“…Another common way to adjust the properties of AESO-based materials is the incorporation of co-monomers. Styrene [83][84][85][86], N-vinyl-2-pyrrolidone (NVP) [64,87], 3-isopropenyldimethylbenzyl isocyanate (TMI) [88], isocyanatoethyl methacrylate (IEM) [88], 1,6-hexanediol diacrylate [89], divinylbenzene [86,89] and unsaturated polyester [90-94] are widely used as co-monomers for AESO. The diblock copolymers based on AESO and styrene are able to work as an additive for asphalt to modify the rheological performance so that the corresponding stiffness, elasticity and rutting resistance of the asphalt can be substantially improved [83].…”

Epoxidized soybean oil (ESO) is the oxidation product of soybean oil with hydrogen peroxide and either acetic or formic acid obtained by converting the double bonds into epoxy groups, which is non-toxic and of higher chemical reactivity. ESO is mainly used as a green plasticizer for polyvinyl chloride, while the reactive epoxy groups imply its great potential in both the monomer synthesis and the polymer preparation fields. Functional polymers are obtained by different kinds of reactions of the ESO with co-monomers and/or initiators shown in this chapter. The emphasis is on ESO based epoxy cross-linked polymers which recently gained strong interest and allowed new developments especially from both an academic point of view and an industrial point of view. It is believed that new ring-opening reagents may facilitate the synthesis of good structural ESO based materials.

“…AESO contains a variety of functional groups, including carbon double bonds (CC), hydroxyl groups, and epoxy groups; thus, it is easily functionalized with other monomers. AESO has been used in industrial thermosetting biopolymer productions, such as coatings, plasticizers, adhesives, and asphalt modifiers. − However, there is less literature about the use of AESO in BFs to form strong connections with the asphalt matrix. In this study, AESO was grafted onto the BF surface by using 4,4-methylenediphenyl diisocyanate (MDI) as a linker.…”

Bamboo fibers (BFs) have attracted much attention as a potential sustainable reinforcement material for asphalt pavements due to their high specific strength and modulus, low cost, renewability, and biodegradability. However, the key challenge of using BFs in asphalt mixtures is the weak interfacial adhesion between intrinsically hydrophilic BFs and the hydrophobic asphalt matrix. Therefore, this study proposed a surface modification method of BFs using acrylated epoxidized soybean oil (AESO) and 4,4-methylenediphenyl diisocyanate (MDI) to improve the fiber− matrix adhesion of the BFs/asphalt mixture. Fourier transform infrared spectroscopy and nuclear magnetic resonance analyses confirmed that the modified BF surface was grafted with AESO, and both of them were linked by MDI, thereby leading to the formation of a hydrophobic layer on the fiber surface. The water absorption of BFs significantly decreased after modification, and the interfacial adhesion between the modified BFs and the asphalt matrix remarkably improved. Adding the modified BFs to the mixture improved its mechanical properties, high-temperature stability, and low-temperature cracking resistance and decreased its moisture susceptibility. The work provides a feasible and industrial-scale method to enhance the road performance of the asphalt mixture by using renewable natural fibers and vegetable oils as modifying materials.

“…[ 13 ] In addition, acrylated epoxidized soybean oil (AESO) is also widely used in composite materials. Many researchers focused on the cross‐linking reaction of AESO through free radical polymerization by initiation of double bonds using ultraviolet light, [ 14 ] and the corresponding cured products have been commercially used in coatings. [ 15 ] In addition, AESO is a multifunctional feedstock to make bio‐based thermoplastic polymers.…”

Poly(acrylated epoxidized soybean oil) (PAESO) has been grafted on the surface of multiwalled carbon nanotubes (MWCNTs) by reversible addition–fragmentation chain‐transfer reaction (RAFT). MWCNTs–PAESO as reinforcement has been successfully applied to prepare epoxidized soybean oil/maleopimaric‐based thermosetting composites with good dispersion through probe ultrasonic treatment in ethyl acetate. Micromorphology analyses on composites by transmission electron microscopy and scanning electron microscopy show that MWCNTs–PAESO has better dispersion stability in both ethyl acetate and epoxy matrix and better interface bonding effect with cured matrix, resulting in more uniformly and separately dispersed behavior than hydroxylated multiwalled carbon nanotubes. Correspondingly, by the method of molecular dynamics simulation, it is verified that the nonbond energy and van der Waals force of CNTs–PAESO in solvent can be relatively reduced, and that CNTs–PAESO possesses higher binding energy with matrix compared with CNTsOH. Therefore, MWCNTs–PAESO and PAESO have synergistic enhancement on the mechanical properties of composites demonstrated by rheology testing and dynamic mechanical analysis. The appropriate amount of MWCNTs–PAESO loading at 0.15 wt% can increase the glass transition temperature (Tg) of thermoset from 83.8 to 96.3°C, resulting in the improvement of both mechanical and thermal properties. These results show that surface‐grafting MWCNTs with homologous polymer can effectively increase the interfacial compatibility between matrix and MWCNTs, thereby improving the thermal and mechanical properties of composites.
