| (a) Coulomb potentials for surface charges of 0 e (systems (i) and (ii); black line) and −3 e (systems (iii), (iv), (v); red line). The potentials on both ends of the CNT are set to be zero. (b) Average dipole orientation distributions of water molecules along the tube axis. θ is the angle between the dipole orientation and z axis shown in insert. The average dipole orientations remain constant at about 900 in the tube without surface charge, while it fluctuates along z axis for surface-charged CNTs. |
