Abstract

Several porous material systems (e.g.. hydrogels, conducting polymers, electrorheologic fluids) make possible a control of their properties in response to an appropriate stimulus (and viceversa) and therefore. they belong to the class of intelligent materials. In the present paper we propose a first classification of intelligent porous systems dividing them in three main classes: porous material as semi-permeable media, as reservoir and delivery systems and as biphasic composites with large interfacial area between solid and fluid phases. Then we present a continuos model to describe the passive mechanical behaviour of a generic porous conducting polymer saturated by a fluid. The model is solved for a stress-relaxation test and it is verified in the specific case of a doped polypyrrole porous matrix saturated by an electrolytic solution. The goodness of fit between experimental date and theoretical data confirms the validity of the model.
