Effect of Nanoparticles on Co-Continuous Morphologies

Even though fillers are usually introduced into polymer blends of droplet-matrix morphology, a few reports dealing with filled co-continuous blends can be found in the 

Effect of annealing on the morphology of (PP/maleated PP)/ethylene-octene copolymer 60/40 blends (a) unfilled blend and (b) blend containing 5 phr silica. The label on the micrographs represents the annealing time. The ethylene-octene copolymer has been extracted. 

TEM images of (PP/maleated PP 90/10)/ethylene-octene copolymer 50/50 composites, (a) 0 wt% Si02 (b) 1 wt% Si02 and (c) 5 wt% Si02. Scale bar 500 nm. Dark domains represent the stained ethylene-octene copolymer phase. (Reprinted from Lee, S.H. et al.. Polymer, 51,1147,2010.)
