Polyurethane (PU) covers a range of applications in wearable circuits, coating materials, foaming industries, surgical equipments, packing materials and replacement of plastic materials. As per broad applications spectrum, huge data on PU synthesis has been reported so far, with different types of polyols, isocyanates, organic acids, acrylates with different chain extenders, catalysts, emulsifiers and/or PI. In this review, for a comprehensive study of structure‐activity relationship, data from last 5 years has been compiled for photo‐curable PU categorized on the basis of solvent as well as acrylate components. In this review a range of parameters including tensile strength, hardness, flexibility, hydrophobicity/hydrophilicity, solvent resistance, storage/young's modulus, shape recovery, viscosity, curing kinetics and thermal stability has been compared against composition.
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.
