“…Vegetable oil is being used to replace petroleum products in the preparation of UV-WPUs, mainly due to its low cost and renewable feedstock [25]. UV-WPUs prepared from castor [13,104,[134][135][136][137], linseed [138], epoxy soybean oil [105], and cardanol [139] polyols showed excellent flexibility, water resistance, hydrolytic stability, shock absorption, and electrical insulation properties. However, the main drawback is their low thermal decomposition temperature.…”

“…Simultaneously, high crosslinking density can prohibit the water molecular penetrating the inside of films and keep hydrophilic groups from moving towards the surface [141]. Reactive diluents as tripropyleneglycol diacrylate (TPGDA) [124,136], trimethylolpropane triacrylate (TMPTA) [83,96,106,109,137], pentaerythritol [50], pentaerythritol tetraacrylate (PETTA) [100], dipentaerythritol hexaacylate (DPHA) and dipropylene glycol diacrylate (DPGDA) [137,141], modified enzymes [134], trimethylolpropane tris(3-mercaptopropionate) (TMPMP) [149] among others can be added during UV-WPUs synthesis.…”

“…The incorporation of inorganic nanoparticles into a UV-WPU matrix is an effective strategy to enhance some properties and provide specific functionalities to this system [152]. Hardness, tensile strength, water absorption, solvent resistance, and thermal behavior of UV-WPUs can be significantly improved by adding nanoparticles like acryloyl chloride modified lysozyme [134], silver [90,157], graphene oxide [107,112,113], surfactant-modified TiO 2 /reduced graphene oxide [45], graphitic carbon nitride [94], and Fe 3 O 4 [70,71]. These nanoparticles also provide excellent antibacterial activity, electrical conductivity, good electronic stability, self-cleaning ability in photocatalysis, and unique magnetic behavior to the coatings.…”

“…Consequently, the UV-curable polymeric dyes with higher functionality are impressive when applied in textiles and other fields. The simple mixture of castor oil-based cationic WPU and acryloyl chloride modified lysozyme, followed by UV-curing, provided the coatings antibacterial properties [134]. Compared to thermally curable coatings, UV-curing technology is considered environmentally friendly, since the formulations release minimal amounts of VOCs and use less energy.…”

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.

In this investigation, the aging behaviors of polyurea coating exposed to marine atmosphere for 150 days were studied and the mechanism was analyzed. The influences on surface and mechanical properties, surface morphology, thermal stability behavior, as well as chemical changes evolution of the coating were investigated. By attenuated total reflectance fourier transform infrared spectroscopy (ATR–FTIR) and X-ray photoelectron spectroscopy (XPS), changes in the chemical properties of polyurea coatings before (PCB) and after 150 d (PCA) of aging were analyzed, and emphasis was given to the effect of aging on functional group change, the hydrogen bonding behavior, and phase separated morphology. The results displayed prominent chain scission during aging, such as N–H, C=O, and C–O–C and the hydrogen bonded urea carbonyl content showed a decrease trend. The relative content of soft and hard segments showed a significant change, which increased the degree of phase separation.

Polyurethane (PU) is a well-known synthetic polymer consisting of isocyanates, polyols, and chain extenders. The incorporation of fillers into the PU polymeric matrix, including inorganic nanomaterials, synthetic polymers, natural components, quaternary ammonium salts, and commercial drugs, bestows the endproducts with unique and improved physicochemical properties. Fillers can be used to tailor the molecular orientation, crystallinity, cross-linking, and functional chemical groups of PU-based composites. The bactericidal ability of PU composites highly depends on their surface composition, morphology, charge, and stability. Recent advancements highlight the potential of PU composites in combating bacterial infections. In this review, the cutting-edge of inorganic and organicbased PU composites for antibacterial applications is addressed. Notably, selective examples of scientific reports' key findings and their crucial information on PU composites are discussed. Furthermore, the positive impact of PU composites on the future prospects of this field is explored. This review comprehensively deliberates the values of PU composites towards practical applications in the biomedical field of antibacterial activity. This review can help researchers to gain widespread knowledge and a better understanding of PU composites for antibacterial applications.
