Different bio-inspired liquid wettability are derived through modulation of chemistry and topography—but the chemical modulation process emerged as a superior approach for embedding desired wettability and other relevant physical properties.
Design of robust interface having an efficient water harvesting ability is important for more realistic application. Here, a dual chemically reactive porous polymeric interface is introduced to adopt various bio-inspired...
While the development of mechanically durable and abrasion tolerant superhydrophobicity on a rigid interface itself remains a highly challenging task, the design of superhydrophobic coating that can restrict both the...
In
last few decades, multilayer coatings have achieved enormous
attention owing to their unique ability to tune thickness, topography,
and chemical composition for developing various functional materials.
Such multilayer coatings were mostly and conventionally derived by
following a simple layer-by-layer (LbL) deposition process through
the strategic use of electrostatic interactions, hydrogen bonding,
host–guest interactions, covalent bonding, etc. In the conventional
design of multilayer coatings, the chemical composition and morphology
of coatings are modulated during the process of multilayer constructions.
In such an approach, the postmodulations of the porous multilayers
with different and desired chemistries are challenging to achieve
due to the lack of availability of readily and selectively reactive
moieties. Recently, the design of readily and selectively reactive
multilayer coatings (RMLCs) provided a facile basis for postmodulating
the prepared coating with various desired chemistries. In fact, by
taking advantage of the inherent ability of co-optimizing the topography
and various chemistries in porous RMLCs, different durable bioinspired
liquid wettabilities (i.e., superhydrophobicity, underwater superoleophobicity,
underwater superoleophilicity, slippery property, etc.) were successfully
derived. Such interfaces have enormous potential in various prospective
applications. In this review, we intend to give an overview of the
evolution of LbL multilayer coatings and their synthetic strategies
and discuss the key advantages of porous RMLCs in terms of achieving
and controlling wettability properties. Recent attempts toward various
applications of such multilayer coatings that are strategically embedded
with different desired liquid wettabilities will be emphasized.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
