Facile method to prepare stable superhydrophobic Co3O4 surface
2009
Abstract A facile and novel method was developed to fabricate rough Co 3 O 4 surface with hierarchical micro- and nanostructures by the combination of simple solid state reactions and coating process. After modification with stearic acid, a superhydrophobic surface with water contact angle of 155 ± 1.8° and sliding angle of 2° was obtained. The superhydrophobic Co 3 O 4 surface remained superhydrophobic property in a wide pH range from 3 to 14. The superhydrophobic Co 3 O 4 surface also showed excellent self-cleaning property and high stability in ambient environments.
