| Abstract | ||||
| Styrene butadiene Rubber (SBR) containing Surface Modified Nano particles Clay by Electron Beam Radiation dose 100 KGy (SMEB) and non-modified Nano particles Clay were prepared. Direct current measurements were established for knowing the conduction type of charge transport passing through the modified (SMEB) and unmodified SBR/clay composite samples. Where, it is deduced that Poole-Frenkel conduction mechanism was found to be predominate for all clay-SBR samples. The mechanical Tensile strength and elongation at break were estimated from stress strain curves measured and we realize the tensile strength of SBR matrix increases appreciably with clay loading up to 15 phr, the polymer-filler interaction for modified clay loaded samples is improved slightly higher than unmodified clay samples and From calculations of the slope of the Vro/Vrf versus C/ (1-C) plot. The slop value is founded to be positive which mean that reinforcing by filler having good polymer-filler interaction. Elongation at break increases slightly with clay loading up to 10 phr and then abrupt decrease is detected at 15 phr clay loading for all samples. | ||||
