“…2, the MWCNTs/NR-latex containing 24.00 mM TC14 exhibited the highest electrical conductivity. A comparison of the conductivity results for the series of SDS (mono-chain), AOT14 (di-chain) and TC14 (tri-chain) revealed a clear trend of increasing electrical conductivity with increasing number of tails, as reported previously [22,35,36]. However, a discrepancy in conductivity can be seen for TC14 systems with below cmc (21.63 mM) due to dynamic equilibrium behaviour of surfactant at MWCNT interface.…”

The performance of single-, double-and triple-chain anionic sulphosuccinate surfactants for dispersing multiwall carbon nanotubes (MWNCTs) in natural rubber latex (NR-latex) was studied using a range of techniques, including field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), thermogravimetric analysis (TGA) and Raman spectroscopy. The conductivities of the nanocomposites were also investigated using four-point probe measurements. Here, MWCNTs were efficiently dispersed in NR-latex with the aid of hyperbranched tri-chain sulphosuccinate anionic surfactants, specifically sodium 1,4-bis(neopentyloxy)-3-(neopentyloxycarbonyl)-1,4-dioxobutane-2-sulphonate (TC14). This paper highlights that TC14 performs much better than that of the commercially available surfactant sodium dodecyl sulphate (SDS), demonstrating how careful consideration of surfactant architecture leads to improved dispersibility of MWCNTs in NR-latex. The results should be of significant interest for improving nanowiring applications suitable for aerospace-based technology.

“…25 This remarkable reduction in surface tension is believed to be a direct consequence of increasing the CH3:CH2 ratio per headgroup (increase the branching using "hedgehog" tail structures), since the CH3-has a lower γcmc than -CH2-based on the following trend of CF3-< -CF2-< CH3-< -CH2-. 52 …”

“…In water, however, the hydrophobic nature of graphene leads to the agglomeration of graphene sheets into graphitic layered structures or agglomerates, thus spontaneous wetting by water is theoretically impossible. It has long been established in colloid science that to achieve a thermodynamically stable dispersion of one phase in another requires the lowering the interfacial energy between two immiscible phases, using surfactants that either strongly bind to the target compound or are solvated by the continuous phase [87][88][89]. However, very little is known as to whether graphene dispersions can be thermodynamically stable [90].…”

Graphene is the newest member of the carbon family, and has revolutionized materials science especially in the field of polymer nanocomposites. However, agglomeration and uniform dispersion remains an Achilles" heel (even an elephant in the room), hampering the optimization of this material for practical applications. Chemical functionalization of graphene can overcome these hurdles but is often rather disruptive to the extended piconjugation, altering the desired physical and electronic properties. Employing surfactants as stabilizing agents in latex technology circumvents the need for chemical modification allowing for the formation of nanocomposites with retained graphene properties. This article reviews the recent progress in the use of surfactants and polymers to prepare graphene/polymer nanocomposites via latex technology. Of special interest here are surfactant structure-performance relationships, as well as background on the roles surfactantgraphene interactions for promoting stabilization.
