Validation of rheological responses for morphological evaluation of incompatible polyamide 12/thermoplastic elastomer blends filled with nanoclay

Polyethylene terephthalate/low density polyethylene/titanium dioxide blend nanocomposites: Morphology, crystallinity, rheology, and transport properties

“…The morphological aspects analyzed above have not been investigated, so far, for PET/LDPE/TiO 2 systems, as far as the authors are aware. In the literature, the effect of adding TiO 2 on the morphology of a PET/PP blend (rich in PP) has been studied . As reported by Li et al ., in the case of the PET/PP binary blends the particles locate in the PET droplets .…”

“…In literature, viscoplastic behavior has been observed during frequency sweeps in the linear viscoelatic regime for LDPE/clay nanocomposites and PA/SEBS/clay blend composites . However, as far as we know, a study on the effect of the presence of fillers in the viscoplastic behavior under extrusion flow has not been carried out.…”

“…In the literature, the effect of adding TiO 2 on the morphology of a PET/PP blend (rich in PP) has been studied. [19][20][21][22][23] As reported by Li et al, in the case of the PET/PP binary blends the particles locate in the PET droplets. [21][22][23][24][25] For TiO 2 nanoparticles treated with polyalcohol, Li et al observed that the nanoparticles were located at the interface and in the PET phase.…”

“… Also in the nonlinear regime, but to a lesser extent, focusing on the relationship between droplet size and a nonlinearity parameter derived from Fourier analysis of the sinusoidal stress and strain . However, the properties under continuous flow have been scarcely analyzed for polymer blends containing fillers, currently called blend composites …”

“…[16][17][18][19] However, the properties under continuous flow have been scarcely analyzed for polymer blends containing fillers, currently called blend composites. 20 Regarding PET/polyolefin blends, some works have been reported for PET/PP blends containing TiO 2 . [21][22][23][24][25] These studies focus on the morphology and the effect of TiO 2 to obtain microfibrillar composites, being all the blends rich in PP phase.…”
