Superhydrophobic coatings have attracted substantial scientific research in recent years due to their real-world applications in a variety of fields including anti-corrosion, anti-icing, anti-fogging, oil separation and self-cleaning materials. Several approaches and methods have been used in developing superhydrophobic coatings on different substr...

The inherent ability of bio‐inspired underwater superoleophobicity to prevent oil/oily fouling underwater makes it appropriate for a wide range of applications related to environmental remediation, bio‐adhesion, microfluidics, chemical sensing, etc.; however, the co‐association of mechanical durability and optical transparency is essential for real...

Non‐sticking droplets wrapped with fine hydrophobic particles, namely liquid marbles, can be transported both on solid and water pool without an undesired spill of the inner encapsulated liquid. While the stimuli‐responsive release of the inner liquid in the target area is proposed, the time‐programmed release is not yet achieved. Herein, the hydro...

Chemistry and topography are the two distinct available tools for customizing different bio-inspired liquid wettability including superhydrophobicity, superamphiphobicity, underwater superoleophobicity, underwater superoleophilicity, and liquid infused slippery property. In nature, various living species possessing super and special liquid wettabil...

While the development of mechanically durable and abrasion tolerant superhydrophobicity on a rigid substrates itself remains a highly challenging task, the design of superhydrophobic coatings that can restrict both the tensile and compressive deformations of soft and deformable substrates is unprecedented-and such an approach would be of potential...

Controlled tailoring of mechanical property and wettability is important for designing various functional materials. The integration of these characteristics with waste materials is immensely challenging to achieve, however, it can provide sustainable solutions to combat relevant environmental pollutions and other relevant challenges. In this curre...

Marine oil spill cleanup is one of the major challenges in recent years due to its detrimental effect on our ecosystem. Hence, the development of new superhydrophobic oil absorbent materials is in high demand. The third-generation porous materials, namely metal-organic frameworks (MOFs), have drawn great attention due to their fascinating propertie...

The growing emission of CO 2 is a severe cause of concern due to its adverse impact on the environment and climate change worldwide. In the past, various approaches, including synthesis of porous materials and amino modifications, were adopted for efficient and direct separation of CO 2 from flue gas. Recently, hydrophobicity has been introduced to...

In the past two decades, bio-inspired liquid wettability has received widespread attention. Various chemistries and strategies have been proposed for co-optimization of essential features (both topographical and chemical) that confer the extreme and special liquid wettability both in air and under water. However, most of the fabrication processes f...

Bio-inspired and artificial underwater superoleophobic coatings that prevent oil/oily contaminations underwater, have potential for diverse applications. Thus, the synthesis of highly tolerant bio-inspired underwater superoleophobicity is of utmost important for...

In the past, bio‐inspired extreme water repellent property is strategically embedded with commercially available sponges for developing selective oil absorbent. However, most of the reported materials lack physical and chemical durability limiting its applicability at practically harsh settings. Herein, a stable dispersion of polymeric nanocomplexe...

In the recent past, biomimicked super-liquid repellent interfaces were recognized as the prospective and energy efficient so-lution for remediation of such oil-contamination, and mostly two phase oil/water mixtures that are either composed of light oil or heavy oil are demonstrated for gravity driven and environmentally friendly oil/water separatio...

Catalyst-free and readily chemically reactive functional coatings that have immense prospects in various relevant applications, is unprecedentedly synthesized directly using naturally existing bovine serum albumin (BSA), where facile Michael addition reaction between amine and acrylate groups provided simple basis for the covalent integration of de...

The past few decades have witnessed significant development in the field of artificially biomimicked extremely water repellent interfaces, developed mostly through tedious synthetic processes using synthetic/non-biodegradable polymers and fluorinated derivatives rendering health and environmental effects. Only a few approaches furnish superhydropho...

Extended and controlled release of more than single bioactive molecules—simulteneously—from the same biocompatible matrix is challenging to achieve, however important for combating various severe challenges (drug resistance, improved efficacy etc.) related to drug delivery. In the recent past, the meta-stable trapped air (in the lotus leaf inspired...

Aloe vera mucilage (AVM), which mainly consists of an immobilized aqueous phase, is strategically exploited for achieving extremely oil repellent and durable coating. The nature-inspired coating—that derived from AVM and appropreately modified through Micheal addition reaction, is capable of sustaining various challenging chemical (pH 1, pH 12, sur...

In general, the lotus leaf and rose petal-inspired wettabilities are artificially developed through integration of hierarchical topography and essential chemical functionality. However, a fundamental and important aspect of this nature...
