Preparation of polyester resin/graphene oxide nanocomposite with improved mechanical strength

Abstract

Graphene oxide (GO) has attracted huge scientific interest due to its unique physical and chemical properties as well as its wide-scale applicability including facile synthesis and high yield. Here, we report preparation of nanocomposites based on GO and unsaturated polyester resin (PE). The synthesized samples were characterized by Fourier transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy, thermogravimetric analysis, and tensile strength measurements. A good dispersion of the GO sheets within the resin matrix was observed from the morphological analysis. A significant enhancement in mechanical properties of the PE/GO composites is obtained at low graphene loading. Around 76% improvement of tensile strength and 41% increase of Young's modulus of the composites are achieved at 3 wt % loading of GO. Thermal analysis of the composite showed a noticeable improvement in thermal stability in comparison to neat PE.

“…However, with the expanding use of furan resin, the continuous improvement of engineering quality requirements, its poor mechanical properties and some shortcomings gradually expose, thus limit its development. [20][21][22][23][24][25][26][27][28][29][30] To enhance the properties of the graphene based polymer composites, graphene must be exfoliated and dispersed in polymers well. [11][12][13][14][15] Graphene, a one-atom-thick 2D layer of sp 2 -bonded carbon, has been intensively studied since its discovery.…”

Effect of modified graphene and carbon nanotubes on the thermal properties and flammability of elastomeric materials

“…In recent years, there have been many published reports describing the physical properties of polymeric composites containing carbon nanofillers [23][24][25][26][27][28][29][30]. There is still a lack of systematic studies presenting the impact of this kind of fillers on the thermal properties and flammability of polymeric composites.…”
