“…With the increasing concern about global environmental issues, how to reduce the carbon footprint to achieve carbon neutrality has been particularly important. To overcome this challenge, sustainable polymers derived from renewable resources have attracted great attention because of their huge potential to replace nonrenewable fossil-based incumbent polymers. − As the second most abundant natural biomass after cellulose, lignin has been frequently used as functional bioresource fillers to fabricate green composite materials with enhanced properties. − Alternatively, lignin can be utilized as the raw material to produce biobased aromatic-containing platform compounds, such as vanillin, syringol, guaiacol, eugenol, and syringic acids, offering new avenues for the preparation of lignin-based sustainable polymer materials . Due to the existence of a bulky aromatic ring side group, lignin-based methacrylate or acrylate monomers are ideal rigid segments to prepare the glassy blocks in elastomers .…”

With the increasing concern about global environmental issues, reducing the carbon footprint to achieve carbon neutrality has been particularly important. Sustainable multiblock copolymer elastomers (MBCPEs) have received tremendous interest due to their unprecedented performance and huge potential applications. However, complex multistep polymerization and postpolymerization processes are needed to design MBCPEs. In this work, a series of MBCPEs, in which vanillin acrylate (VA) derived from lignin was selected as the renewable rigid segments for the glassy block, while methyl acrylate (MA) was chosen as the soft segments for the rubbery block, were prepared by two successive reversible addition–fragmentation chain transfer (RAFT) polymerization processes with polytrithiocarbonate (PTTC). These thermally stable MBCPEs exhibit distinct microphase-separated morphology, where the hard poly(vanillin acrylate) (PVA) blocks self-assemble into discrete glassy domains serving as the physical cross-linking points in the soft poly(methyl acrylate) (PMA) matrix. The macroscopic mechanical performance, such as tensile strength, stretchability, toughness, and elastic recovery, can be adjusted well by changing the molecular weights and PVA contents. Moreover, these sustainable MBCPEs can be applied as strong adhesives and excellent UV-shielding materials, broadening their potential applications. This novel strategy is convenient and robust by combining RAFT polymerization and renewable resources toward high-performance MBCPEs, which can open a new avenue for the development of sustainable biobased elastomers.

“…However, it should be noted that the G p value drops from 251.3 MPa for MBCPE@Fe 3 O 4 1.0 to 195.8 MPa for MBCPE@Fe 3 O 4 5.0 as the Fe 3 O 4 content increases from 1.0 to 5.0 wt % due to the reduced stretchability. To further evaluate the contributions of Fe 3 O 4 microparticles to MBCPE@Fe 3 O 4 composite elastomers, the interfacial interaction was investigated by using the Mooney–Rivlin equation , σ * = σ normale normaln normalg / ( λ − λ − 2 ) = 2 C 1 + 2 C 2 λ − 1 where σ* is the reduced stress, C 1 is a constant related to the material, and C 2 is a constant related to strain softening ( C 2 > 0) or strain hardening ( C 2 < 0). The changes in σ* as a function of λ –1 for MBCPE, MBCPE@Fe 3 O 4 1.0, MBCPE@Fe 3 O 4 2.5, and MBCPE@Fe 3 O 4 5.0 are plotted in Figure h.…”

Sustainable elastomers with high strength and unique functions are highly desired yet challenging. In this work, multiblock copolymer elastomers (MBCPEs) were synthesized by two sequential reversible addition−fragmentation chain transfer polymerization procedures with polytrithiocarbonate (PTTC) as the chain transfer agent and lignin-derived monomer vanillin acrylate as the rigid segment for the glassy blocks. Furthermore, magnetite (Fe 3 O 4 ) microparticles were introduced into the as-prepared MBCPE to fabricate magnetic MBCPE@Fe 3 O 4 composite elastomers. These composite elastomers exhibit significantly enhanced mechanical properties due to the excellent interfacial interaction between the microparticles and the matrix via the Schiff-base reaction. Besides, MBCPE@Fe 3 O 4 composite elastomers show outstanding adhesion performance, magnetothermal behavior, and photothermal properties. Under near-infrared irradiation, the composite elastomers display rapid stimulus-healing and actuating phenomena via fast photothermal conversion. The combination of sustainable MBCPEs and functional microparticles can provide great potential for the development of intelligent materials with unique stimulus-responsive applications.

“…Hitherto, high-performance poly(oxalamide) elastomers, characterized by their exceptional strength and toughness, have rarely been reported because strong HB interaction may result in excessive supramolecular aggregation . Besides, other sustainable compounds, such as methyl 10-undecenoate, ,− 2,5-furandicarboxylic acid, , itaconic acid, , 1,3-propanediol, fumaric Acid, Priamine 1075 and Pripol 1009, thermoplastic starch, , cellulose, lignin etc., have also been used in the design and preparation of TPEs. Although considerable progress has been made in the manufacture of sustainable TPEs, simultaneously achieving mechanical robustness and toughness in biobased TPEs continues to pose a significant challenge.…”

Harvesting sustainable biobased elastomers with both high strength and high toughness holds great promise for various applications. However, the inherent conflicts between these properties make it challenging to achieve a simultaneous balance. Here, inspired by the structure of spider silk, we have synthesized a multiphase polymer (PA-BP x ) containing oxalamides derived from biomass. The introduction of a benzene ring structure, combined with the double hydrogen bonds of oxalamide, results in smaller and more uniformly distributed hard domains, concurrently enhancing the molecular chain rigidity. The molecular structure described facilitates energy dissipation through the destruction and reformation of hard domains, achieving a remarkable balance between superior mechanical robustness and toughness. The PA-BP 40 elastomer demonstrates exceptional advantages in both tensile strength and toughness compared to other reported biobased and filled biobased elastomers, with a toughness of 230 MJ•m −3 and maintaining a high tensile strength of 46.6 MPa. These remarkable mechanical properties make the PA-BP 40 elastomer a promising material for various applications where both high strength and toughness are required. Moreover, the elastomers exhibit strong fluorescence even in the absence of conventional chromophores, highlighting their potential for fluorescent anticounterfeiting applications. Overall, this study presents a promising strategy for developing sustainable elastomers with desirable performance characteristics, thus contributing to the advancement of biobased materials in various applications.
