TI  - Tuning the Morphology of HDPE/PP/PET Ternary Blends by Nanoparticles: A Simple 
      Way to Improve the Performance of Mixed Recycled Plastics.

AB  - Due to a very low mixing entropy, most of the polymer pairs are immiscible. As a 
      result, mixing polymers of different natures in a typical mechanical recycling 
      process leads to materials with multiple interfaces and scarce interfacial 
      adhesion and, consequently, with unacceptably low mechanical properties. Adding 
      nanoparticles to multiphase polymeric matrices represents a viable route to 
      mitigate this drawback of recycled plastics. Here, we use low amounts of 
      organo-modified clay (Cloisite(R) 15A) to improve the performance of a ternary 
      blend made of high-density polyethylene (HDPE), polypropylene (PP), and 
      polyethylene terephtalate (PET). Rather than looking for the inherent reinforcing 
      action of the nanofiller, this goal is pursued by using nanoparticles as a clever 
      means to manipulate the micro-scale arrangement of the polymer phases. Starting 
      from theoretical calculations, we obtained a radical change in the blend 
      microstructure upon the addition of only 2-wt.% of nanoclay, with the obtaining 
      of a finer morphology with an intimate interpenetration of the polymeric phases. 
      Rather than on flexural and impact properties, this microstructure, deliberately 
      promoted by nanoparticles, led to a substantial increase (>50  degrees C) of a softening 
      temperature conventionally defined from dynamic-mechanical measurements.
