Over the past few decades, reversible
responsive polymer materials
have received interest conjointly from academia as well as industry
owing to their ability to adapt to the surrounding environment, change
adhesion and wettability of copious species upon extraneous stimulus,
and regulate transportation of molecules and ions. Stimuli-responsive
polymers or macromolecules also exhibit the ability to convert biochemical
and chemical signals into mechanical, thermal, optical, and electrical
signals, and vice versa, for which they are utilized in an array of
applications like “smart” optical systems, drug delivery,
diagnostics, and tissue engineering, in conjunction with coatings,
textiles, biosensors, and microelectromechanical systems.
Extensive exploration on reversible responsive polymeric systems for
a variety of engineering functionalities has been done; however,
no collection of all the information is available as such. This Review
consolidates profuse studies of reversible responsive polymers utilized
in an assorted array of functions, inclusive of sensors, drug delivery,
smart and self-healing coatings, etc.
