Abstract
In this paper, tungsten, bismuth, tin, and copper powders were used as additives in the fabric coating to obtain lead-free and flexible x-ray shielding material. The X-ray attenuation and the flexural properties of the coated fabrics were investigated considering the medical protection requirements. The results showed that tungsten additives in silicone rubber coating had better attenuation ratios than the samples that contain tungsten–tin, bismuth, and tungsten–copper, at same additive volume ratios. Moreover, the increment of tungsten volume ratios in coating blend resulted in higher shielding performance at same effective thicknesses and the lower silicone rubber amount in coating lead to compose thinner and lighter fabrics for equal protection level. In addition to that, the samples with tungsten–tin, bismuth, and tungsten–copper showed remarkable attenuation properties, and the results were found to be coherent with the theoretical values. The flex resistance and the flexural rigidity of the samples with tungsten content were also investigated. The coated fabrics with different powder loadings and thicknesses showed good resistance against repetitive folding; on the other hand, the results showed that the increment of tungsten amount in the coating resulted in stiffer fabrics.
