Preparation of MoS2 Nanosheets and PVDF Nanofiber

Abstract

Recently, 2D transition metal dichalcogenides (TMDCs) (e.g., MoS2, WS2, MoSe2, WSe2, MoTe2, etc.) have been attracting a wide range for research interest due to their favorable mechanical, chemical, electrical and optical properties. Among them, MoS2 have been widely used as a functional material in diverse fields such as lubrication, electronic transistors, batteries, photovoltaics, and catalysis. Recently it has been also observed that MoS2 nanostructure is possessing piezoelectric functionality. On the other side PVDF nanofiber based nanogenerator is a good flexible device for scavenging mechanical energy from environment. Nanofiber can be generated by using electrospinning process. In this article a brief idea about PVDF nanofiber preparation is the key focus of this paper. Material and structural analyses on fabricated nanofibers using tools such as XRD (X-ray diffraction), FTIR (Fourier transform infrared), FE – SEM (Field emission scanning electron microscopy) toward the fundamental characterizations of piezoelectric nanofibers are also described. MoS2 can be incorporate in PVDF for getting better performance of nanogenerator. Here MoS2 nanosheets preparation and characterization has been done.  Summarize the report by the application of nanofiber based nanogenerator as energy scavenging applications.
