Abstract: 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° to <150° and resulted in superhydrophobicity. [ABSTRACT FROM AUTHOR]
