The paper presents a facile and effective method to exfoliate bulk niobium diselenide (NbSe2) into nanosheets which were used as nanofillers to improve the tribological properties of epoxy coatings. X-ray diffraction (XRD) analysis indicates that the hexagonal crystal structure of NbSe2 nanosheet is preserved after ball milling. Transmission electron microscopy (TEM) and atomic force microscope (AFM) observations show that NbSe2 nanosheets were produced with sizes in hundreds of square nanometers and graphene-like structure. The tribological properties of NbSe2/epoxy composite coatings were systematically investigated and results show that they possess better friction-reducing and anti-wear performances due to the addition of NbSe2 nanosheets. It is demonstrated that the superior tribological properties is ascribed to a transfer film formed by NbSe2 nano sheets preventing a direct contact between steel ball and coating during the friction process. Furthermore, this work shows the potential applications of two-dimensional NbSe2 nanosheets as reinforcing nanofillers in polymer matrix. (C) 2016 Elsevier B.V. All rights reserved.
