An article of our colleague, Dr. Radhakrishan Jagdheesh, has been recently published in a recognized scientific journal of Surface Engineering.
Dr. Jagdheesh studied self-organised microspiked surface structures that were fabricated with a picosecond laser source on austenite stainless steel. The laser-processed surface structures were subjected to low-temperature annealing for chemical modification to reduce the surface free energy of the metal oxides formed due to laser processing. The multi-scale structures generated with a fluence of 1.3 J/cm2 showed superhydrophobic character with a high contact angle about 158 ± 3° and low contact angle hysteresis <5°.
