Strain hardening behavior of polymer blends with fibril morphology

Facile Preparation of Open‐Cell PP/TPS Blend Foams Using Water as a Blowing Agent

“…Therefore, it was supposed that the starch fibers might be formed due to the shear or elongation flows during the extrusion process. Similar phenomenon has also been found in other blend systems . It is noteworthy that within the cell walls between adjacent cells, more starch droplets coalesced and transferred into fibers and the fiber orientation was also changed, as seen in Figure b.…”

Tuning viscoelastic and crystallization properties of polypropylene containing in-situ generated high aspect ratio polyethylene terephthalate fibrils

“…Recently, the strain hardening behavior of polymer blends with fibril morphology has been reported [8e10]. Dramatic improvements in strain hardening response of polyethylene (PE) was observed through the in situ fibrillation of 1 wt% PP [8,9]. Similarly, the fibrillation of 1 wt% polybutylene terephthalate (PBT) in polylactic acid (PLA) also resulted in marked improvements in strain hardening [10].…”

Numerical study on the effect of viscoelasticity on drop deformation in simple shear and 5:1:5 planar contraction/expansion microchannel

“…Thus, it is essential to understand drop dynamics in two-phase systems to generate a targeted shape. In the conventional industries, drop deformation problem is also quite important in polymer blends [9][10][11][12] and polymer processing [13] to control the microstructure and rheology and thus to enhance the product quality.…”
