On the estimation of the diffuse double layer of carbon nanotubes using classical theory: Curvature effects on the Gouy-Chapman limit

Abstract:

The Poisson-Boltzmann equation is solved numerically in cylindrical space to examine the effects of curvature upon the properties of the diffuse double layer at a charged nanotube in electrolytic solution. Simulations reveal increased double layer capacitance, especially for cylinders with radius less than 20 nm. The potential drop from the nanotube surface to the maximum tunnelling distance is therefore expected to be greater than for larger cylinders, providing a possibly enhanced electroch...
