An autonomously ultrafast self-healing, highly colourless, tear-resistant and compliant elastomer tailored for transparent electromagnetic interference shielding films integrated in flexible and optical electronics

Abstract

Considering the operation reliability of flexible and optical electronics (FOEs) in dynamic and real-world environments, autonomous self-healing electromagnetic interference (EMI) shielding materials with high transparency, good stretchability and excellent tear-resistance...

A high‐performance self‐healing polyurea material based on exchangeable aromatic disulfide

“…In addition, the toughness of SPUs was calculated based on the integral areas under stress–strain curve (Figure 6b). 22 The prepared SPU samples have remarkable toughness, especially the SPU‐4 sample, which has a high toughness value of 139.7 MJ·m −3 . This can be attributed to the dynamic properties of SS and hydrogen bonds, which can continuously break and rebuild during the stretching process to dissipate strain energy.…”

Facile and fast preparation of a tung oil-based bendable transparent electrode with mechanical strength and environmental stability via infiltration of silver nanowires into oxygen-inhibited surface layers

“…The N 1s peak shows two categories of N bonds, the OC–N bond at 399.8 eV and the hydrogen bond at 400.8 eV, further confirming the contribution of hydrogen bonds. 56…”

“…The N 1s peak shows two categories of N bonds, the O]C-N bond at 399.8 eV and the hydrogen bond at 400.8 eV, further conrming the contribution of hydrogen bonds. 56 We investigated topology network rearrangements of PAMET0 and PAMET1.25 by stress relaxation analysis at 5% tensile strain. According to the Maxwell relaxation model, the relaxation time (s) is dened as the time required for the modulus (G) to go down to 1/e of the initial modulus (G 0 ).…”

Rapid self-healing and tough polyurethane based on the synergy of multi-level hydrogen and disulfide bonds for healing propellant microcracks

“…Unfortunately, it has become its biggest failure that the polymer elastomer needed to be heat-treated at 100 1C for 36 h to be fully restored. Fu et al 43 adopted the self-assembly of different hard segment structures to design a super-fast self-healing, high colorless, tear-resistant, and compliant elastomer. It was conspicuous enough to complete self-healing within 100 s. However, their mechanical properties (maximum tensile strength) can only reach 0.25 MPa, which was not suitable for the situation where high mechanical strength was required.…”
