Crystallization and Motility-Induced Phase Separation in the Flow of Active Brownian Particles Around an Obstacle [PDF]

EPJ Web of Conferences
The interaction between fluid flow and obstacles is a fundamental problem in fluid dynamics, exemplified by the Kármán vortex street and its Reynolds number-dependent instabilities.

Effect of pre-shear on flow-induced crystallization of branched polypropylene

, 2023
In this work, the effect of pre-shearing time on the crystallization of long-chain branched polypropylene (LCB-PP) subjected to simultaneous cooling and shearing was investigated using a polarized optical microscope equipped with a parallel-plate shear ...

Flow-Induced Crystallization of Crosslinked Poly(vinylidene fluoride) at Elevated Temperatures: Formation and Evolution of the Electroactive β‑Phase

, 2020
Flow-induced crystallization of poly­(vinylidene fluoride) (PVDF) was investigated for a broad temperature range from 160 to 220 °C by in situ synchrotron wide-angle X-ray diffraction (WAXD) and small-angle X-ray scattering (SAXS).

Experiments and analysis of stress-induced stiffening of a polypropylene [PDF]

Polyolefins Journal
Describing the solidification process is very important in polymer processing. In polypropylene (PP), the increase of viscosity, named stiffening or hardening, is determined by a rise in crystallinity.

Modelling flow induced crystallization of IPP: Multiple crystal phases and morphologies

Polymer, 2019
Being able to properly model the material structure formation during processing is a fundamental step to predict final product properties, especially for semicrystalline polymers, like isotactic PolyPropylene (iPP), which can develop a multiplicity of different crystalline phases and morphologies.

Review on the properties and mechanisms of asphalt modified with bio-oil and biochar

Journal of Road Engineering
Bio-asphalt has a great application prospect in the replacement of petroleum-based asphalt to pave and maintain asphalt pavement. However, the problems of flow-induced crystallization and phase separation caused by flow-induced crystallization had ...

The influence of grafting on flow-induced crystallization and rheological properties of poly(ε-caprolactone)/cellulose nanocrystal nanocomposites

Nanocomposites, 2018
The influence of poly(ε-caprolactone) (PCL) grafts on the rheology and crystallization behavior of nanocomposites based on PCL and cellulose nanocrystals (CNC) both under quiescent and shear conditions is investigated.

Micro-Mechanism Research into Molecular Chains Orientation Synergistically Induced by Carbon Nanotube and Shear Flow in Injection Molding

Applied Sciences, 2020
For the degree of orderly arrangement of the molecular chains at the interface of nanocomposites, the static and sheared polyethylene (PE)/carbon nanotube (CNT) models and the sheared pure PE model were constructed, and molecular simulation experiments ...

Squeeze flow induced crystallization monitoring in polymers

Polymer Testing, 2011
Abstract A rheo-optic set-up originally designed for applying a shear strain to the material (CSS450 from Linkam) was used to generate a squeeze flow and follow the subsequent crystallization of the polymer. A polypropylene was used as the test material. The squeeze was achieved using the gap control motor of a hot stage conventionally used for shear
