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.

A material and method are disclosed such that the material can be used to form functional metal pieces by producing an easily sintered layered body of dried metal paste. On a microstructural level, when dried, the metal paste creates a matrix of porous metal scaffold particles with infiltrant metal particles, which are positioned interstitially in the porous scaffold's interstitial voids. For this material to realize mechanical and processing benefits, the infiltrant particles are chosen such that they pack in the porous scaffold piece in a manner which does not significantly degrade the packing of the scaffold particles and so that they can also infiltrate the porous scaffold on heating. The method of using this paste provides a technique with high rate and resolution of metal part production due to a hybrid deposition/removal process.
