Study on fabricating transparent, stretchable, and self-healing ionic conductive elastomers from biomass molecules through solvent-free synthesis

Abstract

Most of the known ionic electrical components are fabricated from petroleum-based raw materials and are not recyclable or degradable. A necessary solution involving the green fabrication of ionic conductors, which...

Simultaneously enhancing the mechanical robustness and conductivity of ionogels by in situ formation of coordination complexes as physical crosslinks

“…Our tough ionogels are positioned in the rightmost area of the plot, indicating that they possess superior fracture strength compared to the best-in-class conductive ionogel while maintaining competitive ionic conductivity. 26,30–37 This highlights the unique design and excellent properties of our ionogels.…”

“…28,29 Ionogels typically have low ionic conductivity due to strong intermolecular or intra-chain interactions. 30 However, in Fig. 4d, we compare the ionic conductivity and fracture stress of our metal coordination-toughened HAIM 41 -IL 4 –Ni 6 with other advanced conductive ionogels.…”

Solid-state, liquid-free ion-conducting elastomers: rising-star platforms for flexible intelligent devices

“…Another case is the incorporation of Al 3+ to strengthen the polyLA networks through coordination bonds for the construction of impressive stretchable and self-healing ionic conductive elastomers. 59…”

Wearable and Recyclable Water‐Toleration Sensor Derived from Lipoic Acid

“…Furthermore, the preparation of ionic liquids usually requires expensive components and, a complex fabrication process, and is harmful to the environment. [10] Deep eutectic solvent (DES) is recognized as a green solution consisting of a hydrogen bond acceptor (HBA) and hydrogen bond donor (HBD). DES has similar properties to ionic liquids and possesses the advantages of low cost, good biocompatibility, and green fabrication technique.…”

“…[18,[30][31][32][33][34] Recently, many researchers have successfully fabricated conductive elastomers based on LA. [10,24,25,[35][36][37][38][39] Despite the excellent transparency, ionic conductivity, and self-healing efficiency, most conductive elastomers suffer from a relatively low mechanical strength, especially stabilized LA by vinylic compounds. The metal ions (Fe 3+ and Al 3+ ) and double-network are hence introduced into the poly(LA) network, so as to construct multiple interactions (such as coordinate covalent bonding and hydrogen bonding) to improve the mechanics.…”
