The porous aligned carbon nanotube(ACNTs) films prepared by pyrolysis of metal phthalocyanines show an ultrahydrophobic property. The contact angle for water of the films is 161°. The films modified with fluoroalkylsilane show a better hydrophobic property. The contact angle for water of the modified films is as high as 172°. The alignment structure of the films and large fraction of air on the films are considered to be responsible for the ultrahydrophobic property.
