Semicrystalline polymers products usually adopt a crystallized form in their end-use
environment. These crystallized polymers undergo various deformations under different …

The stretch-induced structural evolution mechanism is a long-standing scientific question in
the post-stretching processing of polymer films. X-ray scattering, especially a combination of …

A universal method for determining the modulus of the interlamellar amorphous phase of
semicrystalline polymers was proposed. The basics of the method were presented on the …

Semicrystalline polymers with bimodal molecular weight distribution (MWD) have captured
broad interest in academia and industry. Current efforts to understand the effect of bimodal …

A class of innovative artificial muscles made of high-strength polymeric fibers such as fishing
lines or sewing threads have been discovered recently. These muscles are fabricated by a …

Ultra-high molecular weight polyethylene (UHMWPE) had been widely discussed in terms of
mechanical and wear-resisting performance, and gradually expanded to other functional …

Using the newly developed positron annihilation lifetime spectroscopy (PALS) facility with a
high count rate up to 3000 cps, in situ PALS experiments were performed for the first time on …

In this paper, for the first time, positron annihilation lifetime spectroscopy, after an
appropriate adaptation, was used to analyze the plastic deformation process of high-density …

The structure-property relationship of the interlamellar amorphous phase in semicrystalline
polymers has been a fundamental yet controversial topic in polymer physics for several …

In-situ small-and wide-angle X-ray scattering (SAXS/WAXS) is employed to study the stretch-
induced structural evolutions of four different pre-oriented isotactic polypropylene (iPP) cast …
