“…Owing to the good compatibility between ionic surfactants and carbon materials, this type of surfactant has been the main focus of investigations into graphene dispersions. Sodium dodecylsulfate (SDS), sodium dodecylbenzenesulfonate (SDBS), and cetyltrimethylammonium bromide (CTAB) are surfactants most frequently used to improve the dispersion of CNTs [96,97], and, more recently, graphene [60]. Also investigated was the use of bile salt biosurfactants (sodium cholate (SC) surfactants) [57].…”

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.

“…By adding pre-dispersed CNTs [19] to the aqueous film former, different CNT weight fractions within a GF coating can be adjusted. After the CNTs are homogenized within the polymeric film former they can be deposited onto the GF in a separate sizing or coating step.…”

ACCEPTED MANUSCRIPT AbstractIn this study, a new approach for health monitoring of GF reinforced composites is presented by incorporating percolated carbon nanotubes (CNTs) into the composites interphase. This is achieved applying CNT-filled coatings to glass fibres (GF). Taking advantage of the electrical properties of CNTs, this allows a highly localized monitoring of the composites interphase.The approach is largely independent on matrix material and can be applied to thermoplastic or thermoset resin matrix materials with minor adjustments. The resistance of CNT-coated GF yarns shows a linear dependence on the yarn length and depends on the CNT weight fraction of the coating, as well as on the amount of coating on the GF yarn. Performing tensile tests in combination with simultaneous resistance measurements on CNT-coated GF yarns embedded in a polypropylene matrix, the interphase behaviour during mechanical loading is monitored, providing information on this specific area. This allows relating interphase failure or GF breakage to the resistance data and demonstrates the potential of this approach for health monitoring of GF reinforced composites.

“…Processing aids can include substances providing anti-static properties and lowering the friction during spinning and textile processing. Besides conventional sizing formulations, recent studies report on the incorporation of nanoparticles into aqueous sizings or coatings for enhanced fibre matrix adhesion [11][12][13] or functionalisation of the interphase by creating diffusion barriers [14]. Moreover, nanoparticles, namely carbon nanotubes, have been used for interphasial strain sensing [15][16][17][18].…”

Abstract.Interface related mechanical properties of unidirectional continuous glass fibre (GF)/polypropylene (PP) composites made of commingled yarns have been systematically studied according to a three level, three-factor factorial design. The three systematically varied factors comprised different silane coupling agent and film former contents in GF sizings as well as a varying GF diameter. Besides the statistical evaluation of those main effects on the transverse tensile and compression shear strengths of the composites, interfacial shear strength measurements on model composites have been performed. The latter ones as well as the results of the dynamic mechanical thermal analysis support the statistical significance of sizing components, the sizing content on the GF, and GF diameter for the mechanical properties of the composites. This highlights the interplay of proper sizing formulation and reproducible GF-spinning conditions, as both affect the interfacial bonding of continuously reinforced GF/PP composites.
