Water collecting surfaces Made from Polymer Films

What is it about?

In this publication, we report a very simple method to prepare surface coatings that have an unusual textured surface, consisting of raised bumps on a flat background. Our surfaces are made from two different polymers - one water-hating (hydrophobic), the other water-loving (hydrophilic). This surface pattern yields a material that is a highly efficient water collector; moisture in the atmosphere condenses on these surface at a higher rate than flat films.

Why is it important?

The significance of this work is related to the field of localized water collection and sustainability. Atmospheric water collection is a unique alternative to traditional means of water collection and delivery to households and businesses. Our water collection method is spontaneous, and the materials are particularly cheap and simple to prepare.
