Electromagnetic radiation shielding of NBR rubber composites loaded with magnetite and manganese dioxide

Abstract This study presents the preparation of acrylonitrile butadiene rubber (NBR) composites loaded with different concentrations of electromagnetic radiation shielding materials like magnetite and manganese dioxide. The composites were subjected to electron beam irradiation at 50 kGy and characterized using Fourier-transform infrared spectroscopy (FTIR) and X-ray diffraction (XRD) tools. The hybrid fillers showed a strong interaction with the NBR rubber matrix, improving mechanical properties like tear strength. Electrically conducting of these filler materials that loaded NBR rubber matrix find a lot of attentions for electromagnetic shielding materials. All prepared samples were measured using vector network analyzer (VNA) with aid of an X-band wave guide to evaluate its performance as an electromagnetic interference (EMI) shielding material. The results showed that all samples improved shielding properties and can be used as low-cost, lightweight, and good-performance shielding materials.
