Use of Rheology to Assess Structures in Polymer Nanocomposites
… with improved dispersion-states and properties. Nanofillers such as undoped and nitrogen-doped multi-walled carbon nanotubes (MWCNTs) and organically modified clays as well as more recently developed nanofillers such as graphene nanoribbons (GNRs) were employed for this purpose. In this context, …
