Abstract:

Lotus leaf has a nanostructure with randomly oriented cone-like protrusions (nano-mountains) and nano-valleys between nano-mountains. The nanostructured lotus leave surface possesses an extremely high water-repelling capacity due to super hydrophobic property. This is well-known as “lotus effect”. The “lotus effect” makes nano lotus leaf biomimicked coating suitable for applications in different construction sectors. The present study highlights the possible applications of nano lotus leaf biomimicked coating in various construction sectors, including buildings and infrastructures. The benefits of nano lotus leaf biomimicked coating are emphasized in this paper. More focus is given on the protective role of nano lotus leaf biomimicked coating when applied on different substrates such as concrete, glass, and masonry. In particular, the self-cleansing effect of nano lotus leaf biomimicked coating is focused to reveal its applicability in different construction sectors. In addition, the self-cleansing mechanism of nano lotus leaf biomimicked coating for the protection of substrates is explained with illustrations. This study also includes the different types of substrate, the techniques for the preparation of substrates, and the application methods for installing nano lotus leaf biomimicked coating on various substrates. Above all, some recommendations are given to improve the performance of nano lotus leaf biomimicked coating.
