- Abstract
A simple, two‐step aqueous polymerization was introduced to synthesize a polyacrylate (PAC)/polypyrrole (PPy) hydrogel. The hydrogel had a semi‐interpenetrating network (semi‐IPN) structure with a loose, three‐dimensional PAC network and a one‐dimensional PPy conjugated chain. The presence of PPy led to a higher conductivity (9.1 mS/cm) for the PAC/PPy hydrogel. Because of the acrylate group on PAC and the imine group on PPy, the hydrogel showed typical pH sensitivity with two water absorption peaks at pH 4–6 and pH > 11. The loose semi‐IPN structure endowed the hydrogel with good load and release functions. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
