“…The dispersion stability and particle size, in addition to the product's final properties, will be influenced by the ionic group's content, rigid/flexible segments molar ratio, structure of the monomers, neutralization degree, acrylate double bond percentage, curing conditions, photoinitiator amount, and others. Moreover, the reaction parameters, such as temperature, stirring, component's feeding rate, and order of addition, significantly affect the aqueous dispersion properties [3,34]. Monitoring the nanoparticle morphology produced in the synthesis is essential to control the interconnected network resulting from its aggregation, which will directly affect the quality of the PU film formed [10].…”

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.

“…Polymeric materials have a prominent place in biomedical applications, due to their broad range of physico-chemical properties that can be tailored to fit a wide plethora of applications [1][2][3]. Segmented polyurethanes (PUs) are among the most important classes of biomedical polymers, mainly due to their excellent hemocompatibility and unique mechanical properties deriving from the presence of hard segment-rich and soft segment-rich domains in a phase-separated microstructure.…”

Despite advances in material sciences and clinical procedures for surgical hygiene, medical device implantation still exposes patients to the risk of developing local or systemic infections. The development of efficacious antimicrobial/antifouling materials may help with addressing such an issue. In this framework, polyethylene glycol (PEG)-grafted segmented polyurethanes were synthesized, physico-chemically characterized, and evaluated with respect to their bacterial fouling-resistance properties. PEG grafting significantly altered the polymer bulk and surface properties. Specifically, the PEG-grafted polyurethanes possessed a more pronounced hard/soft phase segregated microstructure, which contributed to improving the mechanical resistance of the polymers. The better flexibility of the soft phase in the PEG-functionalized polyurethanes compared to the pristine polyurethane (PU) was presumably also responsible for the higher ability of the polymer to uptake water. Additionally, dynamic contact angle measurements evidenced phenomena of surface reorganization of the PEG-functionalized polyurethanes, presumably involving the exposition of the polar PEG chains towards water. As a consequence, Staphylococcus epidermidis initial adhesion onto the surface of the PEG-functionalized PU was essentially inhibited. That was not true for the pristine PU. Biofilm formation was also strongly reduced.

“…In biomedicals, G-WBEC can be readily employed in pharmaceuticals in development of nanobots for on-target drug delivery and tumour therapy [274]. There is also the prospect of applying G-WBEC for tissue regenerations, for stronger and high throughput healing and repairs [275], as well as possibility for neurovascular regeneration, as recently demonstrated by Lee et al [276] using graphene/wPU composite.…”
