In an interview, Dr Uttam Manna, Assistant Professor, Chemistry Department, IIT-Guwahati, with Chemical Today magazine speaks about the potential of self-healing and super-hydrophobic coatings for industrial application.
Potential of self-healing and super-hydrophobic coating.
Superhydrophobic coatings repel water in air and are highly prospective material for several relevant outdoor applications— including anticorrosion, self-clean of deposited dust and dirt, energy efficient and eco-friendly removal of oil-spills etc.
But durability of this biomimetic special wettability is a major concern before any practical applications. Often, synthesized biomimetic interfaces are found to be delicate under practically relevant severe settings—like scratching, creasing, exposures of UV irradiation and complex aqueous medium. The self-healing and three-dimensional superhydrophobic coating is a simple and elegant approach to prolong the lifetime of artificial bio mimicked interfaces, and such material are inherently capable of sustaining various physical and chemical abrasions. This approach has emerged very recently with limited proof of concept demonstrations. Further, progress is essential on this research topic, where such material should be developed following simple and scalable synthetic process. This unique approach might resolve existing durability issue of the synthesized material and would appear as facile and robust avenue for many prospective and smart applications in future.

ReplyDeleteManual Water Meters deals with the measurement of domestic and commercial water consumption, it is our duty to make it easy for you to conserve daily use of water. Quantity of water what you use shows the responsibility you have towards future generation and to society. Manual Water Meters is highly accurate for residential applications. This meter is compatible with LOT and is protected with IP-68.
