To prepare polymer/graphite nanocomposites, several strategies have been considered, including the three main processes as shown below ... 

Both tensile strength and Young s modulus have been shown to be strongly improved when polymer/graphite nanocomposites are yielded. Polyacrylonitrile/ graphite nanocomposites show a drastic increase in both tensile strength and the Young s modulus at rather low filler content.Actually, the material stiffness is substantially enhanced whatever the way of preparation in-situ polymeriza-... 

Shen et al. [75] measured the electrical conductivity of polyethylene/maleic anhydride-grafted polyethylene/graphite nanocomposites. Electrical conductivity and morphology were influenced by the polymer preparation method and could be explained in terms of percolation theory.

Polyamide 6/graphite nanocomposites with markedly low percolation threshold value were recently prepared using an in-situ polycondensation approach. Based on transmission electron microscopy (TEM) results, the thickness of EG filler incorporated in the polymer matrices was found to vary from 10 to 50 nm, and the aspect ratios (diameter to thickness) can be estimated as high as 100-300. The graphite used by Pan et al. is termed foliated graphite (FG). FG can... 

Graphene-polymer nanocomposites share with other nanocomposites the characteristic of remarkable improvements in properties and percolation thresholds at very low filler contents. Although the majority of research has focused on polymer nanocomposites based on layered materials of natural origin, such as an MMT type of layered silicate compounds or synthetic clay (layered double hydroxide), the electrical and thermal conductivity of clay minerals are quite poor [177]. To overcome these shortcomings, carbon-based nanofillers, such as CB, carbon nanotubes, carbon nanofibers, and graphite have been introduced to the preparation of polymer nanocomposites. Among these, carbon nanotubes have proven to be very effective as conductive fillers. An important drawback of them as nanofillers is their high production costs, which... 

In Situ Intercalative Polymerization A variety of polymer nanocomposites have been prepared using this method, that is, PS/graphene, PMMA/expanded graphite, poly(styrene sulfonate) (PSS)/layered double hydroxyl (LDH), PI/LDH, and PET/LDH. 

During the past decades, nanotechnology has attracted great attention due to its marvellous potential applications in numerous areas [90]. Polymer nanocomposite is a unique addition in the nanotechnology family. In polymer nanocomposite, one phase is dispersed in another phase in nanometer level [19]. Different types of reinforcing fillers such as sodium montmo-rillonite, sodium bentonite, layered double hydroxide, exfohated graphite, fullerene, carbon nanofiber, and carbon nanotube have been successfully used in the preparation of polymer nanocomposites [19]. Recently,...
