For example, it use in nanocomposites, sollar cells, flexible electrodes for displays, electronic circuits, sensors [6].
Polymers based nanocomposites composed organic/inorganic fillers and polymers, where at least one material is in nanometer range [16].
Hexylamine, dodecylamine and octadecylamine were used respectively to investigate the effect of the grafted alkyl chain length on the physical properties of the PP/alkyl-GNP nanocomposites.
Characterization of the PP/Alkyl-GNP Nanocomposites
The PE/MWCNT nanocomposite was prepared by the onepot synthesis method using [Cp.sub.2]Zr[Cl.sub.2] in toluene followed by the activation with the MAO-adopting stirring method.

(iii) 2D nanocomposite coatings: the filler are nanolayers (1 dimension in nanometer scale).
Thus, there are 4 main groups of nanocomposite coating as follows (matrix/ nanofiller):
The [La.sub.2][O.sub.3]/GO nanocomposites were synthesized by using La[Cl.sub.3] x 7[H.sub.2]O and GO in DMF under reflux condition in one step.
TEM images of GL2 in Figure 2 showed the morphology of the [La.sub.2][O.sub.3]/GO nanocomposites. As shown in Figure 2(a), a few of the [La.sub.2][O.sub.3] nanoparticles were aggregated which could be also observed in SEM images.
In this study, the preparation of PVDF/clay nanocomposite membrane using organically modified clay by the blending method were investigated.
Nanocomposites are used in different applications, such as packaging, aerospace & defence, automotive, electronics & semiconductors, coating, and energy.
