“…[168][169][170][171] On the other hand, there exist drawbacks 172 when manufacturing those exfoliated structures. An innovative nanocomposite discovered by Lau et al 173 could be an answer to this problem. The growth of nanotubes from nanoclay platelets provided a more robust reinforcement.…”

The incorporation of nanomaterials in the polymer matrix is considered to be a highly effective technique to improve the mechanical properties of resins. In this paper the effects of the addition of different nanoparticles such as single-walled CNT (SWCNT), double-walled CNT (DWCNT), multi-walled CNT (MWCNT), graphene, nanoclay and nanosilica on fracture toughness, strength and stiffness of the epoxy matrix have been reviewed. The Young's modulus (E), ultimate tensile strength (UTS), mode I (GIC) and mode II (GIIC) fracture toughness of the various nanocomposites at different nanoparticle loadings are compared. The review shows that, depending on the type of nanoparticles, the integration of the nanoparticles has a substantial effect on mode I and mode II fracture toughness, strength and stiffness. The critical factors such as maintaining a homogeneous dispersion and good adhesion between the matrix and the nanoparticles are highlighted. The effect of surface functionalization, its relevancy and toughening mechanism are also scrutinized and discussed. A large variety of data comprised of the mechanical properties of nanomaterial toughened composites reported to date has thus been compiled to facilitate the evolution of this emerging field, and the results are presented in maps showing the effect of nanoparticle loading on mode I fracture toughness, stiffness and strength.

“…The synergic effect of the CNT-clay hybrid as a filter resulted in a homogeneous dispersion and an improved interface, and therefore a strong interaction with the polymeric matrix. [128][129][130] For example, when only 1 wt % CNTs was used as filler, the improvement in the tensile modulus and the tensile strength were about 115 % and 120 %, respectively, compared with neat PA6, [131] but lower than when a CNT-clay hybrid was used.…”

Nanomaterials are shifting from laboratory-scale preparation to industrial production. The energy costs and starting materials (feedstock, catalyst, and support) consumed or used in the mass production of nanomaterials are issues that limit their broad application. Natural materials, such as sand, rock, and lava, contain small or trace amounts of metals or metal oxides of nanometer-scale sizes and have been recently used as catalysts for the production of carbon nanotubes (CNTs), providing an interesting way to lower the production cost of CNTs. However, the sustainability of the whole production process still needs to be explored. Layered minerals (e.g., clays) are used to produce CNT-clay hybrids, which can be further used to synthesize polymer-CNT-clay nanocomposites. Natural materials and some byproducts of industrial production processes have been explored as carbon sources for nanocarbon synthesis. This Minireview highlights some recent promising work and prospects for the use of natural materials in the synthesis of CNTs, carbon nanofibers (CNFs), and nanocomposites, and their applications in catalysis and in materials science.

“…Thus, CNTs must be firstly functionalized with carboxyl group before nonagglomerated fully introduced into ceramics matrix by heterogeneous nucleation technology. Similar process has been successfully applied to the uniform dispersion of other nanoparticles [7][8][9]. On the other hand, charged particles can improve the interfacial compatibility among different particles during composite powders preparation, which is also helpful for the preparation of composites and the improvement of interface strength between different phases in composites [9].…”
