“Photoreactive
Azido-Containing Silica Nanoparticle/Polycation Multilayers: Durable
Superhydrophobic Coating on Cotton Fibers”
Scientists
are reporting development and successful testing of a fabric coating that would
give new meaning to the phrase “stain-resistant” — a coating that would take an
active role in sloughing off grease, dirt, strong acids and other gunk. The
report, which shows that the coating is even more water-repellent than car wax
or Teflon, appears in ACS’ journal Langmuir.
