“…When the polymer or pre-polymer adsorbs onto the delaminated sheets, the solvent is evaporated and a sandwiched nanocomposites is formed (Kuilla et al, 2010). As mentioned, this method is rarely used for the preparation of thermoplastic polymer/graphene nanocomposites, only PP/graphene nanocomposite is reported recently (increased electric conductivity (Kalaitzidou et al, 2007)). In the melt intercalation technique, no solvent is required and graphite or graphene or modified graphene is mixed with the polymer matrix in the molten state (Kuilla et al, 2010), e.g.…”

“…Nanomaterials reinforced thermoplastic nanocomposites have shown significant growth, as research on the development of novel reinforcing methods intensified. Several methods such as melt blending, solution mixing, coating (Kalaitzidou et al, 2010), in-situ polymerization (Alexandre &Dubois, 2000), nanoinfusion, etc (Lentz et al 2010) are reported in the literature mostly aiming on the dispersability of the nanomaterials. The nanocomposites prepared using the above mentioned methods has a huge potential for applications in automotive (seat frames, battery trays, bumper beams, load floors, front ends, valve covers, rocker panels and under engine covers, etc) (Garces et al, 2000), aerospace (missile and aircraft stabiliser fins, wing ribs and panels, fuselage wall linings and overhead storage compartments, ducting, fasteners, engine housings and helicopter fairings,etc) (Zhao et al, 2010), optical devices (Ritzhaupt-Kleissl et al, 2006), electrical and actuator devices (Koerner et al, 2004), and as flame retardant.…”

“…For example, Kalaitzidou et al 90 have demonstrated that initial coating of the polymer particles by the nanocarbon using sonication in a solvent provides an improved melt intercalated product, in this case polypropylene reinforced with exfoliated graphite nanoplatelets. Zhan et al 87 compared the rGOrubber composite prepared by solution mixing and melt intercalation.…”

Graphene, a nanocarbon with exceptional physical and electronic properties, has the potential to be utilized in a myriad of applications and devices. However, this will only be achieved if scalable, processable forms of graphene are developed along with ways to fabricate these forms into material structures and devices. In this review, we provide a comprehensive overview of the chemistries suitable for the development of aqueous and organic solvent graphene dispersions and their use for the preparation of a variety of polymer composites, materials useful for the fabrication of graphene-containing structures and devices. Fabrication of the processable graphene dispersions or composites by printing (inkjet and extrusion) or spinning methods (wet) is reviewed. The preparation and fabrication of liquid crystalline graphene oxide dispersions whose unique rheologies allow the creation of graphene-containing structures by a wide range of industrially scalable fabrication techniques such as spinning (wet and dry), printing (ink-jet and extrusion) and coating (spray and electrospray) is also reviewed.

“…There have been numerous studies that have demonstrated that, the use of conductive nanofillers like carbon nanotubes (CNTs), carbon nanofibres (CNFs) or nanographite can improve the mechanical properties of epoxy resins and their composites [1][2][3][4][5]. Also the electrical conductivity of polymers containing organic nanofillers can be further improved [6][7][8][9][10] since only a small fraction of nanotubes or nanographite is needed to form the percolation conductive network.…”

Abstract. In this work, the effect of the inclusion of electrically conductive and non-conductive nanofillers in a state of the art epoxy gelcoat was studied. The conductive fillers used were multi-wall carbon nanotubes and exfoliated nanographite. The non-conductive ones were nanoclay and nano-titanium dioxide. The content of the nanofillers was 0.65% per weight and their inclusion took place using high shear mixing devices. The conductive fillers showed an increase in tensile and fracture properties, as well as in the thermal properties whereas the non-conductive fillers did not show any improvement on the fracture properties. The glass transition temperature was practically unaffected by the presence of the nanofillers while conversly, the coefficient of thermal expansion was decreased for all the nanofillers for temperatures above the glass transition temperature. Finally, weatherometer tests showed that the nanofillers contribute into less weight losses in comparison with the reference epoxy gelcoat.
