Experiments with the shield-shaped leaves of the Indian lotus (Nelumbo nucifera) have been particularly effective. Scientists have called this self-cleaning mechanism the lotus effect, a symbol of purity. The nasturtium cleans its leaves using the lotus effect. A scanning electron microscope (ESEM) shows how water droplets move away from the leaf. This is due to the nodular structure of the leaves. The water is repelled at a higher speed, which also washes away dirt and creates a self-cleaning effect.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The lotus effect \u2013 which was extensively studied by botanist Wilhelm Barthlott, with colleagues at the University of Bonn. More than 30 years ago, he noticed that the surfaces of plants, such as the lotus, are always clean. Due to the lotus effect, dust particles cannot adhere to the surface. Water droplets cannot spread out and cannot run over or just touch the dust particles, as is usually the case on smooth surfaces.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The lotus effect has found its place in a variety of different products, ranging from construction to the textile industry and various other fields.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A special chemical process can transform the surface of a fabric into a lotus leaf-like surface. Fabric with a lotus effect is prepared by applying silica beads of various sizes to it, then coating them with a water and oil-repellent polymer finishing film. The transformed surface of the fabric becomes super water and oil-repellent, so it does not get wet with water, nor does it get dirty with mud, tea, or oil.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The Elrus company sells roofing materials that use special materials or glazes for roof tiles that prevent the growth of various lichens and moss and prevent dirt from collecting on roof tiles.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Plant leaves use even more nanotechnology. Their system is often regulated by phorisomes. These are microscopic muscles that open paths in the plant&#039;s capillary system or, if the plant is damaged, close them. Materials with a self-cleaning effect can help save water and chemicals and reduce maintenance costs.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/vsptuj.si\/en\/o-nas\/\">Visit us on social media (Facebook, Instagram)<\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Summarized by<a href=\"https:\/\/asknature.org\/resource\/lotus-leaf-effect\/\"> AskNature.org<\/a> and study materials.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>","protected":false},"excerpt":{"rendered":"<p>Hidrofobnost rastlin je \u017ee bila raziskana, spregledano pa je bilo dejstvo, da se te rastline skorajda ne morejo umazati.
