▎ 摘　　要

In this study, a facile melt-mixing technique was employed as a simple and inexpensive technique to prepare a quasi-2D graphene-PVDF (QGF-PVDF) nanocomposite based FET (QGF-FET) device. The morphological and optical properties were studied using field emission scanning microscopy (FE-SEM) and UV-visible diffusereflectance spectrum (UV-Vis DRS). Morphological study reveals that the thin films of QGF-PVDF are highly affected by the calcination temperature, as reflected also in their optical properties. The optical band gap reveals a Bathochromic shift due to increased calcination time from 12 to 24 hr. Our results further suggest that the QGFFET device can potentially exhibit superior photodetector performance for photocurrent up to 20 mA.
