“…To assess the overall performance of these composites, the electrical and mechanical properties of these graphene based composites are compared with the results in literature as shown in Table 3 [20,32,36,[56][57][58][59]. It is demonstrated that among these surface modified graphene reinforced TPU composites, current study exhibits relative high conductivity with the same amount of filler content (1 wt.%).…”

“…In fiber reinforced polymer composites, the filler dispersion status and interfacial interaction between filler and matrix have crucial influence on their mechanical performance [32]. Therefore, above observed graphene surface modification due to oxidation, PVP coating and reduction should have obvious effect on the mechanical performance of these composites.…”

“…Especially for polar polymers, for example, polyurethane (PU) [12][13][14], poly(butylene terephthalate) [15], and epoxy resin [16,17], because some interactions would take place between oxygen-containing functional groups on the GO surface and polymer matrix. However, the application of GO in non-polar polymers is limited because they are incompatible.…”

Reducing and chemically functional modification of graphene oxide (GO) has attracted much attention in nanomaterial fields due to the outstanding properties of the graphene. In this article, water, a low cost and environmentally friendly reduction agent, to reduce selectively GO to form reduced GO (rGO) was applied, followed by modifying rGO with functional monomer octadecylamine (ODA), and subsequently polypropylene (PP) based nanocomposites containing functional graphene were fabricated via masterbatch-melt blending technique. The effects of reduction and functionalization on the microstructural and chemical-physical properties of GO were investigated comparatively by using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and X-ray photoelectron spectroscopy (XPS). The dispersibility of functional graphene before and after reduction was verified by using various agents. The experimental results showed that GO has been reduced selectively by water. Functional monomer ODA has been grated successfully on the surface of rGO and GO. The prepared graphene/PP nanocomposites were characterized by using Differential scanning calorimetric (DSC), XRD, scanning electron microscope (SEM), tensile, and impact tests. The results showed that the crystallization temperature (T c ) and melting temperature (T m ) of PP in the nanocomposites increased when the functional graphene was incorporated. The functional graphene has been dispersed uniformly in the PP matrix. Tensile tests showed that rG-ODA could improve the tensile strength and elastic modulus of composites more effectively than G-ODA. But G-ODA was more effectively in improving the toughness of PP than rG-

The high aspect ratio of nanoscale reinforcements enhances the tensile properties of a pure polymer matrix. Researchers have reported the morphology and tensile properties of thermoplastic polyurethane and halloysite nanotube (TPU-HNTs) nanocomposites, formed through compression moulding processes. Few researchers have reported on TPU-HNTs formed through injection moulding. Therefore, the present work investigates the tensile properties of TPU and HNT nanocomposites via injection moulding. TPU and HNTs were mixed using a brabender mixer with concentrations ranging from 1wt.% to 15wt.% and varying mixing parameters (i.e., mixing speed, mixing time, and mixing temperature). Tensile bars were injection moulded by varying the moulding parameters (i.e., injection temperature, injection time, and injection pressure). A significant increment of tensile strength was found at 1wt.% HNT reinforcement. TPU-HNT nanocomposite with 1wt.% reinforcement exhibited tensile strength of 24.3 MPa, which was higher than that of pure TPU. The Young's modulus of the TPU-15wt.% HNT nanocomposite was 21.5 MPa. Thus, TPU-HNT had improved mechanical properties, compared to pure TPU, due to the addition of a nanofiller.
