\n The lotus leaf is a typical self-cleaning plant in nature. Water droplets falling on the lotus leaf will form water droplets that roll freely on the surface and take away dust and other dirt. <\/p>\n

\n Through in-depth analysis, it was found that the multi-scale structure of the lotus leaf surface and the existence of epidermal biowax are responsible for the “self-cleaning” of the lotus leaf surface. This property of the lotus leaf is called “superhydrophobicity”. <\/p>\n

\n Even if you pour sewage on the lotus leaves, there will be no stains on the leaves. This kind of “self-cleaning” surface, after people figured out the reason why it “comes out of mud without being stained”, through the applicationDeco Nanotechnology<\/strong>can make it happen. <\/p>\n \n \n \n \n \n \n \n \n Why are the water droplets on some leaves spherical and able to roll around, while others are flat and stay in one place? <\/p>\n \n \n A drop of water is on a solid surface and there are three interfaces in the entire diagram. The red one is the interface between solid and water, the blue one is the interface between solid and air, and the black one is the interface between water and air. The black interface is curved. If we draw a line from the intersection of red, black and blue along the direction of the black surface, it is called the tangent line of the curve at that point. <\/p>\n \n \n \n In the picture, it is the green line. There is an angle between the red line and the green line, which we call the “contact angle”. <\/p>\n \n \n What does it look like if the contact angle is very large? <\/p>\n \n \n \n When the contact angle is large, the water droplets will take on a spherical shape, and the place where the water contacts the leaves (equivalent to the red line in the picture above) is very small.\ufffdIt won’t stay in one place, the whole water drop can roll around. <\/p>\n \n \n What would it look like if the contact angle was small? <\/p>\n \n \n \n This is the shape of water droplets on a typical leaf. It is flat, with a large boundary between the water and the leaf surface (that is, the red line is very long). The contact angle is very small, and the water droplets cannot move freely. Thinking further, what would happen if the contact angle was very small, say zero? That’s right, there’s no blue line anymore, all the solids are taken up by water. <\/p>\n \n \n At present, water-repellent, anti-fouling and self-cleaning multi-functional fabrics developed based on the bionic principle of the lotus leaf effect are more common. Deco Nano provides water-repellent, anti-fouling and other self-cleaning finishing agents. After this kind of fabric is treated with bionic finishing, dirt can easily roll off and be easily washed away by water without contaminating the surface. <\/p>\n \n \n \n \n Note: If you need to reprint, please indicate the source!
