Graphene dispersion stabilized by PEG-grafted polystyrene-co-maleic anhydride copolymers |
| 초록 |
PEG-grafted polystyrene-co-maleic anhydride copolymer was used for the aqueous graphene dispersions prepared by using ultrasonic process. Various amount/ratios of copolymers were mixed together with reduced graphene oxide in deionized water. The graphene dispersions were then investigated using UV-Visible spectroscopy (UV-Vis), transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-Ray photoelectron spectroscopy (XPS) and on-line turbidity (turbiscan). All the samples showed good dispersibility and the samples having concentration over 0.1 mg/mL-water remained well dispersed for at least a month. |
