“…Thus, before the implementation of latex compounding, surfactants, such as CTAB or sodium dodecyl sulfate (SDS), are introduced to assist the dispersion of CNTs or graphene [104][105][106][107]. Yang and coworkers employed SDS as a surfactant when mixing EG with NBR latex.…”

“…162 The percolation threshold is defined as the theoretical graphene fraction needed to obtain the first continuous graphene path through the polymer matrix. Conductivity undergoes an abrupt increase at this graphene content, and conductivity can therefore be used to define the percolation threshold.…”

“…162,168,169 For the latter parameter, the number of possible percolating paths decreases with increasing latex diameter, thus a lower percolation threshold is expected for larger latex beads. Moriarty et al 168 verified this effect using carbon black (CB)-filled composites.…”

International audienceThis review article describes recent advances in the elaboration of graphene-based colloidal nanocomposites by the use of graphene or graphene oxide in heterophase polymerization systems. Two main routes are reviewed: latex blending and in situ polymerization. In the first strategy, a segregated network is formed by confining the graphenic fillers in the interstices between the latex particles during the drying process. The morphology of the network depends on the relative dimensions of the fillers and the latex particles and on the interfacial interactions. The various approaches used to promote latex/graphene interactions via charge attractions or pi stacking are reviewed. The second method relies on the in situ formation of polymer latexes in the presence of graphenic fillers using emulsion, miniemulsion or suspension polymerization processes in the presence or absence of a stabilizer. The use of graphene oxide as a Pickering stabilizer and the effect of the dimensional characteristics of the graphene sheets on particle morphology are also discussed. Finally, a brief discussion of the mechanical and electrical properties of graphene-latex nanocomposites with regard to the characteristics of the filler and the latex-graphene relative dimensions is given to provide insight into the main requirements of graphenic fillers with respects to various applications

“…The electrical percolation threshold could be decreased by controlling the conductive network structure via different methods, such as shear [22,23], thermal annealing [24,25], polymer blending [26,27], synergistic effect of mixed fillers [28][29][30], latex particles or microspheres [31,32], etc. Among these methods, latex particles or microspheres are usually used to construct highly ordered three dimensional (3D) conductive graphene network in polymer matrix in recent years [33][34][35][36][37][38].…”
