▎ 摘　　要

NOVELTY - Polymeric nanoparticle composite comprises dispersion of polymer matrix, and chemically functionalized graphene oxide nanoparticles. USE - The polymeric nanoparticle composite is useful in space and military applications e.g. electrostatic discharge protection, space and aerospace flight, housings for electronics, where a static charge could be problematic, e.g. solar cells or batteries; remove condensation from lenses or be used in in-situ resource utilization to remove volatile components frozen inside Lunar and Martian regolith material. The coating is useful for radar shielding on fighter jets, and airplane wings, propeller or turbine blades. ADVANTAGE - The composite has high mechanical properties, exhibits large voids and increased roughness indicative of rGO aggregation; has high conductivity; has electromagnetic interference shielding and Joule heating properties, which could be used for deicing airplane wings, turbine blades, and propeller blades, since it heats locally, it may also be useful for warming electronic components that are temperature sensitive in military and space; removes condensation from lenses or be used in in-situ resource utilization to remove volatile components frozen inside Lunar and Martian regolith material; enables non-destructive evaluation of components; monitors stress or damage to structural components by examining changes in electrical properties; prolongs use can be difficult to spot relying solely on visual inspection; and can be conceivable in highly sensitive equipment or in manufacturing processes where dust is problematic to clean rooms. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for: (1) preparing (M1) polymeric nanoparticle composite, comprising melting the polymer via heating at 190 degrees C, adding chemically functionalized graphene oxide nanoparticles to molten polymer to form a matrix, pressing the matrix flat, cooling the matrix to room temperature followed by cutting the matrix into small pieces, adding small pieces of matrix into an extruder, stirring and heating the matrix for 2 hours at 180 degrees C using a screw speed of 100 revolutions per minute, removing the matrix from the extruder, placing the matrix into a carver hot press, and pressing the matrix at 180 degrees C for 5 minutes to form films of polymeric nanoparticle composite; (2) a nanoparticle coating, comprising substrates, and chemically functionalized graphene oxide nanoparticle dispersion in a solvent, where the dispersion is deposited onto a substrate; (3) preparing (M2) a nanoparticle coating comprising adding chemically functionalized graphene oxide nanoparticles and a solvent in a vial, stirring chemically functionalized graphene oxide nanoparticles and the solvent to form a uniform dispersion, depositing the dispersion onto a substrate, and allowing to dry to room temperature to form the nanoparticle coating; (4) synthesizing (M3) alkylated reduced graphene oxide nanoparticle, comprising reacting graphite flakes with potassium permanganate and sulfuric acid at 80 degrees C to form graphene oxide (GO), reducing GO with hydrazine hydrate to form a reduced graphene oxide (rGO), and reacting the rGO with a base in N-methyl-2-pyrrolidone (NMP) and an alkyl halide at 60 degrees C to form an alkylated reduced graphene oxide (A-rGO) nanoparticle; and (5) synthesizing (M4) an alkylated reduced graphene oxide nanoparticle, comprising reacting graphite flakes with potassium permanganate and sulfuric acid at 80 degrees C to form GO, reacting the graphene oxide with a base in N-methyl-2-pyrrolidone (NMP) and an alkyl halide at 60 degrees C to form an alkylated graphene oxide (A-GO), and reducing the alkylated graphene oxide with hydrazine hydrate to form an alkylated reduced graphene oxide (A-rGO) nanoparticle.
