The preparation and application of polymer/graphene nanocomposites

Abstract

In recent years, polymer/graphene nanocomposites have attracted much attention because of their wide applications in many fields, such as chemistry, physics, materials and electronics. In this review, the preparation methods of polymer/graphene nanocomposites, including solution blending, melt blending and in situ polymerisation, were presented in order to study the relationship between these methods and their final properties. Each method has an influence on the final characteristics of the nanocomposites. Their respective advantages and disadvantages were discussed. Additionally, the potential application research of graphene-reinforced polymer nanocomposites, including supercapacitors, sensors and solar cells was detailed comprehensively. The current review demonstrated that the nanocomposites exhibit superior performances and will be applied as new materials or novel devices. The research direction of polymer/graphene nanocomposites in the future was also predicted.

High-tech graphene oxide reinforced conducting matrix nanocomposites—Current status and progress

Varying the degree of oxidation of graphite: effect of oxidation time and oxidant mass

“…1,2,[4][5][6] It has a large theoretical specific surface area (B2600 m 2 g À1 ), high intrinsic mobility (B200 000 cm 2 V À1 s À1 ), high Young's modulus (B1.0 TPa), thermal conductivity (B5000 W m À1 K À1 ), optical transmittance (B97.7%), and good electrical conductivity, [7][8][9][10][11] whereas it can be utilized for the development of polymer nanocomposites with superior properties that can be used in many different applications. 12,13 However, its poor solubility in a wide range of solvents 14,15 limits its further applications in many fields. On the other hand, the graphene's surface can be easily modified to graphene oxide by adding hydrophilic functional groups such as oxygen groups.…”

Investigation into the effects of foaming variables on the cellular structure and expansion ratio of foamed TPU using response surface methodology

“…Polymer foam is a unique multicomponent material, with dispersed or continuous gas phase in the polymer matrix. 10,11 The addition of gas not only reduces the consumption of raw materials, but also provides many advantages, including high elasticity, contaminant adsorption, 12 shock absorption, 13 heat insulation, sound insulation, and high strength/weight ratio. Therefore, it has been used in many industrial fields and daily life.…”
