摘要：

In the present course of investigation synthesis and properties of a series of polyaniline-PVA-based semi-IPNs are described. PVA component in a PAn-PVA composite solution/dispersion, prepared by steric stabilization mechanism, was crosslinked to give rise to the present IPN. Formaldehyde was used as the crosslinker and the IPNs were isolated in the form of flexible and free-standing films. Morphological and structural properties of the system were studied from FTIR spectra and SEM images. Different solid state properties, viz. dc conductivity at different temperatures, thermal and mechanical properties and moisture regain were also studied and a series of films with good mechanical and thermal properties were obtained.
