A poly(acrylic acid)-carbon nanotube (PAA-CNT) was successfully prepared. The fabrication of selfassembly films from diazoresin and PAA-CNTs was confirmed with UV-Vis spectrometry. Thickness of the films was regularly increased by a layer-by-layer self-assembly process. Furthermore, the ionic bonds in the polymer films converted to covalent bonds under UV irradiation, with the decomposition of diazoresin group. Finally, the surface morphology of the films was investigated by atomic force microscopy. The films are rather flat and uniform through the self-assembly technique.
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.
