In this research, the polymer- clay nanocomposites which different amino acids and poly peptides located instead of sodium ion were studied by molecular dynamic methods. Energy and volume of the formed clays were analyzed to show the effect of central amino acids or poly peptides on clay properties. Remarkable result which obtained is that by increasing the number of amino acids the volume and distance of layers is decreases. Additionally the increasing the polypeptide chain makes it more voluminous and responsible to use in modification of polymer properties.
