“…The growth of these nanostructures on the surface of the fibres has proven to be useful for increasing the interfacial adhesion between fibre and matrix, at least for synthetic fibres [57,58]. In literature there are very few studies investigating the effect of ZnO on natural fibres and specifically one is more focused on the antibacterial effect of ZnO on cellulose-based fibres [59] and the other is focused on the role that zinc oxides have in interfacial adhesion using poly (lactic acid) as a matrix [60]. Therefore, the ZnOs are of great interest both for the possibility of increasing the interfacial adhesion in composites but also for the ability to add new functionalities to natural fibres, such as antibacterial activity.…”

The ideal mechanical performance of a composite is controlled by the level of interfacial adhesion and to overcome the incompatibility issues between plant fibres and polymeric matrices, the surface of flax yarns has been modified by zinc oxide (ZnO) nanostructures. The ZnO nanorods were synthesized through a lowtemperature hydrothermal treatment, and several parameters have been analysed in order to obtain a uniform and homogeneous ZnO interphase, such as the number of the seeding cycles, the growth reaction times and the replacement of the growth solution. The results showed that it is possible to obtain highly oriented and well aligned ZnO nanostructures (by FE-SEM), with an hexagonal wurtzite structure (by XRD) and a high degree of coverage along the whole yarn (by TGA), reducing the number of the seed cycles, with rather long growth times (5 hours) and substituting the growth solution at least once during the synthesis. The experimental conditions preserved the breaking force of the yarns, while Single Fibre Fragmentation Tests (SFFT) highlighted a better interfacial adhesion of ZnO-modified flax yarns with epoxy matrix, which displayed a 29 % reduction in average debonding length relative to untreated yarns.

“…From Figure 4(b), it is evident that the addition of CuO and ZnO nanoparticles does not alter significantly the position of the tan d peaks located at approximately 71 C. The peak position for the unfilled KE was located at 72 C. The previous behavior supports the idea of poor interfacial interactions between these kinds of nanoparticles and the KE bio-composite, in agreement with other studies from the literature. 47,[68][69][70] By contrast, T g was shifted toward a higher temperature, showing maximum peaks at 83 C and 85 C for KE-GrO and KE-MK, respectively. The positive shift in the tan d peak position can be attributed to the physical interaction between the polymer and reinforcements that restrict the segmental chain motion in the KE bio-composites.…”

Ecological composites materials have become a topic of interest in materials science and engineering in recent years because of the growing need for environment-friendly composites that maintain properties like light weight, but gain biodegradability and renewability. Bio-composites of kenaf fiber-reinforced bio-based epoxy resin filled with different kind of nanoparticles were prepared in this work using a hybrid manufacturing process combining vacuum-assisted resin infusion and an autoclave. Nanoparticles of carbon, metal oxides and layered silicates were employed in this work to analyze their effect on the mechanical properties of bio-kenaf composites. Nanoparticles were synthesized and heat-treated according to their nature, and Fourier transform infrared spectra confirmed the presence of functional groups. Laminar structures, such as graphene or layered silicates, had more influence on the bio-kenaf composite toughness than the particle-like morphology of metal oxides. However, the nanoparticles influenced the strength because of their effective stress transfer mechanism. Despite voids of different sizes, which were detected using scanning tomography, they did not influence the mechanical properties of the bio-kenaf composites, showing that the filler effect of the nanoparticles is the dominant mechanism.

“…The deposition or growth of ZnO nanowires on natural fibres has been investigated in some studies. Yang et al (2020) modified sisal fibres with laterally grown ZnO nanowires to enhance the interface in poly (lactic acid) (PLA)/sisal biocomposites [ 66 ]. The deposition method was based on a two-step hydrothermal method with (i) dip-coating or immersion of sisal fibres in a seed suspension of ZnO colloidal particles and (ii) growth of unidirectional ZnO crystals from the seeded surface of sisal fibres ( Figure 9 c).…”

Several naturally occurring biological systems, such as bones, nacre or wood, display hierarchical architectures with a central role of the nanostructuration that allows reaching amazing properties such as high strength and toughness. Developing such architectures in man-made materials is highly challenging, and recent research relies on this concept of hierarchical structures to design high-performance composite materials. This review deals more specifically with the development of hierarchical fibres by the deposition of nano-objects at their surface to tailor the fibre/matrix interphase in (bio)composites. Fully synthetic hierarchical fibre reinforced composites are described, and the potential of hierarchical fibres is discussed for the development of sustainable biocomposite materials with enhanced structural performance. Based on various surface, microstructural and mechanical characterizations, this review highlights that nano-objects coated on natural fibres (carbon nanotubes, ZnO nanowires, nanocelluloses) can improve the load transfer and interfacial adhesion between the matrix and the fibres, and the resulting mechanical performances of biocomposites. Indeed, the surface topography of the fibres is modified with higher roughness and specific surface area, implying increased mechanical interlocking with the matrix. As a result, the interfacial shear strength (IFSS) between fibres and polymer matrices is enhanced, and failure mechanisms can be modified with a crack propagation occurring through a zig-zag path along interphases.
