n this experiment you will analyse some innovative materials that are highly water repellent, stainless and require less cleaning thanks to their surface nano-engineering. Those materials have been developed using nature as an inspiration, since some plant leaves have exceptional properties due to their surface composition. The property you will analyse is the superhydrophobic effect found in some leaves, such as the lotus leaf. The effect is due to interplay of surface chemistry and surface topography at the micro- and nano-level. Download the documents below to carry out the experiment and watch the information videos available below. Translations to several languages are also availabe in the NANOYOU website.
