Indian Space Research (ISRO) at its Vikram Sarabhai Space Centre (VSSC) has developed superhydrophobic—or water repellant—coatings. These are prepared from a combination of polymers and nanoparticles. T
coatings possess high water contact angle (around 160 °) with excellent water roll-off properties. The coatings can be applied by spraying over different substrates to form good water repellent coatings.
Salient features • High water contact angle • Extreme water repellency • Excellent water roll-off properties • Sprayable (wide area application) • Economically viable application(s) It can find myriad applications in preventing moisture induced corrosion in metals, water repellent coatings in and dishes, moisture barrier for polymers/ composite structures and to roll-off condensed water from metallic structures.
