Polymer blend is known as the simplest method to obtain a new material by just blending two or more materials with suitable mixing technique. Most of the material engineers play their effort to improve the compatibility and miscibility of the blend components since this gives significant effect on the properties of the resulting materials. However, some of the creative engineers used the shortage of the immiscible blend material in the electronic application by inducing the double percolation with the aim to improve the electrical conductivity of the inherently insulating polymeric materials and at the same time conserve the attractive properties of the polymeric matrix. Herein, unfilled NRL/LSR and filled NRL/LSR with 7phr of GNP-SDS blend materials were prepared in order to investigate the effect of LSR content on the crosslink density, tensile properties, tear strength and electrical properties of the blend materials. It was found that the physical and mechanical properties of the materials declined with the increasing LSR content. Nevertheless, the modulus and the electrical properties of the filled NRL/LSR have been improved.
