Variety of emaradine salt films of PANi were formed on the surface of glass substrate by in-situ chemical polymerization in HCl acidic aqueous solution. The indentation technique shows that the mechanical characterization of the PANi films was modified depending on the polymerization time. The film formed during the initial stage (nucleation) exhibited higher hardness, reduced and storage modulus than that of the film formed during the next following stage (growth). The stronger coupling of the ANi radicals with the glass substrate surfaces during the nucleation stage was accounted for the feature. © Anita Publications. All rights reserved.
