Researchers at the MNT Lab have developed an innovative way to deposit drops of oil/water on low-energy surfaces (superhydrophobic/superoleophobic), which creates a paradigm shift in terms of understanding “under-water” wetting behavior of large number of substrates.
This new technique is non-intrusive and substrate independent, which makes it very attractive method for the scientific community. This technique addresses the limitations of the conventional drop deposition method. We achieve this non-intrusive, substrate-independent drop deposition method by depositing the drop from this liquid–fluid interface, by using the (un)favorable spreading behavior of the drop at this interface. Massive upsurge in use of low-energy under-liquid surfaces, requiring a correct estimation of the corresponding surface energy, makes our proposed technique extremely important and technologically significant. This has appeared as a cover article in Soft Mater, a journal from Royal Society of Chemistry.
