This study is concerned with the behavior of samples based on nylon 6/zinc (Ny6/Zn) composite material in high salinity water that contains NaCl (3.5 wt%) and in aqueous solution of HCl (0.5 N and 1 N). The samples were obtained from parts prepared by in situ anionic ring-opening polymerization of є-caprolactam (CL) in the presence of zinc (Zn), as filler (15 wt%) using the rotational molding technique. This type of composite was evaluated by the testing of swelling degree, structural modifications, evolution of hydrogen and electrochemical behavior. The properties of Ny6/Zn composite material have ascertained through the combined use of more analysis methods: attenuated total reflectance Fourier transform infrared spectroscopy, wide-angle X-ray diffraction technique, scanning electron microscopy, swelling and electrochemical measurements. It was revealed that regarding swelling behavior the Ny6 matrix has an important role while Zn filler contributes especially to the (electro)chemical corrosion.
