Bioinspired superhydrophobic coatings of carbon nanotubes and linear π  systems based on the "bottom-up" self-assembly approach

Rough and clean: The physical interaction and self-assembly of oligo(p-phenylenevinylene)s (OPVs) on carbon nanotubes (CNTs) allow the dispersion of the latter in organic solvents. This well-dispersed nanocomposite can be coated on to glass, metal, and mica surfaces to give superhydrophobic self-cleaning surfaces with water contact angles of 165-170° and a sliding angle of less than 2° (see picture)
