Abstract: The MoS<subscript>2</subscript> nanotubes (NTs) were added to polyvinylidene fluoride (PVDF) with the aim to adjust its friction properties. Thin films and thin nanocomposite coatings were prepared with different MoS<subscript>2</subscript> NT concentrations. Morphology and distribution of the NTs inside the nanocomposites were studied by optical and electron microscopy. Raman spectroscopy performed before and after friction tests was used to evidence partial transformation of PVDF into piezoelectric phase due to friction caused drawing. Friction tests in flat-on-flat and ball-on-disk configuration with AISI 316 stainless steel as counterpart revealed a strong reduction of coefficient of friction. [ABSTRACT FROM AUTHOR]
