self cleaning

The fragility of biological systems is largely compensated by their ability to self-repair and clean. This section groups EPFL’s research projects that get inspired from this amazing properties to create smart, self-maintained materials with prolonged life span.

A UV nanoimprint lithography (UVNIL) process and hybrid polymer nanocomposites are used to produce self-cleaning surfaces, which replicate the sub-micron textures of natural superhydrophobic surfaces such as rose petals and lotus leaves. Food packaging with such surfaces is useful to avoid wasting foods, and to reuse food ware with no need of cleaning.
