Dielectric properties of water in carbon nanotubes — •Philip Loche, Alexander Schlaich, and Roland R. Netz — Freie Universität Berlin, Fachbereich Physik, Arnimallee 14 14195 Berlin

Dielectric properties of confined fluids are important for understanding elementary processes in nanofluids and nanochemistry. Especially cylindrical geometries are of great interest because their applications cover transport through membrane proteins, desalination via nanopores, or transport processes in carbon nanotubes (CNT).

We use Molecular Dynamics Simulations to investigate the dielectric properties of SPC/E water confined in CNTs as model for cylindrical cavities. Comparing various radii and lengths, our results show a high anistropy. Additionally, we perform a finite size scaling of the influence of the nanotube length and compare to the expectation of simple arguments of statistical mechanics.
