Waste soybean oil resulting from repeated cooking and heating is a significant component of food industry waste. Transforming this waste soybean oil into eco-friendly and various products offers an efficient solution to enhance resource utilization. This study employed thermal cycling treatment to simulate the cooking process of soybean oil and analyzed its impact on synthesizing epoxidized soybean oil, soybean oil polyols , and soybean oil-based waterborne polyurethanes . Waste soybean oil was demonstrated to be a cost-effective feedstock for producing vegetable oil-based waterborne polyurethanes . For more diversified applications, the synthesized waterborne polyurethanes were utilized in the preparation of carbon quantum dots , resulting in a diverse range of colors through the incorporation of gardenia pigments. Moreover, through complexing with gelatin, robust composite films and multicolored fluorescent anti-counterfeiting inks were produced. The waterborne polyurethane is found to form a composite cross-linking network with gelatin, resulting in an increase in tensile strength of 130.72% and elongation at break of 258.98% for the composite film compared to the pure gelatin film. In comparison to physical blending, chemical grafting of gardenia pigment enhances the printability and firmness of the ink. The printed pattern produced by the ink emits a vivid blue fluorescence when excited at a wavelength of 365 nm, making it valuable for anti-counterfeiting ink applications.

In this study, we investigated the inhibitory effects of three soybean isoflavones and two soybean phytosterols on the formation of 3-chloropropane-1,2-diol fatty acid esters (3-MCPDE) and aldehydes in heated soybean oil model. 0.4 mM of genistin, genistein, daidzein, stigmasterol, and β-sitosterol significantly reduced 3-MCPDE formation by 25.7, 51.4, 21.4, 61.6, and 55.7%, and total aldehydes formation by 42.03, 43.94, 28.36, 54.74, and 39.23%, respectively. Further study showed that stigmasterol reduced the content of glycidyl esters (GEs) and glycidol, two key intermediates of 3-MCPDE, and prevented fatty acids degradation in the oils. Moreover, the effects of continuous frying time on the content of stigmasterol and the migration of stigmasterol were evaluated in the fried dough sticks model system. The content of stigmasterol in soybean oil was found to be significantly decreased with prolonged heating time. The concentrations of stigmasterol in fried dough sticks and the migration rates of stigmasterol from soybean oil to fried dough sticks decreased with repeated frying sessions. In addition, stigmasterol undergoes oxidative changes during heat treatment, and the oxidation products including 5,6α-epoxystigmasterol, 5,6β-epoxystigmasterol, 7α-hydroxystigmasterol, 7β-hydroxystigmasterol, stigmasterlol-3β,5α,6β-triol, and 7-ketostigmasterol were identified in the frying oils but not in the fried dough sticks. Overall, stigmasterol could be added to soybean oil to reduce 3-MCPDE and aldehydes formation, and reacting with GEs/glycidol and protection of lipid acids from oxidation may be the mechanism of action of stigmasterol.

In this work, a novel soybean oil-based urethane acrylate polyol called ADSO was synthesized by the condensation reaction of hydroxyethyl acrylate modified isophorone diisocyanate with chlorinated soybean oil (SOL). The soybean oil-based waterborne polyurethane called ADSO-WPU was prepared with SOL and ADSO as polyols. Using the carbon-carbon double bonds of ADSO-WPU as reaction sites, methyl methacrylate (MMA), butyl methacrylate (BA) and 2-(perfluorohexyl)ethyl methacrylate (PFOMA) were grafting copolymerized to obtain the soybean oil-based waterborne polyurethane grafted fluorine-containing acrylate (ADSO-PUA). The results of Fourier transform infrared spectrometer, dynamic light scattering analyzer and transmission electron microscopy showed that the grafted copolymer latex was successfully prepared with particle size of about 100–300 nm. Furthermore, effects of the ratio of PFOMA, MMA and BA on properties of grafted copolymer films were studied. Compared with ADSO-WPU film, ADSO-PUA film had significantly lower water absorption, higher hardness, better mechanical properties and higher thermal stability. With the increase of PFOMA content, the water absorption rate decreased from 108% to about 10%, the hardness increased from 4H to 6H, and the tensile strength increased from 3.05 MPa to 9.79 MPa.

