Abstract
A ceramic membrane includes an alumina (AlO) layer; and a polyamide nanocomposite layer at least partially covering a surface of the alumina layer. The polyamide nanocomposite layer contains polyamide-functionalized silicon carbide (SiC) nanoparticles having an average particle size of 0.1 to 1 micrometer (μm), an amine-functionalized SiC moiety, an acyl aryl moiety, and a piperazine moiety. The amine-functionalized SiC moiety contains a SiC core and an amine functionalized silicon dioxide (SiO) shell covering the SiC core. The amine-functionalized SiC moiety is covalently bonded to the piperazine moiety via the acyl aryl moiety; and the amine functionalized SiOshell contains at least one amino group containing structural unit that is covalently bonded to the SiOshell.
