Electroactive polyamide/alumina nanocomposite of various compositions has been been synthesized by in situ oxidative coupling polymerization followed by thermal imidization. X-ray diffraction confirmed pattern of all nanocomposite shows peak corresponding to both alpha-alumina and polyamide. Fourier Transform Infrared and x-ray photoelectron spectroscopy were indicated the presence of amide group and alumina nanoparticles in the nanocomposites respectively. Field emission scanning electron microscope and Transmission electron microscopy showed continuous phase of EPA with Al2O3 particles of 8–18 nm size in the composite. The average roughness values amongst the nanocomposite coating indicated no significant variation. The water contact angle of pure electroactive polyamide and nanocomposite coating showed hydrophilic and hydrophobic property respectively and the slightly hydrophobic nanocomposite coatings posses a superior corrosion resistance than the electroactive polyamide coated and bare 201 stainless steel.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
