“…This global decarbonization campaign has a significant effect on the rubber industry. Scientists have developed elastomer materials based on bio-based monomers, such as bio-based itaconate elastomers, − bio-based fumarate elastomers, bio-based degradable polyester elastomers, , and bio-based polyamide thermoplastic elastomers. , Compared to petroleum-based rubbers, these novel bio-based elastomers are not only independent of fossil resources but also have versatile properties due to their unique structures. With the development of bio-based monomers, it is foreseeable that these bio-based elastomers will have a broad application prospect.…”

Most rubber products come from petrochemical resources, which are increasingly in short supply. Rubber products that formed irreversible chemical bonds in the vulcanization process are difficult to recycle, resulting in a serious waste of resources. Therefore, it is important to prepare a kind of reprocessable biobased elastomers. Using furfuryl methacrylate (FMA) as the modified monomer, poly(dibutyl itaconate-myrcenefurfuryl methacrylate) (PDBIMFA) was synthesized by hightemperature emulsion polymerization successfully. The structure and compositions of PDBIMFA were characterized by Fourier transform infrared and 1 H NMR, and the effects of different FMA contents on the structures and properties of PDBIMFA were systematically studied. Based on the Diels−Alder reaction, bismaleimide (BMI) and carbon black (CB) were introduced into PDBIMFA as cross-linking agents and reinforcing fillers, respectively, by the melt blending method, and PDBIMFA-BMI elastomer materials and CB/PDBIMFA-BMI elastomer composites with thermo-reversible cross-linking characteristics were prepared. The effects of the ratio of FMA and BMI on the mechanical properties of PDBIMFA-BMI were studied. PDBIMFA-BMI and CB/PDBIMFA-BMI were reprocessed twice, and the recovery rate of tensile strength was both more than 90%. The addition of CB was found to play a reinforcing role in the elastomer and with the introduction of the amount of CB, the reprocessability of composite remained at a good level. It is hoped that this research will provide a new strategy for the sustainable development of bio-based elastomer materials.

“…In our previous work, various biobased polyester elastomers (BPEs) were synthesized with diverse properties. [7,[32][33][34][35][36][37][38][39][40][41][42] As for oil resistant application, BPE possesses innate advantages endowed by the numerous ester groups in their main molecular chains. Compared with NBR and ACM, it is feasible to adjust the oil resistance of BPEs via choosing diverse bio-based diols and diacids with different chain length.…”

Polarity determines the oil resistance property of elastomers. In this work, three bio‐based polyester elastomers (BPEs) with different mass fraction of ester groups (E) are designed and synthesized aiming to study the relationship of E and oil resistance performance, and to obtain bio‐based elastomer materials with tunable oil resistance. Through adjusting the chain length of monomers, E of poly(ethylene glycol/1,3‐propanediol/succinate/adipate/itaconate)(PEPSAI), poly(1,3‐propanediol/1,4‐butanediol/succinate/adipate/itaconate)(PPBSAI), and poly(1,3‐propanediol/1,4‐butanediol/sebacate/adipate/itaconate)(PPBSeAI) are ≈50.39%, 48.55%, and 39.68%, respectively. Results show that E has great influence on the oil resistance of BPEs. After being immersed in IRM‐903# oil for 72 h at room temperature, the changes in mass and volume of BPEs decrease along with the increasing mass fraction of ester groups, indicating improved oil resistance performance. PEPSAI with the highest mass fraction of ester groups presents better oil resistance and lower Tg (better low‐temperature resistance) than one of the most used commercial oil‐resistant rubber nitrile rubber (N230S). Thus, this work provides a promising strategy to obtain bio‐based oil resistant elastomers with practical value.

“…Interestingly, Zhang and co-workers systematically investigated a series of polyester elastomers utilizing bio-monomers or bio-derived monomers. The tensile strength and elongation at break can be controlled in the ranges of 1.2-16.0 MPa and 70%-800%, respectively, and such polyester elastomers also show excellent biocompatibility and promising applications in in-vivo soft tissue repair [31][32][33][34] . However, there has still been less work on the use of polyester elastomers in soft electronics.…”

Although soft electronic materials are of significant importance for flexible electronic devices, most of them are derived from commercial polymer elastomers, such as polydimethylsiloxane, polyurethane and Ecoflex. In this work, citric acid-based degradable polyester elastomers are prepared by a melt polycondensation process, utilizing citric acid, 1,8-octanediol and poly(ethylene glycol) (PEG) as monomers. Furthermore, poly(1,8-octanediol citrate acid) (POC)-PEG/silver nanowire (AgNW) conductive polyester elastomers (CPEs) are prepared by introducing a AgNW layer on the surface of the POC-PEG films. Scanning electron microscopy images reveal that the thickness of the AgNW layer is on the scale of several micrometers and the AgNWs form a continuous conductive network. Upon mechanical stimuli, POC-PEG exhibits recoverable deformation and induces variation in the AgNW conductive network, resulting in a conversion of strain to detectable resistance. When tensile strain is applied, the POC-PEG/AgNW CPEs achieve a gauge factor of 231.6, a response range of 0%-50%, a low response time of 35 ms and high stability. Moreover, the POC-10PEG/AgNW CPE also responds to bending deformation with a gauge factor of 3667.5, a response range of 0%-8.4%, a low response time of 62 ms and high stability. On the basis of strain sensitivity, wireless sensors are further assembled by integrating the POC-PEG/AgNW CPEs into a Bluetooth signal transmission system. Various human motions and physiological activities are successfully monitored using the wireless sensors. The results demonstrate that degradable citric acid-based polyester elastomers/AgNW CPEs are promising materials for next-generation sustainable and flexible electronic devices.
