Natural Rubber Composites

Commonly used shielding materials while X-ray imaging by clinical persons is based on lead but incessant contact with this toxic material can pave way to severe health problems. Polymer composites, embedded with lead-free additives, especially based on natural rubber can be chosen as a suitable alternative candidate due to its lightweight, cost-effectiveness and capability to absorb regular energy region of X-ray used in medical imaging. Rubber composites were prepared with modified rare earth oxides at different filler loadings. The characterization of the filler reveals that their size falls in the nanoregime, which, in turn, supplemented to the superior properties of the composites. Mechanical properties were found to increase with filler content. X-ray shielding studies were done at different tube voltages and thicknesses and the results prove the efficacy of materials to be considered as a promising shielding resource.

Ground tire rubber from car and truck was modified using microwave irradiation at variable time. The irradiated ground tire rubber was used as filler in composites based on natural rubber. The composites, with high content of ground tire rubber, were prepared using an internal batch mixer and subsequently cross-linked at 160℃. The influence of the ground tire rubber source (car/truck) and irradiation time on structure, physico-mechanical behaviour, thermal properties and morphology of natural rubber/ground tire rubber composites was studied. The interfacial interactions between ground tire rubber and natural rubber as function of ground tire rubber source and irradiation time were evaluated by Fourier transform infrared spectroscopy, thermogravimetric analysis, tensile tests, swelling measurements and scanning electron microscopy. The results showed that irradiation of ground tire rubber slightly enhanced tensile properties and cross-link density of natural rubber/ground tire rubber composites. This effect was more evident in the case of ground tire rubbertruck because of its higher content of natural rubber and was reflected in changes in the interfacial adhesion, which were confirmed by the results of Fourier transform infrared spectroscopy, thermogravimetric analysis and scanning electron microscopy analysis.

Protective materials based on lead are the usual X- ray shielding materials but their extended use leads to severe health problems due to the toxic nature of lead. Moreover, lead based materials are not appropriate for absorbing the regular energy region of X-ray used in medical field and hence natural rubber composites containing modified Gadolinium oxide (Gd2O3) as filler is suggested as an alternative. Natural rubber composites were prepared with organically modified Gd2O3 at various filler loadings.The structural features of modified Gd2O3 were examined using FTIR, X-ray diffraction and SEM. The particle size of organically modified Gd2O3 was found to be in the nano range which contributes to the enhanced properties of the composites. The increase of filler loading improved the shielding effectiveness of the rubber composites. Examination of mechanical and X-ray shielding properties show the effectiveness of the material to be used as potential shielding materials.
