The inquisite nature of human minds to novel composite materials with contradicting behaviours has resulted in the blending of extremely different materials like rubber with metals resulting in Rubber Metal Composites have been prepared by incorporating commercial metal posders to the rubber matrix. Many of these metal powders used to prepare the composite were of micron size dimensions and were added at 5 to 20 phr to the rubber matrix, to impart the desired properties. The past decade has seen significant progress in our understanding of the preparations of nano metals of defined dimensions and specific shapes like nano spheres, nano rods and nano wires etc. This naturally has stimulated research interest in the preparation of vaious rubber metal nanocomposites. The renewed interest in the above field is due to the fact that metal particles in nano meter scale dimensions can impart novel properties to the composites. as in the case of any other rubber nanocomposites, the dispersion of nano metals in a homogenous manner within the rubber matrix is a haunting and challenging problem.
