“…Today, the nano-based coatings not only serve as protection layers against mechanical aggressors or decorative purposes, but also act as smart materials that are multifunctional. According to the literature, smart coatings can be applied for anti-corrosion, 1, 2 anti-wearing, 3 anti-bacterial, [4][5][6][7] anti-fungal, 8,9 self-cleaning, 10,11 superhydrophobic, 12,13 solar reflective, 14,15 photocatalytic, [16][17][18][19] and radar absorbing 20 and electrically conducting polymeric 21 applications. For example, lotus leaf 22 with naturally attained superhydrophobic and self-cleaning effects has garnered great interest among the researchers due to its potential biomimicking in coatings for self-cleaning, 23 anti-icing, 12,24 anti-fog, 12,25,26 anti-wetting, 27 and anti-fouling.…”
