Abstract
A method for producing a nanocoating reinforced by alumina Al2O3 nanofibers involving synthesizing the alumina Al2O3 nanofibers directly from a melt comprising molten metallic aluminum, the method comprising a controlled liquid phase oxidation of the melt, wherein the synthesized alumina Al2O3 nanofibers have a diameter between 3 and 45 nm and length of more than 100 nm and combining the synthesized alumina Al2O3 nanofibers with a polymer matrix to produce the nanocoating material reinforced by the alumina Al2O3 nanofibers. The nanocoating is then applied onto a surface of a substrate using any known coating technique, such as by means of a roll coater. The alumina Al2O3 nanofibers may be monocrystalline alumina Al2O3 nanofibers. The alumina Al2O3 nanofibers and the molecules of the polymer may be aligned.
