“…Dry et al expanded the work on hollow fibers to develop a three-part fiber system throughout the 1990s. [19][20][21] White et al, in 2001, developed a novel encapsulation approach that led to self-healing polymerbased systems and was highly investigated over the past 20 years as shown in Figure 3. [22,23] Instead of hollow fibers, the healing agents were embedded into microcapsules within the polymer composites allowing for many healing sites rather than the single hollow fiber.…”

The search for materials with better performance, longer service life, lower environmental impact, and lower overall cost is at the forefront of polymer science and material engineering. This has led to the development of self‐healing polymers with a range of healing mechanisms including capsular‐based, vascular, and intrinsic self‐healing polymers. The development of self‐healable systems has been inspired by the healing of biological systems such as skin wound healing and broken bone reconstruction. The goal of using self‐healing polymers in various applications is to extend the service life of polymers without the need for replacement or human intervention especially in restricted access areas such as underwater/underground piping where inspection, intervention, and maintenance are very difficult. Through an industrial and scholarly lens, this paper provides: a) an overview of self‐healing polymers; b) classification of different self‐healing polymers and polymer‐based composites; c) mechanical, thermal, and electrical analysis characterization; d) applications in coating, composites, and electronics; e) modeling and simulation; and f) recent development in the past 20 years. This review highlights the importance of healable polymers for an economically and environmentally sustainable future, the most recent advances in the field, and current limitations in fabrication, manufacturing, and performance.

“…Complete filling of healing agent into the tiny tubes was achieved by vacuum assisted capillary action filling technique. Accordingly, three types of healing system were developed ( Figure 2) [32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48]. (i) Single-part adhesive.…”

Abstract. Formation of microcracks is a critical problem in polymers and polymer composites during their service in structural applications. Development and coalescence of microcracks would bring about catastrophic failure of the materials and then reduce their lifetimes. Therefore, early sensing, diagnosis and repair of microcracks become necessary for removing the latent perils. In this context, the materials possessing self-healing function are ideal for long-term operation. Self-repairing polymers and polymer composites have attracted increasing research interests. Attempts have been made to develop solutions in this field. The present article reviews state-of-art of the achievements on the topic. According to the ways of healing, the smart materials are classified into two categories: (i) intrinsic self-healing ones that are able to heal cracks by the polymers themselves, and (ii) extrinsic in which healing agent has to be pre-embedded. The advances in this field show that selection and optimization of proper repair mechanisms are prerequisites for high healing efficiency. It is a challenging job to either invent new polymers with inherent crack repair capability or integrate existing materials with novel healing system.

“…Earlier generations of composites with resin filled fibres were reported by Dry et al [120][121][122][123] and Motuku et al 124 to rupture in response to damage and adequately release healing agent. The quality of healing, however, was limited by poor healing agent reactivity and especially large fibre sizes that frequently acted as initiation sites for failure.…”

Inspired by the unique and efficient wound healing processes in biological systems, several approaches to develop synthetic polymers that can repair themselves with complete, or nearly complete, autonomy have recently been developed. This review aims to survey the rapidly expanding field of self-healing polymers by reviewing the major successful autonomic repairing mechanisms developed over the last decade. Additionally, we discuss several issues related to transferring these self-healing technologies from the laboratory to real applications, such as virgin polymer property changes as a result of the added healing functionality, healing in thin films v. bulk polymers, and healing in the presence of structural reinforcements.
