Hu, Xiao;Zhang, Runan;Wemyss, Alan M.;Elbanna, Mohamed A.;Heeley, Ellen L.;Arafa, Mustafa;Bowen, Chris;Wang, Shifeng;Geng, Xueyu;Wan, Chaoying research published 《 Tuning triboelectric and energy harvesting properties of dielectric elastomers via dynamic ionic crosslinks》, the research content is summarized as follows. The bromination of poly(isobutylene-co-isoprene) rubber introduces a small amount of bromide groups (1-2 mol%) to the elastomer backbone and creates new opportunities for functionalisation, as compared to other saturated and diene elastomers. In this work, three types of nucleophile reagents: namely pyridine, triphenylphosphine and imidazoles bearing four types of side groups of Me, Et, hydroxyl or vinyl group were introduced to brominated poly(isobutylene-co-isoprene) rubber (BIIR) through nucleophile substitution with the bromine via solid-state rubber compounding and curing processes. The resulted ionic aggregates act as phys. crosslinks and their size and d. directly affected the mech. reinforcement, self-healing and dynamic mech. properties of the elastomers. The smaller and polar imidazolyl/bromine pairs led to the highest reinforcement beyond even the sulfur-cured BIIR counterparts. The 1-Et imidazole (EIm) modified BIIR showed the highest tensile strength of 17.01 ± 1.89 MPa and elongation at break of 1402 ± 69% with self-healing efficiency of 63.7%, after being treated at 140°C for 30 min. In addition, the inclusion of the ionic clusters enhanced the relative permittivity of the elastomer, thereby enhancing the energy conversion efficiencies. The nucleophile substitution reaction via conventional solid-state rubber compounding processes provides a facile crosslinking and reinforcement strategy for halogen-containing polymers. In addition, the dynamic ionic crosslinking networks spontaneously benefit electromech. and self-healing properties of the dielec. elastomers.

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., Computed Properties of 1739-84-0
