Stimulus-Responsive Macromolecules in Polymeric Coatings

Abstract

Continuous interests in stimuli-responsive macromolecules significantly impacted new developments in polymeric coatings. Responsiveness to bacterial attacks, ice or fog formation, anti-fouling properties, autonomous self-cleaning and self-healing, or drug delivery systems, are just a few examples of modern functions of macromolecules and other components utilized in polymeric coatings. These autonomous responses to various external stimuli combined with the suitable protection and appearance are particularly attractive functions. This review outlines recent advances in the development of novel stimulus-responsive polymeric coatings in the context of current and future trends. A combination of stimuli-responsiveness, protection and durability, appearance, and other “smart” functions make polymeric coatings particularly attractive as integral components of future engineered systems. This review consists of four sections, (1) stimulus-responsive protection, (2) stimulus-responsive appearance, (3) smart functions, and (4) future trends and opportunities. The purpose of this monograph is not to list all stimuli and responsiveness utilized in polymeric coatings, but address favorable and unpropitious, in our view, scientific advances and technological opportunities in the development of a new generations of “smart” coatings that still maintain traditional functions of protection and appearance.
