Abstract: A method for producing a submicron-/nano-jute carbon/epoxy composite anti-corrosion coating is described. The method includes heating a jute stick, grinding the jute stick to form a first powder; pyrolyzing the first powder to form a pyrolyzed carbon; grinding the pyrolyzed carbon to form a second powder; ball milling the second powder under the wet conditions to form a submicron-/nano-jutecarbon; mixing the submicron-/nano-jutecarbon, and an epoxy resin to form a first mixture; mixing a hardener with the first mixture to form a second mixture, and coating the second mixture on a mild steel substrate and curing to form the submicron-/nano-jutecarbon/epoxy composite anti-corrosion coating.

Abstract: An anticorrosive nanocomposite is described. The anticorrosive nanocomposite includes a cured epoxy and jute carbon. The jute carbon is in the form of flakes. The flakes have a particle size of 0.05-15 micrometers (?m). Particles of the jute carbon are dispersed in the cured epoxy. A method of preparing the jute carbon is also described.

Abstract: A method of producing submicron carbon particles from oil ash. The method comprises pyrolyzing the oil ash to produce a pyrolyzed oil ash and milling the pyrolyzed oil ash to produce carbon particles having a mean particle size in the submicron regime. The method produces submicron carbon particles which have a very high carbon content (90 to 99 atom %) and a very low content of oxygen, the particles having a ratio of carbon to oxygen ratio of 10:1 to 99:1. The size of the particles may be controlled by the duration of the milling. The submicron carbon particles are devoid of functionalities containing carbon-oxygen double bonds as measured by Raman spectroscopy and X-ray photoelectron spectroscopy (XPS).
