| Abstract: | Poly(ionic liquid)s have been demonstrated as high efficient CO2 absorbents. In the current study, a kind of poly(ionic liquid)s, Poly2‐(methacryloyloxy)‐ethyl] trimethylammonium tetrafluoroborate (PMATMA]BF4]) was used to functionalize graphene oxide (GO). The hybrid in which PMATMA]BF4] was covalently bonded on GO platelets was prepared by a simple method, that is, traditional radical polymerization. The characterizations based on transmission electron microscopy, scanning electron microscope, Fourier transform infrared spectroscopy, Raman spectroscopy, X‐ray diffraction, and X‐ray photoelectron spectroscopy demonstrated the graft of PMATMA]BF4] on GO. N2 adsorption measurements indicated that PMATMA]BF4] also greatly increased the specific surface area of GO. Due to the higher specific surface area and the CO2 affinity of PMATMA]BF4], the GO‐PMATMA]BF4] hybrid exhibited a much higher CO2 adsorption capacity compared with GO, GO‐NH2, and PMATMA]BF4]. Their study showed that the combinations of poly(ionic liquid)s and GO could be promising CO2 absorbents. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2017 , 134, 44592. |
