Sulfur-doped graphene laminates for EMI shielding applications
Journal of Materials Chemistry C, 2015Co-Authors: Faisal Shahzad, Pradip Kumar, Yoon Hyun Kim, Seunghwan Lee, Seunggun Yu, Soon Man Hong, Chong Min KooAbstract:Herein, for the first time, we demonstrate that a laminated structure of sulfur-doped reduced graphene oxide (SrGO) provides significant potential for electromagnetic interference shielding applications. Herein, for the first time, we demonstrate that a laminated structure of sulfur-doped reduced graphene oxide (SrGO) provides significant potential for electromagnetic interference shielding applications. In this study, SrGO was prepared through the reaction between graphene oxide and Hydrogen Disulfide (H 2 S) gas at elevated temperatures. The doping degree of S was controlled through varying the time and temperature of the reaction and the maximum doping content of 5.6 wt% was achieved. Because of the n-type doping contribution of the S atom to the doped graphene, SrGO laminate not only revealed a 47% larger electrical conductivity (75 S cm −1 ) than undoped reduced graphene oxide laminate (51 S cm −1 ) but also revealed 119% larger EMI shielding effectiveness (33.2 dB) than the undoped one (15.5 dB) at the same sample thickness.
