M.;Vancaeyzeele, Cedric;Vidal, Frederic;Plesse, Cedric;Wan, Chaoying research published 《 Tailoring Electromechanical Properties of Natural Rubber Vitrimers by Cross-Linkers》, the research content is summarized as follows. The growing demand for smart polymeric transducers such as dielec. elastomer actuators and energy harvesters has urged the use of sustainable and recyclable elastomeric materials. Vitrimer chem. has shed light on future reprocessable and recyclable thermosets and elastomers. In this work, epoxidized natural rubber (ENR) vitrimers were prepared using diacid or triacid crosslinkers and formed covalently crosslinking networks via thermally triggered reversible β-hydroxy ester bonds. The crosslinked ENR elastomers exhibited Arrhenius-type viscoelastic behavior with a complete stress relaxation between 140 and 160°C, i.e., vitrimer characteristics, which were highly dependent on the crosslinking temperature The mech. and dielec. properties of the ENR vitrimers can be tuned by varying the mol. structure and concentration of the crosslinkers. Among the diacid and triacid crosslinkers, Pripol 1017 fatty polyacid (P1017) and 3,3′-dithiopropionic acid (DTPA) had similar effects on the crosslinking d. and mech. properties of the ENR vitrimers. The highest tensile strength of 8.70 ± 1.9 or 15.6 ± 2.6 MPa was obtained at 6 mol % of P1017 or DTPA, resp. While for diamide-based diacid crosslinker (DME), 8 mol % was needed to reach the highest tensile strength of 13.1 ± 2.7 MPa for the elastomer. The three ENR vitrimers showed increased relative permittivity ε’ = 5~7 at 1 kHz while maintaining low dielec. losses compared to traditional dicumyl peroxide-cured ENR, with ε’ = 3.57 at 1 kHz. With the optimized acidic crosslinker concentrations of P1017 at 6 mol %, DTPA at 6 mol %, and DME at 8 mol %, the ENR vitrimers exhibited improved actuation capabilities at lower elec. fields. Utilizing dynamic crosslinkers to tune the electromech. properties of dielec. elastomers and the reversibly crosslinked polymer networks will open new opportunities for smart and sustainable dielec. elastomer devices.
1739-84-0, 1,2-Dimethylimidazole is used in the synthesis of 1,2-dimethyl-3-n-butylimidazoliumchloride and 1,2-dimethyl-3-n-propylimidazolium chloride. It also can be used in the synthesis of 1-(2-methoxyethyl)-2,3-dimethylimidazolium chloride and hexafluorophosphate salts.
1,2-Dimethylimidazole is a heterocyclic compound that contains nitrogen and carbon. It can be produced by the reaction between glyoxal and fatty acid in the presence of a base. 1,2-Dimethylimidazole has been shown to have biological properties such as an antioxidant effect. It is also used as a chemical intermediate for production of other chemicals such as 2-methylimidazole and 3-methylimidazole. 1,2-Dimethylimidazole has been shown to react with metal carbonyls to produce methylimines, which are useful intermediates in organic synthesis. The reaction mechanism involves hydrogen bonding and steric interactions between the imidazole ring and the metal carbonyl reactant., Application of C5H8N2
