“…A parallel approach, but with a different polymer, was undertaken by Matos et al [44], here TEM elemental mapping of nitrogen was used to show that CTAB adhered preferentially at the edges of the rGO sheets and coalesced rubber. The ability of surfactants to alter interfacial energy is one of the driving forces for the migration towards the interface during film formation [114]. This characteristic was proposed to be an important factor for the interaction between filler and polymer matrix.…”

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.

“…Zhao and co-workers (18,19) have shown by XPS, SIMS, and FTIR-ATR that films from MMA-BMA latexes prepared using the same surfactant as in the present work (sodium dodecyl diphenylether disulfonate, SDED) or sodium dodecyl sulfate (SDS) have different behaviors: in the case of SDS, they observed an enrichment of surfactant at the film-air and filmsubstrate interfaces during the film maturation. This is expected because the surface active agents lower the interfacial tension at the polymer/air and polymer/substrate interfaces.…”

“…This incompatibility likely results in their migration to the polymer surface [20,21]. In the case of emulsion PSAs, the enrichment of the surface by the surfactants creates a weak boundary layer when the PSA layer is applied to an adherend and, thus, results in a decrease of adhesion properties [22][23][24][25]. Therefore, it is necessary to analyze the surfactants distribution in the composite PSA.…”

2004) Acrylic emulsion pressure-sensitive adhesives (PSAS) reinforced with layered silicate, Abstract-Composite acrylic pressure-sensitive adhesives (PSAs) were synthesized by emulsion polymerization in the presence of montmorillonite (MMT). An examination with X-ray diffraction (XRD) and transmission electron microscopy (TEM) showed that both intercalated and exfoliated structures of MMT coexisted in the composites. It was demonstrated by X-ray photoelectron spectroscopy (XPS) that enrichment of the surface by the surfactant during drying of emulsion PSAs was depressed by the layered silicate. Significant improvements in storage modulus and cohesive strength were achieved by incorporation of MMT. The addition of only a small amount of MMT was enough to improve the adhesion properties of acrylic emulsion PSAs.
