“…In addition to the possibility of preparing different pure [5], doped [6,7], mixed oxides [8] and hybrids [8,9] at relatively low temperatures, sol-gel also enables in-situ control over the nano-and microstructure of prepared materials during transition from sol to gel [10]. Micro-and nanostructure of surfaces has a critical role in the design of superhydrophobic coatings [11] and solgel has been applied in phase separation based strategies [12,13] to achieve suitable micro-and nanoroughness.…”
