“…The properties of PU, including the hardness and softness, can be tailored by adjusting the quantities and types of isocyanates and polyols used in the synthesis process. In addition, the final material can be modified by incorporating additives such as flame retardants, 61 moisture scavengers, 62 surfactants, 63 pigments, 64 and blowing agents. 65…”

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.

“…Studies of UV-cured acrylates have reported that curing occurs via the decrease and disappearance of the vibration peaks of the C=C double bonds. The absorption peaks of vibration of the C=C double bond appear at 810, 840, and 950 cm‫,¹-‬ stretching over the range of 1410 to 1420 cm‫¹-‬ [26,3435]. In Figure 3, the decrease and disappearance of the twisting peak at 810 cm‫¹-‬ and the stretching peak at 1410 cm‫¹-‬ reveal that polymerization occurred after the UV-curing process.…”

“…The cured ink film was analyzed to confirm the occurrence of UV-curing as the decrease and disappearance of the twisting peak at 810 cm‫,¹-‬ and a stretching peak at 1410 cm‫¹-‬ represented the polymerization that occurred after the UV-curing process [25,26,34]. The UVcurable ink was printed and cured on 2-mm acrylic plates in pale blue PANTONE P115-4C…”

“…Baysal et al showed that the color value of the UVcured samples was changed significantly when the proportions of the photo-initiator were changed [25]. The pigment color in the ink also affected the curing degree of the printed films because the UV absorption/transmission intervals of each color differed [26]. Hakeim et al studied UV-curable inkjet inks for textile printing application, and the printed fabrics exhibited soft handling and desirable fastness properties [18].…”

As the use of textile polypropylene (PP) fibers becomes more common in commercial textiles and sportswear, the investigation of the effects of UV-curable ink on the heat-sensitive PP knitted fabrics is crucial to optimize functional clothing design. This study investigated the effects of UV-curable ink on the heat-sensitive PP knitted fabrics when the ink was cured using UV light at room temperature, to avoid degradation of the PP fabric by high temperature, and provided an alternative coloring method for PP fabric used in sportswear. The influences of printing parameters such as the printing distance, number of overprints, and color of ink on fabrics as well as aesthetic, physical, and low-stress mechanical properties in terms of tensile, bending, shearing, surface, and compression were systematically investigated. The results indicated that the physical properties and low-stress mechanical properties of PP fabrics printed with UV-curable ink were significantly affected by the number of overprints and the color of the prints, whereas the color appearance was affected mainly by the number of overprints and the printing distance. In terms of the fabric's hand value, only 2HB and 2HG5 were significantly affected by the number of overprints and the color of the prints, with the prediction rate exceeding 40% among the low-stress mechanical properties. The fabric's hand value was not significantly affected by the thin UV-cured ink film when compared with the fabric itself. Fabric printed in a color with the greatest lightness and the fewest overprints had the lowest fabric weight, thickness, and color difference (∆E) towards the reference color, in addition to better bending recovery and resilience properties. The new knowledge from this study can provide an alternative coloring method for PP knitted fabric to increase the design variety available to textile designers who use PP fabric. The results from this study contribute to the textile and knitwear design industry.

The development of self‐healing materials is an effective strategy to improve the service life of polymer materials. In this study, self‐healing waterborne fluorinated polyurethane‐acrylate (WFPUA) containing UV‐responsive coumarin groups was prepared by Pickering emulsion polymerization using modified cellulose nanocrystal as a stabilizer. The effect of double bond‐terminated waterborne polyurethane (WPU) content on emulsion polymerization and latex film properties was mainly studied. Due to the dynamic reversibility of the coumarin groups and the synergistic effect of hydrogen bonds, the optimized sample (WFPUA‐30) had excellent mechanical properties and self‐healing properties. The tensile strength was 5.24 MPa, and the elongation at break was 267%. The self‐healing efficiency of tensile strength and elongation at break after 6 h of repair were 86.52% and 93.20%, respectively. In addition, due to the presence of fluorine‐containing groups, the water and oil contact angles of the latex film could reach 101.7°and 82.1°, respectively. This work broadens the way to manufacture self‐healing and multifunctional waterborne polyurethane‐acrylates.
