Functional Polymer Nanocomposites with Graphene: A Review

Abstract

Polymer/graphene based nanomaterials have attracted significant scientific interest in the recent years due to marked enhancement in the polymer properties at low filler fractions. The property enhancements are attributed commonly to high aspect ratio of graphene platelets, filler-polymer interactions at the interface, as well as uniform dispersion of the platelets in the polymer matrices. Graphene also provides opportunities to tune its surface in order to achieve compatibility with the polymer matrices. Occasionally, chemical binding of the polymer matrix to the graphene surface has also been achieved.

A review of the water barrier properties of polymer/clay and polymer/graphene nanocomposites

“…Hence, exfoliation and a uniformly dispersed structure can be achieved [85][86][87][88]. Due to excellent barrier properties, graphene based nanocomposites have significant potential not only in packaging applications but also in sensitive electronic devices, such as organic light emitting diodes (OLEDSs) [89][90][91][92][93]. Figure 5 is a schematic diagram illustrating permeation through exfoliated graphene based nanocomposites.…”

The Role of Selectively Located Commercial Graphene Nanoplatelets in the Electrical Properties, Morphology, and Stability of EVA/LLDPE Blends

“…The number of possible applications and methods to produce graphene has witnessed an enormous expansion since its discovery, but the techniques to make high purity fully exfoliated graphene are not feasible for large‐scale fabrication . Mechanochemical exfoliation of graphite is a lower‐cost alternative to mass‐produce high aspect ratio graphene nanoplatelets (GN).…”

Dynamics of electric charge transport and determination of the percolation insulator-to-metal transition in polyvinyl-pyrrolidone/nano-graphene platelet composites

“…For example, water solutions PVP/ NGP composite can be used as bio-compatible link between electrodes and skin or tissues. As a result, various coated functional polymers with graphene [2, 3] have been prepared in order to analyse the mechanisms of charge transfer [4], to find the critical nanoparticle concentration to achieve percolation of electric charge carriers along the volume of the composite [5,6,7] and generally to inspect the electrical properties for those various matrices.Lastly, PVA (polyvinyl-alcohol) is a relevant material with polyvinyl-pyrrolidone that has been studied significantly [8]. In such studies, the dc conductivity vs composition is examined to find the percolation threshold.…”
