Shape-memory and self-healing polyurethane-based solid polymer electrolytes constructed from polycaprolactone segment and disulfide metathesis

Recent advances in self-healing polyurethane based on dynamic covalent bonds combined with other self-healing methods

“…The reversible disulfide bond in the hard segment of PU leads to the self-healing ability, enhances the molecular chain's flexibility, and improves the elongation at the break of the material, but will relatively weaken the tensile strength. 46 The tensile strength and toughness of the structure can be increased with the addition of UPy units, but the elongation at the break can be decreased. As shown in Fig.…”

Self-healable, super Li-ion conductive, and flexible quasi-solid electrolyte for long-term safe lithium sulfur batteries

“…3C compares σ , n Li + and τ sh of the healed PAES-g-(PU/2PEG90) and PAES-g-(PUS/2PEG90) membranes with those of other recently reported self-healing electrolytes. 83–96…”

“…3C compares s, n Li + and s sh of the healed PAES-g-(PU/2PEG90) and PAES-g-(PUS/2PEG90) membranes with those of other recently reported self-healing electrolytes. [83][84][85][86][87][88][89][90][91][92][93][94][95][96] Effect of temperature. To investigate the Li + transport mechanism of the prepared membranes, the s of the original and self-healed PSEs was examined at various temperatures, as displayed in Fig.…”

Intrinsic Self-Healing Chemistry for Next-Generation Flexible Energy Storage Devices

“…However, polymer electrolytes without excellent fluidity are difficult to heal themselves when cracks and fractures caused by external forces such as stretching, twisting and bending [ 146 – 149 ]. The development of a flexible self-healing electrolyte capable of spontaneously repairing damage is essential to improve the electrochemical performance and reliability of energy storage devices [ 150 ].…”
