Rheology of Sub-micron Thick Polymer Melt

摘要

Polymeric nanocomposites (PNCs) have attracted a lot of attention due to its potentials in superior mechanical properties,conductivity,gas permeability,to name a few,that very much surpass what conventional polymer composites can provide.The success of PNCs requires a good dispersion of the reinforcement phase in the polymer matrix.In these well-dispersed PNCs,submicron,or even nanometers thick polymer is confined between reinforcement phases.Understanding the dynamics of such thin polymer melts confined between two rubbing surfaces can hence provide important insight on both the dispersion mechanisms and processing of PNCs.
