Electrodeposition of Carbon Nanotubes Triggered by Cathodic and Anodic Reactions of Dispersants

The combination of advanced functionalization methods for surface modification and dispersion of carbon nanotubes (CNTs) and electrochemically triggered strategies for coagulation and film formation allowed efficient electrodeposition of CNTs by cathodic and anodic methods. The electrochemical methods involved the application of cationic basic fuchsin or anionic fluorescein dyes. The dyes adsorbed on CNTs provided electrosteric dispersion. The film forming and binding properties of the dyes and their charge neutralization in electrode reactions promoted deposit formation. The proposed methods allowed controlled electrodeposition of CNT films.
