Self-Healing Materials for Electronics Applications

Abstract

Self-healing materials have been attracting the attention of the scientists over the past few decades because of their effectiveness in detecting damage and their autonomic healing response. Self-healing materials are an evolving and intriguing field of study that could lead to a substantial increase in the lifespan of materials, improve the reliability of materials, increase product safety, and lower product replacement costs. Within the past few years, various autonomic and non-autonomic self-healing systems have been developed using various approaches for a variety of applications. The inclusion of appropriate functionalities into these materials by various chemistries has enhanced their repair mechanisms activated by crack formation. This review article summarizes various self-healing techniques that are currently being explored and the associated chemistries that are involved in the preparation of self-healing composite materials. This paper further surveys the electronic applications of self-healing materials in the fields of energy harvesting devices, energy storage devices, and sensors. We expect this article to provide the reader with a far deeper understanding of self-healing materials and their healing mechanisms in various electronics applications.

A review related to MXene preparation and its sensor arrays of electronic skins

“…The main types of non-covalent bonds are ionic interaction, hydrogen bonds and metal–ligand coordination bonds. 132 Yang et al 110 directly sprayed MXene solution onto PU on a heating table to create MXene-based flexible interdigital electrodes with a self-healing function. When PU/MXene was cut, the large number of hydrogen bonds on its surface directed the material to heal itself (Fig.…”

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

“…60,61 Application of PSEs and binders with high self-healing ability is expected to achieve signicant enhancement of the electrochemical performance of LSBs, because it can not only repair the interfacial cracks between the electrode/electrolyte, but also avoid the pulverization of the electrode active materials. [62][63][64] Although great progress in the development of self-healing materials has been made to date, their practical application in LSBs still faces enormous challenges. This is because it is quite difficult to design exible PSEs that afford both high self-healing efficiency and good electrochemical properties, such as ionic conductivity (s) and lithium transference number (n Li + ).…”

Molecular dynamics simulation insight into topological structure dependence of self-healing polymer nanocomposites

“…Nowadays, with the progress of science and technology, the development of various new materials is accelerated. Due to their ability to spontaneously repair damage, [1][2][3][4] self-healing materials have gained significant attention in the fields of life sciences, [4][5][6][7] bionics, [8][9][10] optical sciences, [11][12][13] semiconductors, 14 building materials [15][16][17] and light industries. [18][19][20] However, the majority of self-healing materials require the addition of fillers or agents to repair cracks or damages, 1,21,22 which limits their application.…”
