The G-Act hybrids were characterized by Fourier transform infrared spectroscopy, ultraviolet-visible spectrophotometry, thermal gravimetric analysis and Raman spectroscopy. X-ray photoelectron spectroscopy confirms that the binding energies of APA and its derivatives shifted to higher values, revealing pronounced charge transfer at the interface of graphene and organic molecules.展开更多
