Abstract

The discovery of graphene has aroused enormous scientific interests in fabrication and application of new two-dimensional (2D) materials in the past decade. As a typical layered graphene-like material, molybdenum disulfide (MoS2) shows the unique properties exhibiting great potential applications in the field of electronic and optoelectronic devices. Despite the enormous scientific interests aroused by MoS2, little attention has been focused on the progress in fabrication, properties, and applications of MoS2/polymer nanocomposites up to now. In this work, exfoliated molybdenum disulfide (MoS2) modified by a metal oxide (MoS2/MxOy) and carbon nanotubes (MoS2/CNT) was prepared and characterized by atomic force microscopy (AFM), Raman spectroscopy and transmission electron microscopy (TEM). The samples were used in polymer composite preparation by using an extruder blending method. Nanocomposites of polymer with nanofillers were obtained. The morphology, thermal properties, fire resistant properties and thermal conductivity of the nanocomposites were studied. We observed good flame retardance for all composites. All composites with exfoliated MoS2 exhibit greater potential for preparation of smart and functional nanomaterials with good thermal and fire resistant properties.
