer and functionalized graphene sheets.
