“…HEA-terminated WPU showed much lower tensile strength than PETA-terminated WPU. HEA gives much more significant swelling than PETA [121]. This phenomenon is because the methyl group is electron-donating.…”

Waterborne polyurethane coatings prepared by UV-induced photoreactions (UV-WPU) are becoming very attractive due to the increasingly stringent environmental demands. They were developed to replace solventbased polyurethanes in the coatings of wood, paper, plastics, metal, and glass, mainly because of their good physicochemical, rheological, and optical properties. Several UV-WPU formulations have been tested over the years, making their research substantial. However, no valuable review of this literature, focusing on the significant influencing factors in UV-WPU's manufacture, is available to date. This work aims to answer specific questions about the state of these materials' art, such as: "which monomers have been used most in UV-WPU synthesis?", "what type of photo-initiator has promoted the most efficient curing of the material?", "what additives or particles have been tested for composite UV-WPUs?", "which applications have UV-WPUs been directed to?", "what adaptations and technologies have already been tested to overcome the challenges of the process?", among others. As a result of a systematized bibliographic search in four databases, considering the period from January 2000 to July 2020, a total of one hundred and thirty-eight distinct and relevant articles on UV-WPUs were found. From this study, we hope to present a scientific source on the current state-of-the-art of UV-WPU synthesis, providing new combinations of raw materials and intelligent solutions, thus making material and industrial engineers able to mitigate the inconveniences of the process.

“…The IAEE promoted an increase in the cured coatings' tensile strength and pencil hardness, while the elongation decreased. This behavior can be associated with the high reactivity of IAAE, which has two isocyanates and two unsaturated functional groups, providing a high crosslink density [121].…”

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.

“…Relatively new environmentally-friendly PUDs with almost no negative impact on the atmosphere have been developed in the last few years [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ]. One convenient way to eliminate the VOCs in the manufacturing of PUDs in different industrial products, such as coatings, paints, and inks, is by replacing the expensive and harmful organic solvents with cost effective, environmentally benign solvents, such as water [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 ]. The cost effective and environmental-friendly aqueous PUDs are excellent alternatives to their solventborne counterparts and have the potential to greatly reduce environmental pollution compared to using costly and harmful organic solvents.…”

Biodegradable and antimicrobial waterborne polyurethane dispersions (PUDs) and their casted solid films have recently emerged as important alternatives to their solvent-based and non-biodegradable counterparts for various applications due to their versatility, health, and environmental friendliness. The nanoscale morphology of the PUDs, dispersion stability, and the thermomechanical properties of the solid films obtained from the solvent cast process are strongly dependent on several important parameters, such as the preparation method, polyols, diisocyanates, solid content, chain extension, and temperature. The biodegradability, biocompatibility, antimicrobial properties and biomedical applications can be tailored based on the nature of the polyols, polarity, as well as structure and concentration of the internal surfactants (anionic or cationic). This review article provides an important quantitative experimental basis and structure evolution for the development and synthesis of biodegradable waterborne PUDs and their solid films, with prescribed macromolecular properties and new functions, with the aim of understanding the relationships between polymer structure, properties, and performance. The review article will also summarize the important variables that control the thermomechanical properties and biodegradation kinetics, as well as antimicrobial and biocompatibility behaviors of aqueous PUDs and their films, for certain industrial and biomedical applications.