Guided by efficient utilization of natural plant oil and sulfur as low-cost sorbents, it is desired to tailor the porosity and composition of polysulfides to achieve their optimal applications in the management of aquatic heavy metal pollution. In this study, polysulfides derived from soybean oil and sulfur (PSSs) with improved porosity (10.2–22.9 m 2 /g) and surface oxygen content (3.1–7.0 wt.%) were prepared with respect to reaction time of 60 min, reaction temperature of 170 °C, and mass ratios of sulfur/soybean oil/NaCl/sodium citrate of 1:1:3:2. The sorption behaviors of PSSs under various hydrochemical conditions such as contact time, pH, ionic strength, coexisting cations and anions, temperature were systematically investigated. PSSs presented a fast sorption kinetic (5.0 h) and obviously improved maximum sorption capacities for Pb(II) (180.5 mg/g), Cu(II) (49.4 mg/g), and Cr(III) (37.0 mg/g) at pH 5.0 and T 298 K, in comparison with polymers made without NaCl/sodium citrate. This study provided a valuable reference for the facile preparation of functional polysulfides as well as a meaningful option for the removal of aquatic heavy metals.

A new carbon precursor, soybean oil, was applied to the synthesis of ordered mesoporous carbon (SOMC) using an inverse replication method in conjunction with ordered mesoporous SiO 2 molecular sieves (SBA-15) as a hard template. The effects of different carbonization temperatures (600, 700, and 800 °C) on the microstructure, degree of order of the pore structure, specific surface area, and pore size of the SOMC were investigated. Scanning electron microscopy showed that the SOMC was composed of rods approximately 1 μm in length and 0.5 μm in diameter. Transmission electron microscopy indicated that carbonization temperatures in the range of 600–800 °C produced, the SOMC samples having a suitably ordered mesoporous structure. N 2 adsorption–desorption analysis confirmed that the Brunauer–Emmett–Teller specific surface area of the SOMC was 882 m 2 /g with a pore diameter of 3.5 nm after processing at 600 °C.

Blends of entirely bio-sourced polymers, namely polylactide (PLA) and starch, have been melt-compounded by lab-scale co-extruder with epoxidized soybean oil (ESO) as a reactive compatibilizer. The starch granules were grafted with the maleic anhydride (MA) to enhance its reactivity with ESO. The ready reactions between the epoxy groups on ESO, the MA groups on MA-grafted starch (MGST) and the end carboxylic acid groups of PLA brought blending components together and formed a compatible compound. An elongation at break (EB) of 140% was obtained in the blend of PLA/MGST/ESO (80/10/10), increased from 5% of a pure PLA. The grafting content of the MA on the starch granules primarily determined the compatibility and properties of the ternary blends, which was also affected by the relative amount of MGST and ESO.

Developing sustainable 3D printing materials has attained intensive interest due to the rapid growth of the 3D printing industry and the concerns on depletion of fossil resources and environmental pollution. In this work, a novel biobased UV-curable oligomer (GMAESO) was firstly synthesized from epoxidized soybean oil (ESO) and gallic acid (GA) via a ‘green’ one pot method. The obtained biobased oligomer possessed a biobased content of 82.9%. By co-photopolymerization of the obtained oligomer with a hydroxyethyl methacrylate (HEMA) diluent, a series of UV-curable materials were prepared, and their properties as well as curing behaviors were investigated. Notably, the resulting GMAESO resins with high HEMA contents (50–60%) showed low viscosities (52–93 mPa s) and excellent thermal and mechanical properties (a Tg of 128–130 °C, Tp >430 °C, a tensile strength of 42.2–44.4 MPa, etc.) which were comparable or superior to a commercial product. Furthermore, the optimal resin (GMAESO with 50% HEMA) was used for digital light processing (DLP) 3D printing. The resin showed lower penetration depth (0.277 mm) than the commercial resin, thus different-structured objects with high resolution were successfully printed. In general, the developed bio-based UV-curable resins are very promising for application in the 3D printing industry.

The utilization of soybean oil-based UV coatings depends on the introduction of petroleum-based comonomers or crosslink agents. Thus, in this paper, a bio-based crosslink agent (GACA) for UV curable coatings was synthesized from gallic acid and its chemical structure was confirmed by FT IR, 1H NMR and 13C NMR. Crosslinked networks with high biobased content of more than 88% were obtained after co-photopolymerization between acrylated epoxidized soybean oil (AESO) and GACA. The thermal, mechanical and coating properties of these GACA crosslinked AESO networks were investigated and a commonly used crosslink agent triallyl isocyanurate (TAIC) was used as the control. GACA exhibited more functional groups and better copolymerization with AESO than TAIC, resulting in the higher gel content, crosslink density, tensile strength and modulus as well as much better coating properties (reflected by the higher pencil hardness, better wear resistance and adhesion) of GACA crosslinked AESO networks than TAIC crosslinked AESO networks. These results indicated that GACA exhibited great potential to replace petroleum-based crosslink agents such as TAIC, and high-performance soybean oil-based UV-cured coatings with high biobased content could be achieved after introducing GACA.

