Abstract
New types of stimuli responsive composite polymer systems containing electro- and pH-responsive components are prepared. In these systems, the spatial structure of the active component phase is determined by the matrix of porous polyethylene films that play the role of nanosized containers for hydrogels and electroconducting polymers. Effects of the conditions of the synthesis of active components on the electro-physical properties of the composite system, its pH-responsivity, and reversibility of swelling-contraction processes in media with various pH values are investigated. It is shown that the matrix structure affects the magnitude of the response to the external stimuli and the morphological features, swelling ability, electric conductivity, and mechanical behavior of the systems.
