The use of functionalized nanoparticles as non-specific compatibilizers for polymer blends
(65–71)Polymers for Advanced Technologies 22 #1 (2011)
Zhang et al have shown that the inorganic nanosized filler can also serve as a compatibilizer by forming in situ grafts with the immiscible polymers. We also use theoretical studies to show that the aspect ratio and the bending energy of the fillers play a key role in the compatibilization process. Our results indicate that the compatibilization is a general phenomenon, which should occur with all large aspect ratio nanofiller additives to polymer blends.  (RDC 2/4/2011)

New (PP/EPR)/nano-CaCO3 based formulations in the perspective of polymer recycling. Effect of nanoparticles properties and compatibilizers
(896–903)Polymers for Advanced Technologies 21 #12 (2010)
Mnif et al of France and Tunsia studied the phase structure of composite polypropylene (PP)/ethylene–propylene–rubber (EPR)/coated nano-CaCO3 composites, used in the manufacture of bumpers, with and without compatibilizers.  Blends of various compositions were prepared using a corotating twin-screw extruder. The experimental results indicated that the dispersion of nanoparticles in (PP/EPR) depends on their surface (stearic acid and fatty acid coatings).  According to the nature of the compatibilizers and surface treatment, it is believed that the synergistic effect of both the EPR elastomer and CaCO3 nanoparticles should account for the balanced performance of the ternary composites.  (RDC 2/4/2011)
