Recent progress in Epoxy Nanocomposites: Corrosion, structural, flame retardancy and applications — A comprehensive review

Abstract

In the past few years, epoxy resins utilization has gained much significant recognition from researchers worldwide as a result of its advantages in different sectors such as automotive, aerospace, electronic systems, constructions, and other related fields because of its outstanding mechanical performance, corrosion protection, and dielectric properties. The nanomaterials incorporation into the matrix has been duly examined to be the most productive route to enhance polymer composite's mechanical properties. Despite that, the inherent brittleness, relatively low fracture toughness, cross‐linking ability, poor electrical, and thermal properties of epoxy render it weak to growth and initiation of cracks, limiting its utilization in state‐of‐the‐art structural applications. Especially, epoxy is flammable while releasing a considerable amount of gases and smoke, thus, extending a potential risk to lives. Consequently, several nanofiller materials like graphene (Gr), transition metal dichalcogenides, MXene, and hexagonal boron nitride (h‐BN) produce extensive chances to equip multi‐functional characteristics and then reinforce the epoxy resins for the state‐of‐the‐art application. With this current review, the present literature investigation of epoxy filled with nano‐sized material has been examined thoroughly. Current advances in the approach of integrating nanosized materials in the epoxy matrices have been also introduced. Most significantly, anti‐corrosion, mechanical, and flame‐retardant properties of nanomaterials reinforced epoxy nanocomposites have also been reviewed in particular. Ultimately, the present statuses of the field in addition to the future approach have been considered concerning the usefulness of numerous nanofillers toward reinforcement of epoxy in construction and building materials. The expectation in this extensive review could produce a valuable reference, ingenuity, and guidance for researchers in this area of study.

In situ growth of Ag nanoparticles on the surface of MXene by γ-ray irradiation to fabricate EVA composite: the improvement of flame retardancy, smoke suppression, and mechanical properties

“…This promoted the formation of a thermal insulation carbon layer, serving as the second line of defense for the flame retardancy of the EVA/e-MXene@Ag1.0 composite. This condensed flame retardant thermal insulation layer exhibited the most prominent flame retardant effect [46].…”

Effect of hygrothermal aging on novel hybrid composites: Transforming textile waste into a valuable product

“…28 The processed specimens were taken from the hot water bathtub at regular intervals and their respective weights were calculated with the electronic weighing machine, by doing this, their corresponding F I G U R E 2 Fabricated hybrid composite laminates with varying graphene oxide (0%, 1%, 3%, 5%, 7%, and 9%). weight gain was calculated with the help of the formula mentioned in Equation (1).…”

“…Weight-to-strength ratio, chemical and corrosion resistance, easy processability, and exceptional insulation properties facilitate fiber-reinforced polymer matrix composites as the superior element in most applications like aerospace, marine, automotive, and structural usages. 1 Fiberreinforced polymer composites are an advanced material, their moisture absorption behavior has been considered one of the main drawbacks in most applications. Therefore, notable research has emphasized identifying the suitable matrix, reinforcements, and their corresponding characterization for hygrothermal aging environments.…”

Preparation of a novel SiO2/PMMA nanocomposite with high transparency, thermal stability, and superior surface hardness via gamma‐radiation polymerization

“…A successful combination of these materials can lead to improved performance and new functionalities that cannot be achieved by either component alone. Hybrid nanocomposites can manipulate characteristics such as mechanical strength, thermal stability, flame retardancy, electrical conductivity, and optical properties compared to pure polymers by adjusting the type, size, shape, and concentration of nanoparticles according to application requirements 1–4 . Researchers employ various techniques such as solution blending, melt mixing, and in situ polymerization to ensure adequate distribution of nanoparticle within the polymer matrix 5–7 .…”
