Abstract: This study is purposed with the preparation of polyacrylamide/Polypyrrole hydrogel composite, in which the hydrogel of crosslinked polyacrylamide is a matrix and Polypyrrole is an electro-conducting component. The effects of synthesis conditions on the structure of the composite systems, their ability to swell in water, and mechanical characteristics are studied. The proposed synthesis procedure allows production of a bulk electro-conducting phase of Polypyrrole in the hydrogel matrix. The effect of crosslink density of hydrogel on the character of Polypyrrole distribution in the matrix is studied. The above composites combine the electrical characteristics of Polypyrrole with high elasticity and the ability to repeatedly swell the cross-linked poly (acrylamide).
