“…Overall, mechanical properties of such composites have been found to increase linearly with increasing the nanofiller content. GOs have excellent thermal, mechanical and barrier properties [76,162] . In the presence of oxygen on their surfaces, GOs are soluble in water and can be well dispersed in polar media [76,162] .…”

“…Jose et al [135] indicated that OH-groups present on PVA/starch blends decreased with increasing the graphene loading due to the formation of hydrogen bonding between them. In addition, Raheel et al [162] reported that the presence of exfoliated structures for PVA/MMT/GO nanocomposites were good evidence of the compatibility and excellent dispersion of nanofillers within PVA matrices due to the presence of many oxygen contained groups on GO surfaces.

This review exclusively addresses material systems primarily based on poly (vinyl-alcohol) (PVA), one of the most popular water soluble biopolymers, for their use in packaging applications with the primary objective of reducing petro-based plastic waste. In addition, some typical PVA blends and nanocomposites are discussed as comparative studies for material packaging. Structural characteristics, mechanical, thermal and barrier properties, in addition to biodegradation of these multiple material systems, are summarised in a systematic manner.Finally, associated fabrication processing methods together with the most popular theoretical models used for the permeability of PVA nanocomposites are also reviewed in detail.

“…Single MMT layer consists of one aluminium octahedron sheet between two silicate tetrahedron sheets with the layer thickness of approximately 1 nm. MMT is compatible with water soluble polymers because of their hydrophilic characteristic [44,45]. Lilichenko et al [46] used MMTs to reinforce TPS.…”

“…Graphene has a 2-dimensional structure of sp 2 -hybridised carbon molecules in hexagonal lattice [79,80]. Due to the presence of oxygen on the surface, GO has the ability to be dissolved in water and other polar solvents [44]. Graphene and GO have a high surface area, mechanical, thermal and electrical properties like CNTs with less agglomeration problem [44,78,79].…”

Starch nanocomposites are popular and abundant materials in packaging sectors. The aim of this work is to review some of the most popular starch nanocomposite systems that have been used nowadays. Due to a wide range of applicable reinforcements, nanocomposite systems are investigated based on nanofiller type such as nanoclays, polysaccharides and carbonaceous nanofillers. Furthermore, the structures of starch and material preparation methods for their nanocomposites are also mentioned in this review. It is clearly presented that mechanical, thermal and barrier properties of plasticised starch can be improved with well dispersed nanofillers in starch nanocomposites.

This study investigated the synergistic effects of two different type of nanofillers, that is, halloysite nanotube (HNT) and montmorillonite (MMT) on anticorrosion performance and flame retardancy properties of graphene oxide reinforced epoxy coatings for structural steel application. Electrochemical impedance spectroscopy (EIS), Tafel polarization, salt spray test (SST) and limiting oxygen index (LOI) tests were conducted to reveal the effects of hybrid nanofillers on corrosion protection and flame retardancy performance of the coatings. The dispersion of the nanofillers with the matrix was characterized via transmission electron microscopy (TEM). The results showed, EGO0.6 coatings exhibited the best anticorrosion performance (Rct = 2.105 × 109 Ω.cm) compared to E0 coating (Rct = 6.420 × 108 Ω.cm) and epoxy filled with single nanofiller. The coating reinforced with hybrid nanofillers, EGO0.6H0.3 showed further improvement in corrosion resistance, compared to other single and hybrid nanofillers coatings studied. All epoxy coating samples filled with nanofillers showed slow burning behavior in the LOI test. The incorporation of hybrid nanofillers increased the LOI value of EGO0.6H0.4 coating up to 25.0 from 21.0 for neat epoxy coating. The LOI data shows a good correlation with char formation from thermogravimetric analysis analysis. TEM results revealed a positive effect of the nanofillers on HNT/GO/epoxy coating showing a well‐dispersed and enhanced barrier properties.
