“…As a whole, for the three kinds of vehicles, a strong band appeared at approximately 2926 cm -1 that was related to the C-H stretch (Rengasamy et al 2013). The characteristic peak near 1743 cm -1 was due to the absorption of the eater group (Zhang et al 2020). In the hybrid LED-UV and vegetable oil-based ink vehicles infrared spectrum, the new peak at 1620 cm -1 corresponded to the stretching vibration peak of the acrylic acid double bond in the hybrid LED-UV vehicles, and 744 cm -1 was the characteristic absorption peak of the epoxy soybean oil epoxy group, which indicated the introduction of acrylic acid double bonds.…”

Waste paper has become a promising raw material for the pulp and paper industry due to its low cost and because it is conducive to sustainable development. Unfortunately, waste paper contains a high volume of printed paper that is difficult to deink, which restricts its applications. Flotation deinking plays an essential role in the product quality and process cost of wastepaper recycling. This study was performed to evaluate the deinkability of environmentally friendly offset inks by flotation deinking. For this purpose, three series of four-color inks, namely, hybrid light emitting diode ultraviolet (LED‒UV), LED‒UV, and vegetable oil‒based inks, were printed on white lightweight coated papers under laboratory conditions. The deinking methodology involves repulping, deinking agent treatment, flotation, hand sheet making, and evaluation of the produced hand sheets. The obtained results indicated that the hybrid LED‒UV prints had the best deinkability. After flotation deinking, the deinking efficiency and the whiteness of the hybrid LED‒UV ink increased by 58.1% and 47.6%, respectively. LED‒UV ink had a 46.9% increase in the deinking efficiency and a 37.0% increase in the whiteness of the hand sheet. The deinking efficiency of the vegetable oil‒based ink was the lowest, at 42.1%, and the whiteness of the hand sheet increased only by 23.8%. The particle size distribution analysis demonstrated that the hybrid LED‒UV four-color ink exhibited a larger value of the average particle size than the two other. Scanning electron microscopy revealed that the hybrid LED‒UV ink particles on the surface of the fibers were the least abundant after deinking. The physical strength properties of the hand sheets, including tensile index, folding resistance, and cohesion of the hybrid LED‒UV, LED‒UV inks, and vegetable oil‒based inks, increased.

“…As reported, the global market of UV-curable materials stood at about $4.6 billion in 2020, which is attributed to their broad applications in fields such as coatings, − packaging materials, , electronics, , 3D printing, , and adhesives owing to their fast curing speed at ambient temperature, low energy consumption, low volatile organic chemical (VOC) emissions, etc. As a kind of important UV-curable material, UV-cured polyurethane acrylates (PUAs) have outstanding performances, including excellent adhesion to substrates, extraordinary flexibility, and excellent abrasion resistance. , However, the mechanical performance and chemical resistance of UV-cured PUAs are limited by the low density and inadequate photosensitive groups of the linear PUA oligomers .…”

“…On the other hand, UV-curable materials are mostly composites of derivatives of petroleum-based raw materials, including reactive diluents, prepolymers, and photoinitiators . However, due to the energy shortage crisis throughout the world due to the depletion of fossil resources and environmental pollution resulting from the petrochemical industry, great efforts have been devoted to substituting petroleum-based materials with renewable materials in the development of UV-curable materials. ,, As a kind of important renewable resource, plant oils have become a preferred selection for the fabrication of UV-curable materials due to their distinguish merits such as low cost, high availability, low toxicity, low viscosity at room temperature, unique triglyceride structure, and ease of modification. − As one of the most widely available vegetable oils, castor oil has attracted increasingly more attention in the fabrication of green and eco-friendly UV-cured materials to improve the mechanical properties, hardness, and water resistance of cured materials because of its unique molecular structure containing unsaturated alkene bonds and hydroxyl groups. − …”

“…Furthermore, the density and content of UV-sensitive groups of the existing UV-curable PUAs are not abundant, which will result in a poor hardness of coatings and a fairly low curing speed. These drawbacks will limit the practical applications of UV-cured PUAs Hyperbranched polymers exhibit high solubility, low solution viscosity, densely branched structure, and a large number of reactive end groups, which will increase the UV curing speed and the hardness of cured materials and reduce the VOC emission of UV-cured coatings for reduction the content of reactive diluents and solvents. − So, hyperbranched polymers are widely used in the preparation of UV-cured PUA coatings.…”

High tensile strength UV-cured transparent materials are highly desired in optical devices. In this paper, high tensile strength UV-cured transparent castor oil-based polyurethane acrylates (PUAs) with a very high transmittance over 95% (400–800 nm) were prepared from UV-curable castor oil-based polyurethane acrylates (CO-PUAs) and mercapto silicone-containing hyperbranched polymers (HBPSHs) under UV irradiation. The tensile strengths of UV-cured transparent castor oil-based PUAs can reach 12.49 MPa, which is obviously higher than that of UV-cured CO-PUAs reported previously (0.7–10.20 MPa). The chemical structure of HBPSHs will play an important role in the mechanical performance of UV-cured silicone-modified materials, and it can be concluded that the more rigid the units of α,β-dihydroxyl derivatives used in the fabrication of HBPSHs are, the higher the mechanical strength and pencil hardness of the UV-cured materials will be.

“…Woody plants oil, such as rubber seed oil, are preferrable for the reason that they don't compete with agricultural food plants for farmland [33]. In our previous work, we acquired hydroxylated woody plant oils via epoxidation and hydroxylation reactions, and then synthesized polyfunctionality oil-based PUA oligomers, and finally produced high-performance woody plant-oils-based UV-cured materials [34]. However, the synthetic procedures for the hydroxylated woody plant oil precursors were complicated, and the oligomers tended to gel at room temperature due to the high amount of carbon-carbon double bonds.…”

Novel UV-curable polyurethane acrylate (PUA) resins were developed from rubber seed oil (RSO). Firstly, hydroxylated rubber seed oil (HRSO) was prepared via an alcoholysis reaction of RSO with glycerol, and then HRSO was reacted with isophorone diisocyanate (IPDI) and hydroxyethyl acrylate (HEA) to produce the RSO-based PUA (RSO-PUA) oligomer. FT-IR and 1H NMR spectra collectively revealed that the obtained RSO-PUA was successfully synthesized, and the calculated C=C functionality of oligomer was 2.27 per fatty acid. Subsequently, a series of UV-curable resins were prepared and their ultimate properties, as well as UV-curing kinetics, were investigated. Notably, the UV-cured materials with 40% trimethylolpropane triacrylate (TMPTA) displayed a tensile strength of 11.7 MPa, an adhesion of 2 grade, a pencil hardness of 3H, a flexibility of 2 mm, and a glass transition temperature up to 109.4 °C. Finally, the optimal resin was used for digital light processing (DLP) 3D printing. The critical exposure energy of RSO-PUA (15.20 mJ/cm2) was lower than a commercial resin. In general, this work offered a simple method to prepare woody plant oil-based high-performance PUA resins that could be applied in the 3D printing industry.
