原始语种摘要: In the last decades, one of the most critical issues concerning the control on the processing, structure and properties ofnanocomposites is related to the dispersion of nanofiller in the polymer matrix and internal interactions resulting in percolation.In this study, we investigate the rheological behavior in oscillatory and steady shear flow of poly(lactic) acid basednanocomposites incorporating 0 - 12 wt% graphene nanoplates (GNP) and multi-walled carbon natotubes (OH-MWCNT). Theeffect of the filler contents and aspect ratio on the viscosity and viscoelastic response is evaluated. Three rheological techniquesare used for estimation of rheological percolation threshold. Due to different aspect ratio and state of dispersion ofGNP and MWCNTs the percolation threshold differs significantly...
