Review on Technological Significance of Photoactive, Electroactive, pH-sensitive, Water-active, and Thermoresponsive Polyurethane Materials

ABSTRACT

This feature article presents a state-of-the-art review on versatile shape memory polymer, i.e., polyurethane. It forms an important class of shape memory polymers. Several successful stimuli-responsive effects have been achieved in polyurethane such as electroactive, water-active, pH-sensitive, thermoresponsive, and photoactive effect. Various categories of stimuli-responsive polyurethanes are discussed here. Due to characteristic attributes, such as light weight, low cost, high strength, heat stability, fine shape deformability, and shape memory, polyurethane have found application in aerospace, textile industry, sensors, drug delivery systems, and other biomedical relevance. Future advancement is still needed in this field due to structural and industrial preferences.
