“…The spectrum shows absorption bands at 1055 cm −1 (C―O), 1236 cm −1 (C―O―C), 1404 cm −1 (C―OH), and 1726 cm −1 (CO), which correspond well to the reported spectra of GO in the literature . It was these oxygenated functional groups that provided the possibility of in situ polymerization between polyimide and GO . So, the GO is directly bonded to the PI polymer matrix after polymerization.…”

Graphene oxide (GO) with different oxidation degrees were synthesized by harsh oxidation of graphite using the improved Hummers method. The GO/polyimide (PI) mixed matrix membrane was successfully fabricated by in situ polymerization of PI monomers (3,3′,4,4′-biphenyltetracarboxylic dianhydride and 4,4′-diaminodiphenyl ether) with GO. The structure of GO was characterized by Fourier transform infrared, transmission electron microscopy, atomic force microscopy, X-ray diffraction, and thermal gravimetric analysis-differential thermal analysis. The performance of different GO/PI mixed matrix membranes was evaluated by permeation experiments of CO 2 /N 2 gas mixture (volume ratio, 1:9). Results showed that more polar functional groups were introduced to GO with the increase in oxidation degree of GO in the preparation process, producing fewer layers and more translucent structures. GO with higher oxidation degree has significant effect on its dispersion in the N,N-dimethylacetamide solvent and polymer matrix materials. The permeability of GO/PI hybrid membranes for CO 2 and N 2 increased. The CO 2 /N 2 permeation selectivity of membranes exhibited a trend of initial increase, followed by a decrease, with the increase in oxidation degree, when the same amount of GO was added. For GO with the same oxidation degree, the permeability and permeation selectivity of hybrid membrane initially increased, and then decreased with the addition content of GO. In the case of hybrid membrane containing 1 wt% monolayer GO, the maximum permeability and permeation selectivity of hybrid membranes for CO 2 were 14.3 and 4.2 times more than that of PI membrane without GO, respectively.

“…The D / G ratios of GO, PNIPAM/KGM/GO1, PNIPAM/KGM/GO2, and PNIPAM/KGM/GO3 were 0.80, 0.82, 0.84, and 0.85, respectively (Figures 2(b)-2(e)). This change suggested that some oxygen functional groups in GO participated in the cross-linking process and were dehydrated, and the C=C bonds were partially restored, resulting in the increase in D / G [44]. Figure 3 shows the XRD patterns of GO (Figure 3(a)), PNIPAM/KGM/GO1 (Figure 3(b)), PNIPAM/KGM/GO2 (Figure 3(c)), and PNIPAM/KGM/GO3 (Figure 3 where GO showed a diffraction peak at 2 = 9.7 ∘ with ca.…”

Temperature-sensitive poly(N-isopropylacrylamide)/konjac glucomannan/graphene oxide (PNIPAM/KGM/GO) composite membranes were prepared by solution blending using calcium ions as a cross-linker. The composite membranes were characterized by Fourier-transform infrared spectroscopy (FT-IR), field-emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), Raman spectroscopy (Raman), and differential scanning calorimetry (DSC). The swelling, mechanical property, phase transformation behaviors, and enzymatic degradation activities were also determined. Results revealed that the phase transition temperatures of all the composite membranes were approximately 35°C. The PNIPAM/KGM/GO composite membranes showed enhanced mechanical property. The swelling behavior and enzymatic degradation of the PNIPAM/KGM/GO composite membranes improved compared with those of conventional PNIPAM hydrogel and PNIPAM/KGM composite membranes. Thus, the PNIPAM/KGM/GO composite membranes have potential applications in the biomedical field as skin dressings.

“…Recently, GO has emerged as one of the most attractive nanofiller in polymer nanocomposite technology due to the notable improvement and enhancement of mechanical, thermal, and electrical properties of many nanocomposites, improvements that could lead to innovative solutions for many applications (Zhu et al, 2010;Go´mez-Navarro et al, 2007;Liu et al, 2009;Dikin et al, 2007;Lei et al, 2012;Sun et al, 2008;Marcano et al, 2010;Satti et al, 2010;Park et al, 2009;Venugopal et al, 2012;Hu et al, 2010;Zinadini et al, 2014;Jin et al, 2015;Gudarzi and Sharif, 2012;Dreyer et al, 2010;Compton et al, 2012). For instance, in water filtration applications, GO could potentially solve the serious obstacle of polymer membrane fouling by biological species.…”

This paper expresses a short review of research on the effects of graphene oxide (GO) as a nanocomposite element on polymer morphology and resulting property modifications including mechanical, barrier, and electrical conductivity. The effects on mechanical enhancement related to stress measurements in particular are a focus of this review. To first order, varying levels of aggregation of GO in different polymer matrices as a result of their weak inter-particle attractive interactions mainly affect the nanocomposite mechanical properties. The near surface dispersion of GO in polymer/GO nanocomposites can be investigated by studying the surface morphology of these nanocomposites using scanning probe microscopy such as atomic force microscope (AFM) and scanning electron microscope (SEM). In the bulk, GO dispersion can be studied by wide-angle X-ray scattering (WAXD) by analyzing the diffraction peaks corresponding to the undispersed GO fraction in the polymer matrix. In terms of an application, we review how the hydrophilicity of graphene oxide and its hydrogen bonding potential can enhance water flux of these nanocomposite materials in membrane applications. Likewise, the electrical conductivity of polymer films and bulk polymers can be advantageously enhanced via the percolative dispersion of GO nanoparticles, but this typically requires some additional chemical treatment of the GO nanoparticles to transform it to reduced GO. ª 2015 Production and hosting by Elsevier B.V. on behalf of King Saud University.
