Rheological and structural details of biocidal iPP-TiO2 nanocomposites

► A cost-effective process allows preparation of biocidal iPP-TiO2 nanocomposites. ► Time-temperature superposition principle is validated in these iPP/TiO2 nanocomposites. ► Presence of TiO2 slightly increases iPP crystallinity and its most problable crystallite size. ► TiO2 nanoparticles induce a nucleant effect within the iPP matrix.
