The demand for the soft and flexible stretchable electronic has been increased due to the flourish development of electronic field nowadays. This can be achieved by incorporating graphene nanoplatelet (GNP) into natural rubber latex (NRL). This paper was aimed to investigate the effect of the GNP content on the properties of the NRL/GNP composites. The incorporating of GNPs into NRL increased the density and modulus of the composite but reduced the tensile strength, elongation at break and crosslink density. On the other hand, the NRL/GNP has reached the percolation threshold at 7phr of GNP, at this content the composite became electrically conductive.
