The present disclosure relates to an improved method for preparing carbon fiber via modified stabilization and carbonization methods during a process of forming filaments of co-polymers comprising acrylonitrile (AN) and vinyl imidazole (VIM) by adding an additive during the during the extrusion process to decrease stabilization temperature, increase crosslinking during oxidation, or decrease the temperatures of carbonization.

Additive for thermal production and reinforcement of carbon fiber, and carbon fiber prepared there from

A quad-polymer composition includes monomers of (a) acrylonitrile, (a) vinylimidazole, (c) methyl acrylate and (d) either acrylic acid or itaconic acid. Such quad-polymer compositions may be used to form fibers (such as by melt spinning) that may then be annealed, stabilized, and/or carbonized to produce carbon fibers. The quad-polymer composition may be used for supercapacitors, lithium battery electrodes once carbonized, and as synthesized, it may be used for wound healing fibers, fabrics, coatings, and films, and anti-bacterial/anti-microbial fibers, fabrics, coatings and films. The carbon fibers formed from the quad-polymer composition may be used for the fiber composites for automobile, aerospace structures, marine structures, military equipment/parts, sporting goods, robotics, furniture, and electronic parts.

Graphene is a single layer carbon-based material known for high strength, high flexibility, high electrical conductivity, high surface area, hydrophobicity and barrier property. Introduction of surface functional groups on graphene enhances most of these properties. A facile and economical process to prepare amine and fluoride functionalized graphenes is disclosed. The disclosed processes utilize direct functionalization of pristine graphene without pre-functionalization (GO). Successful functionalization of both aminated and fluorinated graphenes were confirmed by the analyses of FT-IR, thermal gravimetric analysis (TGA), Raman, UV-Vis, and dispersion study. Amine functional groups can react with epoxy resin and urethane resin to form a covalent bond, and fluorinated graphene can give high hydrophobicity and durability, therefore both can be applied as a material or a component in polymer and composite coatings for corrosion protection, moisture or gas barriers.

Facile direct functionalization of pristine graphene nanoparticles

The invention is directed to melt-processable carbon fiber precursors which have the capability of thermal stabilization in air followed by carbonization in inert atmosphere which make them cost effective and widen their applications.

A fuel composition contains a liquid fuel and a specific amount of nano-sized zinc oxide particles and a surfactant that does not contain sulfur atoms. The nano-sized zinc oxide particles can be used to either improve combustion or increase catalytic chemical oxidation of fuel.

Nano-sized zinc oxide particles for fuel

Systems and methods utilize bicarbonate and acid to form carbon dioxide in a well (e.g., an oil well) to increase pressure in the well to facilitate production of oil and other resources, such as hydrocarbons, from the well. The well can be a closed system that facilitates absorption of the carbon dioxide into the oil resource. After the carbon dioxide is absorbed within the oil, the oil containing the carbon dioxide can be produced by the well. The carbon dioxide can be recycled after the resource is mined from the well to create bicarbonate that subsequently can be used with acid to facilitate the production from the well.

A fuel composition contains a liquid fuel and nano-sized zinc oxide particles. The nano-sized zinc oxide particles can be used to either improve cold start performance of internal combustion engines or lower a flash point temperature of a liquid fuel.

A method of recovering petroleum from dormant oil wells or increasing the production of oil wells. An alkali metal or alkaline earth metal carbonate is introduced into a water layer associated with a subterranean petroleum reservoir and/or an explosive composition is introduced into an oil layer associated with a subterranean petroleum reservoir. COgas is produced by reacting the alkali metal or alkaline earth metal carbonate with an acid and/or by detonating the explosive composition.
