Semi-interpenetration with conducting polyanilines on poly(acrylamide-co-kaolin) composite

Abstract

In this work, clay minerals such as kaolin particles were embedded within the network of poly(acrylamide) hydrogel (PAAm) using free radical solution polymerization method. Aniline monomer was absorbed in the network of PAAm/Kaolin composite hydrogel and followed using free radical solution polymerization at room temperature. The novel semi-interpenetrating network was comprised of linear polyaniline immersed in PAAm/Kaolin composite. Electrical conductivity of the hydrogels was measured using four-probe technique. The conductivity for the prepared new semi-interpenetrating polymer network (s-IPN) is found to be 1.1 ×10−4 S.cm−1. Thus, a new s-IPN composite hydrogel with good conductive properties was prepared.
