“…[33,43] However, compared to nanotubes, relatively little work has been done to investigate the potential of 2D nanosheets as fillers in composite fibres. A number of papers have used chemically modified graphene (graphene oxide, GO) as a filler in composite fibres, [44][45][46][47][48][49][50][51][52][53] while other groups have studied graphene-oxide-only fibres. [54][55][56][57][58][59][60][61][62][63][64][65] However, while GO nanosheets may show good polymernanosheet stress transfer, they are not ideal reinforcements as they have impaired mechanical properties due to their high defect content (i.e.…”

Here we describe using nanosheets of both graphene and boron nitride, produced by liquid phase exfoliation, as fillers in composite fibres. The fibres were prepared by coagulation spinning using polyvinylalcohol as a matrix. We obtained good quality fibres with diameter and nanosheet volume fraction which could be controlled via the ratio of nanosheet to polymer injection rates. The mechanical stiffness (modulus, Y) and strength, σB, increased relatively slowly with volume fraction (dY/dVf 160 GPa and dσB/dVf 0.8 GPa). However, both stiffness and strength continued increasing with nanosheet content to loading levels of ~20vol%, after which the properties fell off. Such relatively high loading levels result in impressive mechanical properties with stiffness and strength of up to 30 GPa and 260 MPa observed. In addition, we found the graphene-filled fibres to be electrically conducting with conductivities of up to 3 S/m.

“…Novoselov et al [16] experimentally produced Single Layer Graphene (SLG) using scotch-tape method and a low cost method to synthesize graphene on large scale was presented by Stankovich et al [17] allowing the extension of the applications of graphene to industrial scale. After the groundbreaking experiments on the two-dimensional material graphene by Nobel Laureates, Sir Andre Geim and Konstantin Novoselov [16] from the University of Manchester, graphene came into limelight in research field mainly because of its excellent electrical [18], thermal [19], and mechanical properties [20]. Graphene found widespread applications in electronics [21], bio-electric sensors [22], energy technology [23], lithium batteries [24], aerospace [25], bio-engineering [26], and various other fields of nanotechnology [27].…”

Modeling and simulation allow methodical variation of material properties beyond the capacity of experimental methods. The polymers are one of the most commonly used matrices of choice for composites and have found applications in numerous fields. The stiff and fragile structure of monolithic polymers leads to the innate cracks to cause fracture and therefore the engineering applications of monolithic polymers, requiring robust damage tolerance and high fracture toughness, are not ubiquitous. In addition, when "many-parts" cling together to form polymers, a labyrinth of molecules results, which does not offer to electrons and phonons a smooth and continuous passageway. Therefore, the monolithic polymers are bad conductors of heat and electricity. However, it is well established that when polymers are embedded with suitable entities especially nano-fillers, such as metallic oxides, clays, carbon nanotubes, and other carbonaceous materials, their performance is propitiously improved. Among various additives, graphene has recently been employed as nano-filler to enhance mechanical, thermal, electrical, and functional properties of polymers. In this review, advances in the modeling and simulation of grapheme based polymer nanocomposites will be discussed in terms of graphene structure, topographical features, interfacial interactions, dispersion state, aspect ratio, weight fraction, and trade-off between variables and overall performance.

“…Few publications concern the use of Gr in textiles in the form of nanocomposites Tian et al 2014;Yuan et al 2014;Zhang et al 2013), as a yarn made from Gr flakes (Jalili et al 2013;Tian et al 2014) or using textiles as a support for Gr particles (Cheng et al 2013;Karimi et al 2015;Molina et al 2013a;Neves et al 2015) and are predominantly aimed at the potential applications of such materials in electronics. Rare applications of Gr for the modification of textiles can result from difficulties in its use in the form of aqueous dispersions.…”

Modification of cotton fabric with graphene and reduced graphene oxide using sol–gel method

et al. 2017

Cotton fabrics were modified by xerogel coatings with dispersed particles of graphene (Gr) or reduced graphene oxide (RGO). To obtain a stable dispersion of Gr or RGO in organo-silicon sol, sodium lauryl sulfate as an anionic surfactant was used. The fabrics were padded with the organo-silicon sol containing dispersed Gr or RGO, forming a thin xerogel coating after drying. The fabrics coated with the xerogel containing 0.5-1.5 wt% of RGO or Gr were prepared and examined. The best anti-static properties were obtained for the coating with 1.5 wt% of Gr, whose surface resistance and volume resistance were on the order of 10 5 and 10 3 X, respectively. Such properties make the fabric suitable for protective cloths in the environment with explosive atmosphere.
