“…During the last years, a few research papers related to the barrier properties of pristine graphene and PGNs have been reported, revealing enhanced barrier properties at lower loadings when compared to nano-clay composites. [ 87 , 88 ] Nanocomposites of crumpled GO functionalized with phenyl isocyanate in a polystyrene (PS) matrix, [ 87 ] exhibiting a high number of π -π interfacial interactions, showed exceptionally low permeability to oxygen at very low loading (0.02%) (similar permeability was obtained with nanoclays but at 1-1.5% loading). The AR and fi ller alignment also infl uence the gas permeation through a polymer composite.…”

Graphene constitutes a two dimensional sp2 hybridized carbon material with outstanding electrical and mechanical properties. To date, novel methods for producing large quantities of graphene and its derivatives (doped or functionalized graphenes, nanoribbons and nanoplatelets) are emerging, and research dedicated to the fabrication of polymer nanocomposites using graphenes has started. In this Research News, we summarize the synthesis and properties of graphene and its derivatives, and provide an overview of the latest research dedicated to the fabrication of polymer composites for different applications, including mechanical, electrical, optical and thermal. Some of the recently fabricated composites exhibit outstanding properties, however, it is vital to understand the chemistry and physics of the interphases established between the polymer and the graphene surfaces. The challenges in the fabrication of super robust and highly conducting composites using graphenes are also discussed. It is believed that graphene‐based polymer composites will result in commercial products if their interphases and reactivity are carefully controlled.

“…Aspect ratios have been measured in a number of the studies using various techniques. TEM was used in a couple of studies and values of 800 and 500 were reported [94,95]. These values are at least an order of magnitude higher than the aspect ratios reported from polymer-clay nanocomposites that were processed by melt blending [16,50,51], although more comparable to polymer/clay nanocomposites prepared by polymerisation and casting [56].…”

This paper reviews the literature on moisture barrier properties of polymer/clay and polymer/graphene-based nanocomposites. The various models proposed to predict the effects of nanofillers in reducing water vapour permeability through polymers are outlined. These models are based on a range of different factors such as; tortuosity, geometry, platelet stacking, orientation, polymer chain confinement and plasticization.Published experimental studies of water vapour permeability in both polymer/clay and polymer/graphene nanocomposites are then reviewed. The extent to which the models are validated by the results of these studies is discussed, together with the degree to which the potential for water barrier improvement in polymer nanocomposites has been realised.

“…Furthermore, as discovered by Bunch et al [91], graphene is impermeable not only to O2 but also to gas molecules as small as He. Not only high quality sheets but also crumpled graphene nanosheets have showed barrier potential when they were suspended in a polystyrene matrix [92]. The sheets effectively blocked the penetration of oxygen through the polymer-graphene mixture.…”

The near explosion of attention given to graphene has attracted many to its research field. As new studies and findings about graphene synthesis, properties, electronic quality control, and possible applications simultaneous burgeon in the scientific community, it is quite hard to grasp the breadth of graphene history. At this stage, graphene's many fascinating qualities have been amply reported and its potential for various electronic applications are increasing, pulling in ever more newcomers to the field of graphene. Thus it has become important as a community to have an equal understanding of how this material was discovered, why it is stirring up the scientific community and what sort of progress has been made and for what purposes. Since the first discovery, the hype has expediently led to near accomplishment of industrial-sized production of graphene. This review covers the progress and development of synthesis and transfer techniques with an emphasis on the most recent technique of chemical vapor deposition, and explores the potential applications of graphene that are made possible with the improved synthesis and transfer.
