Strain Hardening Behavior of Poly(vinyl alcohol)/Borate Hydrogels
The large-amplitude oscillatory shear (LAOS) behavior of poly(vinyl alcohol) (PVA)/borate hydrogels was investigated with the change of scanning frequency (ω) as well as concentrations of borate and PVA. The different types (Types I?IV) of LAOS behavior are successfully classified by the mean number of elastically active subchains per PVA chain ( feas) and Deborah number (De =...

Strain Hardening and Highly Resilient Hydrogels Crosslinked by Chain-Extended Reactive Pseudo-Polyrotaxane
Strain hardening and high resilience are two unique mechanical characteristics of many soft biological hydrogels. However, these properties, especially the strain hardening behaviour, are generally not seen in synthetic polymer hydrogels. Here, hydrogels are prepared by free-radical copolymerization of acrylamide and chain-extended vinyl-modified pseudo-polyrotaxane, which acts as a...

支化高分子溶液在剪切下的应力硬化
关键字:branch polymer, rheology, non-Gaussian stretching, strain hardening
We show for the first time that entangled polymeric liquids containing long-chain branching can exhibit strain hardening upon startup shear. As the significant long-chain branching impedes chain disentangle- ment, Gaussian coils between ent...

拉伸中应力硬化的本质:剪切与拉伸的区别
关键字:strain hardening, 应力硬化,线性高分子,支化高分子,拉伸
讨论拉伸中应力硬化出现的根本原因。 This work studies the origin of the so called "strain hardening" observed when comparing the transient stress response of entangled melts to uniaxial extension with that to simple shear. Strain hardening occurs...
