Depending on the PE density and the branching rate of its polymer chains, we can distinguish different types of PE [146,147]: • Ultra-high-molecular-weight polyethylene (UHMWPE): It has a very high molecular weight. It is involved in fabrication of fibers with a tensile strength higher ...

High molecular weight ensures high network modulus and thus prema- ture failure of a sample could be precluded. Similar to the explanations used in tensile tests, the chain entan- glement density is also the major parameter in under- standing the impact toughness of polyethylene.18,19 Though ...
Over-all, these findings demonstrate that shear flow(high deformation) and dynamic rheology (smalldeformation) are complementary experimentaltools for the evaluation of the cloud point tem-perature in shear conditions.4CONCLUSIONAn extensive investigation of the rheologicalproperties of poly(ethylene oxide...

The LS detector was a Wyatt Technology High Temperature Dawn Heleos. The molecular weight, M, at each point in the chromatogram was determined by analyzing the LS output using the Zimm model for static light scattering (W. Burchard & W. Ritchering, “Dynamic Light Scattering from Polymer Solut...
The non-equilibrium stress-temperature phase diagrams are intrinsically different from equilibrium pressure-temperature phase diagram of PE. Uniaxial stress of around 3 MPa is sufficient to induce the formation of H-crystal, while more than 300 MPa of high pressure is required24. The two orders...
The reversible transitions among the four phases with stress hysteresis create a rich pool of kinetic pathways for FIC, which are expected to serve as a detailed roadmap for precisely processing of PE with designed structures and morphologies. Methods Material. High density polyethylene (HDPE) ...

At high loading of ETPTA, the surface morphologies of PEO−BSPE become rougher and more uneven due to the presence of particles. This ultimately leads to the formation of cracks and stratification, which negatively impacts the performance of LIBs. Conclusively, a sophisticated SPE should possess ...
