Superhydrophobic PDMS coated 304 stainless-steel mesh for the removal of HDPE microplastics

The use of microplastics is a global issue that affects the environment, the economy and human health. Here we describe a superhydrophobic 304 stainless steel obtained by combining chemical etching and PDMS modification. Among other techniques, field emission scanning electron microscopy (FE-SEM) an...

A surface mechanism promoting the removal or microplastics is also proposed, considering the surface properties of the solid pollutants as well as the wetting properties of the superhydrophobic coating.
