Fluorine free superhydrophobic surface textured silica particles and its dynamics-Transition from impalement to impingement

摘要

We report a facile method towards synthesis of fluorine free superhydrophobic mesoporous silica particles. Silica particles were prepared from rice husk (RH) as the silica source and CTAB as the structure directing agent. The as-prepared hydrophilic silica particles were converted to superhydrophobic structures by silane treatments. Silane treatment enhanced the wetting nature of the silica material from 60 degrees to <150 degrees and resulted in superhydrophobicity. (C) 2017 Elsevier B.V. All rights reserved.
