The research group "Carbohydrate Chemistry, Polymers and Industrial Additives" by the University of Murcia (UMU), has created a nano-coating built on different surfaces is able to repel a wide range of liquids.
Surfaces treated with this painting (one metric nano-layer composed of siliceous materials and polymers that hold air on its surface) become impervious to liquids such as coffee, wine or oil.
The paintings, which are called "superomnifóbicas" have many possible applications, ranging from objects that do not get dirty, protection stone heritage or taking anti-graffiti surfaces.
"Virtually any liquid take to painting bounces without wetting it, ie, we have dry surfaces even if it rains or protected surfaces from stains other liquids such as oils, alcohols or other organic compounds," says Professor Pedro Antonio García Ruiz, head of the investigation.
The coatings are based on nano particles self-organize when deposited in layers on surfaces, employment, although not new, the University of Murcia has been developed using a system of two layers: one made up of polymers usually employed in paints, and the other composed of silica particles commercially available.
Both compounds of the layers are available in the market at reasonable prices, so you can use this product for many applications that were previously impossible because of the high expense.
The project, funded by the Centre for the Development of Industrial Technology (CDTI), has been developed by the University of Murcia for the company grenadine Rugoplast paintings, which has enabled it to market a range of competitively priced superomnifóbicas paintings.
