“…Figure 1(c) depicts the Raman spectrum of 3D graphene in which two prominent raman bands were clearly visible that corresponds to D and G band at 1357 and 1596 cm −1 , respectively 54 – 56 . The appearance of D band arises due to the activation of the first order scattering process of sp 3 hybrid carbons, which is attributed to dislocation defects in graphene sheets 57 . Similarly, the SEM studies of as-synthesized 3D graphene were carried out, see (Fig.…”

Portable and matured energy storage devices are in high demand for future flexible electronics. Flowery shaped MoS2 nanostructures with porous and flake like morphology was used to study the supercapacitive nature with specific capacitance (Csp) of 169.37F/g, the energy density of 28.43 Wh/Kg and power density of 10.18 W/Kg. This nanoflower like architecture was decorated on 3D-graphene on Graphite electrode to design the solid-state-supercapacitor prototype device of dimensions of 23.6 × 22.4 × 0.6 mm3 having considerable high Csp of 58.0F/g and energy density of 24.59 Wh/Kg, and power density of 8.8 W/Kg. Four fabricated supercapacitors were connected in series for real state practical demonstration using the light emitting diode that remains enlightened for 40 s by charging it only for 25 s. This study demonstrates the 3D-graphene/MoS2 nanohybrid has a quite high overall potential window nearly about 2.7 V (−1.5 to +1.2 V) in KOH-PVA medium which can be used for the development of solid-state supercapacitors thereby completely eliminating the need for any expensive ionic liquid mediums thus building an exciting potential for high-performance energy storage/transfer devices.

“…[40][41][42] The D band arises from the activation in the first order scattering process of sp 3 carbons, which has been attributed to dislocation defects in graphene sheets. 43 And the intensity ratio of D and G bands expresses the sp 3 /sp 2 carbon ratio, a measure of the extent of defects. 40 This suggests that the D/G ratio can be used to monitor the extent of defects by ultrasound.…”

Poly(vinyl alcohol) (PVA) functionalized graphene (f-G) was prepared by ultrasonication of pristine graphene (p-G) in a PVA aqueous solution. PVA macroradicals formed by sonochemical degradation of the PVA solution were successfully trapped by graphene and grafted onto its surface. This was confirmed by transmission electron microscopy, atomic-force microscopy and 1 H NMR measurements. The content of PVA on graphene was estimated to be y35%. The f-G could be well dispersed in the PVA matrix by a simple solution mixing and casting procedure. Due to the effective load transfer between f-G and PVA matrix, the mechanical properties of the f-G/PVA films were significantly improved. Compared with the p-G/PVA films, a 12.6% increase in tensile strength and a 15.6% improvement of Young's modulus were achieved by addition of only 0.3 wt% f-G. Moreover, our simple ultrasonication technique could enable us to functionalize graphene with other polymers.

“…It is known that [34], in synthesis of the fullerene, the ions bombarding the cathode do not sputter it, but, conversely, are incorporated into its structure to give a cathode deposit. In this case, both the amount of the deposit formed and its structural features depend on the composition and energy of ions bombarding the cathode.…”
