In nature, lotus leaves have amazing self-cleaning ability. Whether it is falling dust or splashing water droplets, it is difficult to stay on the surface of lotus leaves for a long time. Behind this magical phenomenon is the result of the unique microstructure of the lotus leaf surface and the nano-level wax crystals. The surface of the lotus leaf is covered with micron-level papillae, and each papilla is covered with nano-level wax crystals. This double rough structure greatly reduces the contact area between the liquid and the lotus leaf surface, making the water droplets on the lotus leaf present a nearly perfect spherical shape, and can also take away dust particles when rolling.
The lotus leaf effect of nano coating is a bionic application of the microstructure of lotus leaves. Through advanced nanotechnology, microstructures similar to lotus leaves are constructed on the surfaces of various materials, thus giving the materials super-hydrophobic properties. When liquid drops on the surface of nano coating with lotus leaf effect, the contact angle is usually greater than 150°, showing a high degree of non-wetting state, just like water droplets rolling on lotus leaves.
This effect has a wide range of value in practical applications. In the field of construction, nano coatings can be applied to exterior walls, glass, etc., which can effectively prevent the adhesion of rain and dust, keep the appearance of the building clean, and reduce cleaning and maintenance costs. In the automotive industry, nano coatings are used on the surface of the car body, which can not only make water droplets slide off quickly, but also prevent stains, so that the vehicle always remains bright and beautiful. In terms of electronic equipment, nano coatings can protect screens, circuit boards, etc., avoid damage caused by liquid erosion, and improve the durability and reliability of equipment.
The lotus leaf effect of nano coatings integrates the wisdom of nature into modern materials science, bringing innovative solutions to many fields. With the continuous development of technology, its application prospects will be broader.
