Polymer composites for structural applications are prone to damage emanating from cracks which are formed within the material, where detection is not easy and repairing almost not feasible. Material cracking results in mechanical deterioration of polymer composites for microelectronic components, which can result in electrical failure. Microcracking occurring as a result of thermally and mechanically induced fatigue is challenging for effective polymer performance. Self-healing composites are materials exhibiting capability of automatically recovering when damaged. They derive their inspiration through biological systems similar to the human skin, which exhibit a natural tendency to undergo healing by themselves. Stretchability is a factor enabling electronic devices to properly align to irregular 3-D structures, such as soft and movable parts. Stretchable electronics offers materials with the ability to conform to soft and nonplanar composites while enabling movement of biological tissues. Therefore, this article elucidates very recently emerging advancements on self-healing composites, stretchable composites, and sensors. Future market disposition and application of self-healing composites are also presented.

“…PP are composed of orthophosphate monomers bound together as result of phosphate condensation 11 , leading to chain lengths varying from a few units up to hundreds of phosphate units. Considering also that PP can make gels and arrested states in presence of Al 3+ due to strong phosphate-aluminium bond formation 12,13 , we propose that addition of PP can lead to arrested phases of clay particles by binding to multi-valent cations exposed at the particle edges. To test this hypothesis, we used aqueous dispersions of Laponite RD (LRD), from BYK.…”
Long-chain polyphosphates can bridge clay particles leading to new arrested systems: all-inorganic aqueous Wigner glasses. These materials may have use in agriculture and health sciences.
A multifunctional soft material with high ionic and electrical conductivity, combined with high mechanical properties and the ability to change shape can enable bioinspired responsive devices and systems. The incorporation of all these characteristics in a single material is very challenging, as the improvement of one property tends to reduce other properties. Here, a nanocomposite film based on charged, high‐aspect‐ratio 1D flexible nanocellulose fibrils, and 2D Ti3C2Tx MXene is presented. The self‐assembly process results in a stratified structure with the nanoparticles aligned in‐plane, providing high ionotronic conductivity and mechanical strength, as well as large water uptake. In hydrogel form with 20 wt% liquid, the electrical conductivity is over 200 S cm−1 and the in‐plane tensile strength is close to 100 MPa. This multifunctional performance results from the uniquely layered composite structure at nano‐ and mesoscales. A new type of electrical soft actuator is assembled where voltage as low as ±1 V resulted in osmotic effects and giant reversible out‐of‐plane swelling, reaching 85% strain.
