Polymer–Nonleaded Metal Tungsten Composites

Nonleaded metal–polymer tungsten and sendust composite can be applied for X-ray shielding as a reliable substitute material for lead. The lamination order of tungsten film and sendust composite film affects the final performance of the laminated composites.Polymer–nonleaded metal tungsten composites had been studied the effects of multilayer structure on X-ray shielding ability. Though the metals were nonleaded, the metal contents were low, and the composite films were thin, the composite films showed favorable X-ray shielding ability due to the uniform dispersion of metal particles in the polymer matrix and the flake alignment of tungsten. This means that multi-layered particles can effectively absorb the penetrating photons and they fill the pin holes in the composite. More uniformly aligned tungsten shows better shielding effect than randomly oriented lead.
