In order to explore the application feasibility of tungsten in electromagnetic shielding and radiation protection,tungsten metal was deposited on the surface of high density polyester filament fabric by RF magnetron sputtering,and the physical and chemical structure of tungsten film was explored.The electromagnetic shielding performance of tungsten metal fabric were tested.The results shown that with the increase of sputtering power,the crystallinity and orientation of tungsten increased,and improved the continuity and uniformity of tungsten film.With the increase of sputtering pressure within a certain range,the crystallinity and uniformity of tungsten film increased.But with the increase of sputtering pressure to a certain extent,the uniformity of tungsten film decreased.With the increase of sputtering time,the continuity and uniformity was improved.After experimental optimization,the average value of electromagnetic shielding performance of tungsten/polyester composite fabric with conductive cloth under 60W,1.0Pa and 60min sputtering conditions was up to 94 dB,which shown good electromagnetic shielding performance.
