“…This confirmed that the GO and CNTs are well-mixed during the mixing process. Meanwhile, the graphitic skeleton peak at 1582 and 1651 cm −1 further confirmed the functionalization between GO and CNTs [30,31].…”

Graphene oxide (GO) was synthesized via a simple electrochemical exfoliation of graphite in a surfactant-containing aqueous solution. A novel custom-made surfactant, 1,4-bis (neopentyloxy)-3-(neopentyloxycarbonyl)-1,4-dioxobutane-2-sulfonate (TC14) was used to assist the exfoliation process. The structural and magnetic properties of prepared GO were examined using electron microscopies, micro-Raman, and Fourier transform infrared spectroscopies, and vibrating sample magnetometer (VSM). Room temperature VSM measurement showed a diamagnetic response of pristine GO under a high magnetic field. This indicated the low defect and the absence of any impurities in the synthesized GO. Simple mixing of GO and carbon nanotubes (CNTs) was also done to study their magnetic properties. CNTs were initially synthesized from waste engine oil using thermal chemical vapour deposition. It was found that the addition of magnetic CNTs has successfully induced the ferromagnetism in the GO sample. The saturation magnetization and average coercivity of GO/CNTs were observed to be 6.13 memu and 345.12 G, respectively. This study offers a low cost and simple method to induced magnetism in GO as compared to the common chemical modifications of GO.

“…Dispersion GO assisted triple-tails surfactant, TC14 plays a significant role to fabricate high performance GO/NRL polymer nanocomposite. As reported in previous work [47], a good dispersion in the polymer matrix can be achieved by including surfactant in the composite materials. This was due to the improvement in the hydrophobic interaction between the surfactant and GO sheets layer, thus lowering the van der Waals between the graphene sheets.…”

The use of surfactant in achieving high stabilization and exfoliation graphene oxide (GO) was seen to be the crucial factor in improving the quality and quantity of GO produced via electrochemical exfoliation method. Therefore, this chapter is presenting the physical characterizations that successfully showed the stabilization of GO by various anionic surfactant. The uniqueness in this work was lie on the number of tails surfactant which consists of single-, double-and triple-tails, and the comparison study in terms of electrical conductivity between the commercial and custom-made surfactants. Moreover, the effective stabilized-GO was further explored in super capacitor application. This work opens a new window for green and low-cost GO material as conductive electrodes material.

“…The addition of graphene structures determines strong chemical interactions in the matrices and their homogenous dispersion generates uniform stress distribution, leading to an important increase in mechanical strength of the composites [21,22]. Previous reports state that the improvement in the mechanical properties of polymers combined with graphene is determined by the interfacial interaction of the graphene with the polymer matrix and by the efficient transfer of the exterior load from the polymer to the filler [4,32]. Although the graphene loading was rather low, at 1 and 2%, it improved the compression parameters especially at 1% loading.…”

The Influence of Graphene in Improvement of Physico-Mechanical Properties in PMMA Denture Base Resins

The clinical performances of dental materials depend on their mechanical profiles, determining their long-term deformation and wear resistance. This paper describes a study on the mechanical properties, water absorption and morphological properties of a polymethyl methacrylate (PMMA) resin enriched with graphene-silver nanoparticles (Gr-Ag). Two different concentrations—1 and 2 wt.%—of Gr-Ag were loaded into the PMMA material. For the mechanical characterization, the compression behavior, flexural strength and tensile strength were evaluated. Optical microscopy in polarized light and scanning electron microscopy were used for filler analysis. The filler addition led to an improvement in all mechanical properties, with slight changes being derived from the filler content variation. Gr-Ag use led to an increase in the applied maximum loads. Moreover, 1 wt.% Gr-Ag determined an increase of 174% in the modulus of rupture, which indicates high flexibility.
