Research results on the synthesis of carbon nanotube arrays using a combined catalyst are pre sented. Thanks to optimal synthesis parameters such as temperature, the reagent flow rate, the concentration and type of organometallic compound, and the composition of the catalyst film, a new synthesis method for the arrays of carbon nanotubes (CNTs) of a given topology is developed. The influence of the size effects of topological elements on the characteristics of the CNT arrays is studied. The results of a statistical analysis and research into the CNT morphology by transmission and scanning electron microscopy are shown.
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.
