“…The societal drive to achieve economic and environmental sustainability has led to an increased emphasis on the use of alternative environmentally friendly, bio-based products from biorenewable resources or biomass. − Fabrication of new classes of engineering materials with outstanding mechanical, thermal, dielectric, and biological properties from bio-based sustainable products has received considerable attention recently. − Plant oils are the most abundant and cost-effective biorenewable resources worldwide. − They have been widely used to synthesize bio-based polymers with no toxicity and inherent biodegradability. − Saturated and unsaturated fatty acids are the main components of triglyceride vegetable oils that are the platform chemicals for polymer synthesis. Seeds of the tung tree have large quantities of tung oil, which contains approximately 84% α-eleostearic acid triglyceride with a large number of conjugated CC bonds .…”

Nanoscale semi-interpenetrating polymer networks of bio-based poly(εcaprolactone) (PCL) and polymerized tung oil have been prepared via in situ cationic polymerization and compatibilization in a homogeneous solution. This novel blending technique produced a nanoscale morphology of poly(ε-caprolactone) with average particle sizes as small as 100 nm dispersed in a cross-linked tung oil matrix for 20 and 30 wt % PCL blend compositions. In addition, the exothermic cationic polymerization of tung oil in the presence of the PCL homogeneous solution created a microporous morphology with open threedimensional interconnected cluster structures. The porous morphology was found to be composition-dependent (the pore size and interconnectivity decreased with increasing PCL content in the blend). The values of the cross-link density and storage modulus in the glassy state for fully cured samples increased significantly and reached a maximum for the 20 wt % PCL blend. This simple, versatile, low-cost strategy for preparing nanoscale and interconnected three-dimensional cluster structures with a microporous morphology and desired properties should be widely applicable for new polymer systems.

“…By reacting with (meth)acryloyl chloride or methacrylate anhydride, plant oils can be transformed into polymerizable monomers for free radical polymerization. Recently, two soybean oil-based sustainable monomers, SOM1 and SOM2, were designed and used by Wang and coworkers to produce Cell-g-P(SOM1-co-SOM2) copolymers via ATRP [61]. By changing the molar ratios of SOM1/SOM2 during grafting polymerization, the glass transition temperatures (T g s) of resultant cellulose graft copolymers varied from 40.7 to À0.7°C.…”

This chapter is concerned with the recent progress in cellulose-based thermoplastic plastics and elastomers via homogeneous controlled radical polymerizations (CRPs), including atom transfer radical polymerization (ATRP), reversible addition-fragmentation chain transfer (RAFT) polymerization, and nitroxidemediated polymerization (NMP). The first section is a brief introduction of cellulose and cellulose graft copolymers. The second section is recent developments in cellulose graft copolymers synthesized by CRPs. The third part is a perspective on design and applications of novel cellulose-based materials. The combination of cellulose and CRPs can provide new opportunities for sustainable materials ranging from thermoplastics to elastomers, and these fascinating materials can find a pyramid of applications in our daily life in the near future.

“…Although an excellent option with respect to degradability, an argument against plant oil polymers is that their mechanical performance may not always be favorably compared to those of traditional plastics. − Nanomaterials have been demonstrated to significantly modify a polymer’s physical properties, and cellulose nanocrystals (CNCs) have specifically been used in numerous plant oil polymerization studies, e.g., in reactions with ESBO-based resins, polyurethanes, and (meth)acrylate polymers, UV-cured acrylated ESBO thermosets, sunflower-derived epoxy polymers, castor oil-based polyurethanes, − and resins from tung-oil . Because of CNCs’ excellent tensile strength (greater than that of Kevlar), significant improvements in mechanical properties have been observed with the incorporation of CNCs.…”

The detrimental issues surrounding the accumulation of traditional plastic waste are well known. A myriad of research has been conducted in the past few decades related to the synthesis of polymers using plant oils as starting monomers to obtain polymers from renewable sources. These polymers can be biodegradable and, therefore, can decrease further plastic waste accumulation. Although many studies have been conducted on the polymerization of soybean oil (SBO), comparatively few studies have been conducted on the polymerization of cottonseed oil (CSO). CSO is an excellent candidate for a plant-based polymer due to the abundance, renewability, and potential biodegradability of the synthesized polymers. We have synthesized cottonseed oil network polymer (CNP) from epoxidized cottonseed oil (ECSO) using maleic anhydride (MAL) as a crosslinker. Further, cellulose nanocrystals (CNCs) have been successfully incorporated into CNPs to produce a nanocomposite. Neither solvent exchange of the aqueous CNCs nor surface compatibilization was required before mixing with the ECSO and subsequently with maleic anhydride (MAL). FTIR confirmed the presence of CNCs in the polymer matrix, and the effects of CNCs on the mechanical properties were investigated. CNCs alter the mechanical properties of the crosslinked polymer, with an increase in stiffness/modulus correlating with an increasing CNC content. The polymer's thermal properties, as investigated by thermodynamic analysis and differential scanning calorimetry, have not undergone significant changes for the CNC concentrations considered here. Overall, this study demonstrates that CNC can be successfully incorporated into a network polymer derived from CSO, resulting in altered mechanical properties and demonstrating the possibility of tailoring them for various applications.
