Uniting Superhydrophobic, Superoleophobic and Lubricating Fluid Infused Slippery Behavior on Copper Oxide Nano-structured Substrates
Sanjeev Kumar Ujjain, Pritam Kumar Roy, Sumana Kumar +2
Copper oxide nanostructures with spherical (0D), needle (1D) and hierarchical cauliflower (3D) morphologies are used to demonstrate superhydrophobic, superoleophobic and slippery b…
Mechanically Tunable Slippery Behavior on Soft Poly(dimethylsiloxane) (PDMS) Based Anisotropic Wrinkles Infused with Lubricating Fluid
Pritam Kumar Roy, Reeta Pant, Arun Kumar Nagarajan +1
We demonstrate a novel technique to fabricate mechanically tunable slippery surfaces using one dimensional (anisotropic) elastic wrinkles. Such wrinkles show tunable topography (am…
Reversible Transition between Superoleophobic and Superoleophilic States on Titania Coated Substrates by UV Irradiation
Jitesh Barman, Sumit Kumar Majumder, Krishnacharya Khare
We demonstrate that tunable superoleophobic surfaces fabricated by a simple spin and spray coating methods of titania on silicon (Si) wafers and stainless steel (SS) mesh, which po…
Electrowetting on dielectrics on lubricating fluid based slippery surfaces with negligible hysteresis
Jitesh Barman, Arun Kumar Nagarajan, Krishnacharya Khare
Low voltage electrowetting on dielectrics on substrates with thin layer of lubricating fluid to reduce contact angle hysteresis is reported here. On smooth and homogeneous solid su…
