Self-Healing Nanocomposites—Advancements and Aerospace Applications

Abstract: Self-healing polymers and nanocomposites form an important class of responsive materials. These materials have the capability to reversibly heal their damage. For aerospace applications, thermosets and thermoplastic polymers have been reinforced with nanocarbon nanoparticles for self-healing of structural damage. This review comprehends the use of self-healing nanocomposites in the aerospace sector. The self-healing behavior of the nanocomposites depends on factors such as microphase separation, matrix–nanofil… Show more

“…Obtained composites revealed a weak vibration peak around 550 cm -1 related to the presence of ZnO nanoparticles [23],while a prominent vibrational peak related to Ti-O mode appeared around 1380 cm -1 [24]. These TFA/DTA thermograms Figures (6)(7)(8)(9) showed several thermal stages with remarkable notes. Thermal decomposition of pure methylcellulose began degradation at 299 °C because of alkali -methylation influence on raw cellulose surface.…”

“…Self-healing can occur automatically through the interference of external stimuli, which is advantageous in various applications, including coatings, energy, electronics, and biomedical devices [28][29][30][31]. The self-healing process in the polymer matrix arises from the cumulative effect of chemical interaction [32], physical association [33], crosslinking [34], chain movement [35], and polymerization processes [36] (Figure 2). Subsequently, several factors influence the healing process of polymer matrices, including chain entanglement, chemical repair, and polymerization processes [30,31,[37][38][39].…”

“…Further understanding of the structure/property/processing relationship will enable more highly engineered functional components where repair is often preferred and more costeffective than replacement and therefore finds usage in biomedical, 21−23 soft robotics, 24−26 and aerospace applications. 27,28 ■ EXPERIMENTAL SECTION Materials. 2-Phenoxyethyl acrylate (POEA) containing 75−125 ppm of hydroquinone and 0−120 ppm of hydroquinone monomethyl as inhibitors, phenylbis (2,4,6-trimethylbenzoyl) phosphine oxide, commercially known as Irgacure-819 (BAPO), and 1,6-hexanediol dimethacrylate (HDDMA) containing 100 ppm of MEHQ were obtained from Sigma-Aldrich, USA.…”

“…Finally, the influence of varying PCL content on printed part dimensions was examined, and the ability to print detailed parts using the best performing self-healing resin system was demonstrated. Further understanding of the structure/property/processing relationship will enable more highly engineered functional components where repair is often preferred and more cost-effective than replacement and therefore finds usage in biomedical, soft robotics, and aerospace applications. , …”
