Peroxodisulfate-induced polymerization of aniline in aqueous acidic (HCl) media using the support of a water soluble polymer polyacrylamide, PAAm produced polyaniline (PANI) in aqueous dispersion/solution having high stability and easy processability. PAAm support apparently allows limited grafting of PANI on it in addition to causing a template effect through hydrogen bonding between segments of the two polymers; this explains fairly uniform and high degree of dispersion or solubility of PANI with exceptional storage stability. Aqueous and isolated dry PANI-PAAm composites were characterized spectroscopically (UV-Vis and FTIR), thermally (TGA, DSC) and with respect to their electrical conductivity at different PANI loadings and temperatures. The morphology of the composites were studied by transmission electron microscopy (TEM) and scanning electron microscopy (SEM). © 1999 Elsevier Science Ltd. All rights reserved.

Studies on stable aqueous polyaniline prepared with the use of polyacrylamide as the water soluble support polymer

European Polymer Journal

The present work reports an easy route for synthesis of polyaniline (PAn) in stable aqueous solution/dispersion form, using poly(vinyl alcohol) (PVA) as an efficient steric stabilizer. Resulting composite successfully combines desirable physical properties like mechanical strength, solution processibility and electrical conductivity of PVA and PAn components. The composite was subjected to versatile characterizations and its different physical properties (especially optical, thermal, mechanical and electrical) were explored. Free standing films can be obtained from the solutions, which exhibit important microwave shielding property over the X-band. This has enhanced the importance of this material to a large extent. © 2001 Elsevier Science B.V. All rights reserved.
