An adhesive, anti-freezing, and environment stable zwitterionic organohydrogel for flexible all-solid-state supercapacitor

Ultrahigh conductivity and antifreezing zwitterionic sulfobetaine hydrogel electrolyte for low-temperature resistance flexible supercapacitors

“…According to the zwitterionic groups of SBMA, 28,31,60 hydrophilic amide groups and hydroxyl groups of HEAA, 37 and Li + , they can interact with water molecules and can then hinder the formation of ice crystals. At −40 °C, the ionic conductivity of PSH 4–6/LiCl(6) reached up to 2.21 S m −1 , which was much higher than the 0.08 S m −1 for PHEAA /LiCl(6) and also surpassed that of previously reported values, such as 1.26 S m −1 for SBMA–HEA/LiCl and 0.28 S m −1 for PVA/P(SBMA-AM)/CaCl 2 at −40 °C; 32,61 detailed comparisons with more examples are shown in Table S3 †…”

Salt Transport in Crosslinked Hydrogel Membranes Containing Zwitterionic Sulfobetaine Methacrylate and Hydrophobic Phenyl Acrylate

“…However, this increase in Young’s modulus comes with a corresponding decrease in the strain at break. Notably, these SBMA-containing hydrogel membranes have a relatively high Young’s modulus compared to some other reported SBMA-containing membranes [ 35 , 36 , 37 ]. For instance, Shen et al reported crosslinked poly(SBMA) hydrogel membranes, using MBAA as the crosslinker analogous to our work here, to have a Young’s modulus of 0.002 MPa, and crosslinked copolymer hydrogels of SBMA with acrylic acid all had Young’s moduli under 0.4 MPa [ 35 ].…”

A high-thermopower ionic hydrogel for intelligent fire protection

“…This was because there were strong interactions (H bonds, ion-dipole interactions, cation-p interactions and electrostatic attractions) between the HTIG and the substrates (wood, PET, ABS, PU, PDMS and PMMA), and the polymer segments migrated to porous surfaces, making them more cohesive. 33,34 Additionally, the effect of the PDDA content on the HTIG adhesive performance was studied. With the increase of PDDA, the shear strength between the HTIG and wood was reduced (Fig.…”
