Journal ArticleDOI
Multiscale and Multistep Ordering of Flow-Induced Nucleation of Polymers.
TL;DR: This review mainly summarizes experimental results, advances in physical understanding, and discussions on the multiscale and multistep nature of oriented nuclei induced by strong flow.
Journal ArticleDOI
Extension-Induced Nucleation under Near-Equilibrium Conditions: The Mechanism on the Transition from Point Nucleus to Shish
Dong Liu,Nan Tian,Ningdong Huang,Kunpeng Cui,Zhen Wang,Tingting Hu,Haoran Yang,Xiangyang Li,Liangbin Li +8 more
TL;DR: In this article, a modified stretched network model was employed to analyze strain-temperature equivalence on nucleation in FIC, which reveals that flow not only induces entropic reduction of initial melt, but also modifies the free energies of the final states.
Journal ArticleDOI
Correlation between Flow-Induced Nucleation Morphologies and Strain in Polyethylene: From Uncorrelated Oriented Point-Nuclei, Scaffold-Network, and Microshish to Shish
TL;DR: In this paper, an extension-induced crystallization of lightly cross-linked high density polyethylene (XL-HDPE) has been studied with a combination of extensional rheology and in situ synchrotron radiation small-angle X-ray scattering (SR-SAXS) measurements.
Journal ArticleDOI
Nonequilibrium Nature of Flow-Induced Nucleation in Isotactic Polypropylene
Kunpeng Cui,Dong Liu,Youxin Ji,Ningdong Huang,Zhe Ma,Zhen Wang,Fei Lv,Haoran Yang,Liangbin Li +8 more
TL;DR: In this paper, an in situ investigation on FIC under strong flow by combining a unique homemade extensional rheometer and ultrafast X-ray scattering reveals a constant critical strain or time for nucleation in isotactic polypropylene melt in a wide temperature range from 130 to 170 °C.
Journal ArticleDOI
Kinetic Process of Shish Formation: From Stretched Network to Stabilized Nuclei
Kunpeng Cui,Zhe Ma,Zhen Wang,Youxin Ji,Dong Liu,Ningdong Huang,Liang Chen,Wenhua Zhang,Liangbin Li +8 more
TL;DR: In this paper, a real-time investigation on flow-induced crystallization (FIC) of polyethylene bimodal blends was performed by combing a unique homemade extensional rheometer and synchrotron radiation small-angle X-ray scattering.
