Janus Particles Improve Paints and Coatings

Janus particles are engineered to have two surfaces, each with distinct physical properties. One combination for a Janus particle is to have one side hydrophilic (attracted to water) and the other hydrophobic (water-repellant). Until recently, Janus particles could not be produced in large quantities and their commercial applications were unclear. Researchers have now shown that the nanoparticles could be the key to more environmentally friendly paints and coatings.
