Abstract
Obstacles to the commercialization of carbon nanotubes (CNTs) in alternative energy and clean water applications include high production costs, aggregation problems, and poor water solubility. We report the use of Laponite nanoparticles to improve the aqueous phase fabrication of single-walled CNT (SWCNT) percolating networks. SWCNT/Laponite films were cast at varied Laponite and CNT ink concentrations to optimize polydispersity. Structural and morphological characterization identified isolated aggregates, coalesced aggregates, and interconnected networks. Conductive atomic force microscopy studies confirmed that the nanocomposite films maintained their electrical transport properties after heteromixing. Incorporating Laponite improved CNT aqueous dispersibility, prevented aggregation, and promoted continuous, homogenous film formation.