In order to improve the flexibility properties of conventional epoxy resin, two novel soybean oil–based curing agents were synthesized. The curing agent obtained from the reaction between epoxy soybean oil and ethylene diamine was named EEDA, and another curing agent derived from epoxy soybean oil and isophorone diamine was named EIPDA. Several techniques were used to systematically investigate the effects of the structure and content of the two curing agents on the properties of the cured products. The Fourier transform infrared analysis demonstrated that epoxy resin reacted with soybean oil–based curing agents. The differential scanning calorimetry analysis showed that the curing process between diglycidyl ether of bisphenol-A (DGEBA) and soybean oil–based curing agents only had an exothermic peak. Thermogravimetric analysis indicated that the cured DGEBA/EIPDA system was more stable than the DGEBA/EEDA system below 300 °C. Mechanical tests and Shore D hardness tests suggested that excessive EEDA greatly enhanced the toughness of cured products because of the introduction of aliphatic chains.© 2017 Wiley Periodicals, Inc.

In this study, epoxidized soybean oil was modified to prepare acrylated epoxidized soybean oil (AESO) and vinyl/acrylate ended soybean oil (VASO), which were blended with mercaptopropyl polyhedral oligomericsilsequioxane (POSS-SH) to prepare UV curable thiol-acrylate and thiol-ene-acrylate hybrid coatings. Photopolymerization processes of the coatings were measured and the results showed that addition of POSS-SH obviously increased the conversion of double bond. The physical and mechanical properties of all cured samples were investigated, which indicated that the pencil hardness, tensile strength, and fracture toughness were significantly improved by POSS-SH. Moreover, with increasing POSS-SH content, the water contact angles of cured samples were increased, and the water resistance was greatly improved. © 2015 Wiley Periodicals, Inc. J. Appl. Polym.

Soybean oil containing thioxanthone (TX) moieties and/or coinitiator DBA (ESO-ATX-DBA, ESO-ATX/ESO-DBA) were synthesized by grafting 2-acitic thioxanthone (ATX) and 4-(dimetheylamino) benzoic acid (DBA) to the backbone of epoxidized soybean oil (ESO). The obtained ESO-ATX-DBA, ESO-ATX and ESO-DBA were characterized by FT–IR, 1 H NMR and UV–vis spectra, and investigated as photoinitiators by photo-DSC. Photoinitiator systems ESO-ATX-DBA and ESO-ATX/ESO-DBA were more efficient than their low-molecular weight analogues (chemical mixture of ETX-DBA and physical mixture of ETX/EDB) especially in the photopolymeriztion of acrylate monomers containing pigment. Moreover, ESO-ATX-DBA exhibited much lower migration in comparison with their low-molecular weight analogues. These characteristics gave the obtained TX containing soybean oil potential in the application of ink, and these studies also provide alternative approach to prepare polymeric photoinitiators from the renewable source.

We report on an efficient method for the formation of modified cellulose-based materials with enhanced hydrophobic properties, formed by grafting with polymeric epoxidized soybean oil (ESO) as a renewable, environmentally friendly, and low cost raw material. The grafting process occurred via ring-opening polymerization, wherein the cellulose hydroxyl groups acted as initiators in the presence of a SnCl4 catalyst, linking the cellulose fibers and ESO via ether linkages, thereby forming a polymeric matrix. The surface polarity was therefore decreased by the substitution of cellulose hydroxyl groups for long-chain hydrophobic alkane moieties from ESO. The water contact angle of modified filter paper reached 145.1° with the surface free energy decreasing to 22.07 mJ m–2 and a hydration free energy of −13.09 mJ m–2. The presence of polymeric ESO nanoparticles on the modified cellulose fibers suggested that the hydrophobicity was not only dependent on the surface composition but was also closely related to the surface morphology. To reveal the effects of surface morphology on hydrophobicity, smooth cellulose films anchored to mica plates via PVAm with a surface roughness of 1.698 nm were prepared by spin coating and modified with ESO. The thus-formed modified cellulose films also contained polymeric ESO nanoparticles which increased their roughness and enhanced their hydrophobic properties.
