“…On impact, the liquid droplet flattens to form a disc, the detailed shape of which is determined by the surface tension, density, viscosity, and velocity of the liquid droplet [72]. This method is facing new challenges when applying nanosized powder as feedstock to generate nanostructured coatings for antifouling and anticorrosion [73][74][75]. The main challenge is that individual nanoparticles cannot be thermally sprayed because of their low mass and the resultant inability to be carried in a moving gas stream and deposited on a substrate.…”

Engineered nanomaterials (ENMs) are catalyzing the Industry 4.0 euphoria in a significant way. One prime beneficiary of ENMs is the transportation industry (automotive, aerospace, rail car), where nanostructured multi-materials have ushered the path toward high-strength, ultra-impact-resistant, lightweight, and functionally graded engineered surfaces/components creation. The present paper aims to extrapolate much-needed ENMs knowledge from literature and its usage in the aviation industry, highlighting ENMs contribution to aviation state-of-the-art. Topics such as ENMs classification, manufacturing/synthesis methods, properties, and characteristics derived from their utilization and uniqueness are addressed. The discussion will lead to novel materials’ evolving need to protect aerospace surfaces from unfolding SARS-COVID-19 and other airborne pathogens of a lifetime challenge.

In this work, polyaniline nanorod adsorbed on reduced graphene oxide (P@G) hybrid filler was prepared via in situ polymerization of aniline monomer in the presence of reduced graphene oxide as template. Fourier transform infrared, X‐ray diffraction, field emission scanning electron microscopy, and high‐resolution transmission electron microscopy images revealed the formation of P@G hybrid. The P@G hybrid was dispersed in dichlorobenzene and then introduced into epoxy resin at different loadings. The epoxy nanocomposites containing 9 wt% P@G hybrids (E/P@G9) exhibited a maximum DC conductivity of 1.34 × 10−5 S/cm that is eight orders higher compared to pure epoxy. At 103 Hz, a dielectric constant (ε′) of 163 was attained for E/P@G9, nearly 34 times higher than pure epoxy. A percolation threshold of 4 vol% was observed for ε′. Dynamic mechanical studies showed that significant enhancement in storage modulus values were exhibited for 3 and 5 wt% of hybrids. The glass transition temperature showed a maximum shift of 10°C to higher temperatures at 3 wt% loading of P@G hybrids (E/P@G3). The tensile strength, Young's modulus, and impact strength of the E/P@G3 nanocomposites enhanced by 19.7, 72, and 12%, respectively. The thermal stability of the epoxy nanocomposites also enhanced with the addition of P@G hybrid.

“…[41][42][43] In this eld, we have recently demonstrated PANI-GO composites in epoxy coatings, which reveal a resistance of 2.70 Â 10 6 U cm 2 for 12% GO aer 192 h of immersion in brine, with suitable antifouling properties. 44 In such GO-modied polyaniline/epoxy coatings on low carbon steels, raising the concentration of GO in the paint does not slow down the corrosion rate because of the hydrophilicity of GO. However, some substances such as di-octyl phthalate and titanium dioxide graed to GO improve the paint quality.…”
