The ionic current and electroosmotic flow (EOF) are studied in hydrophobic nanopores numerically. The Poisson, Navier-Stokes, and Nernst-Planck equations were solved simultaneously by finite element method. For the characterization of hydrophobic nanopores, the Navier-slip boundary condition was replaced the no-slip boundary condition on the surface of the nanopore, and a wide range of slip lengths is used in order to cover all the possible hydrophobic conditions. The effect of hydrophobicity on different ionic current mechanisms is investigated. Also, the effects of voltage difference, electrolyte concentration, and radius of nanopore on the ionic current in hydrophobic nanopores are studied. The results show that nanopore hydrophobicity affects the convective and electrophoretic ionic current significantly. Due to the EOF enhancement by increasing the nanopore’s slip length, the convective ionic current signifies, and the electrophoretic ionic current dwindles.
