摘要

Recently, there has been a growing interest in the use of flexible electronics for optoelectronic memristor devices and energy storage applications. In this study, we propose a flexible and transparent hybrid composite made of a poly (vinyl alcohol)–reduced graphene oxide (PVA/rGO). The GO and rGO fillers were prepared using a modified Hummer’s technique and hydrazine monohydrate as a reactive chemical agent. Our focus is on investigating the impact of varying weight percentages (0%, 1%, 3% and 5%) of of rGO in PVA with improvement in the structural and optical properties. The PVA/rGO gel was deposited on flexible PET/ITO substrates using a spin-coating process and analyzed using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR) and photoluminescence (PL) spectroscopy. The degree of crystallinity was found to decrease from 57.6% to 42.57%. The FTIR spectra showed significant band shifting and reduced transmittance intensity in the doped materials, indicating the formation of hydrogen bonds between the matrix and the dopant. UV- visible spectra measurements were used to analyze the optical performance, and it was found that the direct energy gap (Eg) of the PVA film decreased from 3.33 eV to 2.87 eV due to the doping of rGO. The prepared flexible assembly exhibited improved structural and optical properties, making them promising materials for optical storage and advanced flexible optoelectronic memristor applications.
