Abstract     [Full Text]
    A simple preparation method on creating superhydrophobic surface using non-aligned carbon nanotubes (CNTs) was demonstrated. Superhydrophobic CNT thin films were prepared by doping a sonicated mixture of CNTs and chloroform onto a glass slide. Water contact angles of the CNT thin films were measured using a contact angle goniometer. The thin films were characterized using laser microscope and scanning electron microscope. Experimental results revealed that the highest average contact angle of 162+-2o was achieved when the films\' thickness was 1.628 µm. The superhydrophobic surface was stable as the contact angle only receded from 162+-2 to 157+-2o after 10 min under normal atmospheric condition.
