“…According to X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, X-ray diffractometer (XRD), and Fourier transform infrared spectroscopy (FTIR) chemical characterization analysis, it is proposed that the excellent conductivity and rich surface functional groups of these two-dimensional materials can effectively provide heterointerfaces to form a quasi-three-dimensional heterostructure and improve the interaction between the fillers and polymer matrix, promoting the electroactive β-phase, and consequently enhancing the output power density of PENG. …”
