Self-reinforcing and toughening isotactic polypropylene via melt sequential injection molding
Polymer material exhibits a trade-off between toughness and stiffness, therefore, it remains difficult to develop a strategy that simultaneously realizes improved mechanical strength and toughness. Inspired by the bamboo-like structure, an efficient and simple melt sequential injection molding is proposed to fabricate a controllable skincore structure of iPP samples with self-reinforcement and t...

An Alternating Skin–Core Structure in Melt Multi-Injection-Molded Polyethylene
Shish-kebab, which is endowed with superior strength and modulus,
provides the potential to fabricate self-reinforced polymer products. However,
the injection-molded product usually exhibits a typical skin–core structure,
and the shish-kebab is only located in an extremely thin shear layer. Therefore,
the controlling and tailoring of crystal structures in complex flow field to
im...

Morphological comparison of isotactic polypropylene molded by water-assisted and conventional injection molding
Journal of Materials Science，2011，46（24）：7830~7838
It is well known that water-assisted injection molding (WAIM) process can be fulfilled based on the melt filling stage of conventional injection molding (CIM) process. However, due to the different physical fields involved during WAIM and CIM processes, WAIM part should exhibit unique morphological feat...

Crystalline Structure of Injection Molded β-Isotactic Polypropylene: Analysis of the Oriented Shear Zone
Although both shear flow and β-nucleating agent (β-NA) could separately induce β-crystal in isotactic
polypropylene (iPP), their combination, particularly in the typical industrial processes, in fact has received comparatively little
attention. In the current study, two-dimensional wide-angle X-ray diffraction and small-angle X-ray scattering (2D-WAXD/
SAXS) measurements were performed to inves...

Pre-shear induced anomalous distribution of β-form in injection molded iPP
On the laboratory scale, pre-shear induced orientation at high temperature can considerably
influence the subsequent crystallization, which has been intensively investigated by
various sophisticated methods. Unfortunately, during conventional polymer processing
(e.g., injection molding), the preservation of pre-shear induced orientation is a practical
challenge because oriented chains are pron...
