Effect of electrostatic repulsion on the hindered diffusion of nanoparticles. The fiber surface charge density was taken to be −0.05 C/m2, the ionic strength of the solution was set to 0.02M and λ was 0.5. The fiber volume fractions were 0.03 (a) and 0.06 (b). Hindered diffusion is the ratio of the overall diffusion coefficient in the fibrous medium transverse to the fiber direction, D⊥, over the diffusion coefficient in solution, Do.
