NANOTECNOLOGIA: SIMULAÇÃO DE SUPERFÍCIES HIDROFÓBICAS POR MEIO DE MATERIAIS ALTERNATIVOS

Hydrophobic surfaces have aroused a great deal of interest in various areas because of their importance and potential industrial applications. Hydrophobic molecules are usually nonpolar, so there is no attraction between water molecules that are polar. These materials that do not have a good interaction with the water are already sold worldwide: shirts that do not get dirty, shoes that do not allow the passage of liquids, glasses of cars that facilitate the water slide having a better visualization on rainy days and even in medicine with microdevices that attack exactly the desired location. The wettability of the surface of a material is a property that is also present in everyday life, and is often not easily visualized, being present in several plants, bird feathers and even the wings of some insects. In this way it is considered that Nanotechnology is present in the daily life of the population and it is indispensable that this subject be taken to the classes of Chemistry of high school. According to some studies, it is the responsibility of secondary education to play an essential role in the formation of the citizen through relevant and current topics such as Nanoscience and Nanotechnology, as well as others with a strong relationship with social and environmental aspects. For this reason we present this work, in which we show some materials that can be used to simulate some nanotechnology practices focused on teaching. The research was carried out with professors of the Licentiate course in Chemistry and members of the PDVL experimentation GT. It was possible to observe that the materials actually simulate hydrophobic surfaces and are easily accessible and can be used by teachers as a help tool in the teaching of Chemistry.
