The obtained higher current in FLGS is due to sp2 conjugation in FLGS without any functional group. Figure 2:(a)XRD pattern, (b) UV-Vis, (c) I-V characteristics of FLGS. The reversible wettability transition fromhydrophobic to high hydrophilic nature of FLGSwas accomplished by Ultraviolet (UV) irradiation and stored in vacuum [19]. The irradiation duration– dependent contact angle (CA) of water on FLGS shown in figure 3 in ambient temperature was measured by an optical Contact angle meter. According to this figure CA slowly decreases from 87.160 to 52.930 for FLGS showing to UV irradiation from 0 to 120 minutesin step of 30 minutes. Therefore the hydrophobic state can be transferred to the highly hydrophilic state under UV irradiation within 2 hour. Then the samples were heated at 800 C for 5 hours in vacuum and measured the contact angle. Figure 4 shows the transition from hydrophilic to hydrophobic of the obtained graphene sheet. From the figure, it can be observed that the contact angle increases towards hydrophobic using vacuum storage after 5 days of the hydrophilic graphene sheet which was obtained by the UV irradiation. From the above experiment it is clearly seen that the transition from hydrophobic to hydrophilic state under UV 3PDF Image | graphene sheets (FLGS) prepared by an electrochemical method
