Polyethylene's and polypropylenes are most studied polymers by different solid-state NMR
methods. Among various NMR methodologies used, time-domain proton NMR (TD-NMR) …

Chain entanglements, which reside in the amorphous phase of semicrystalline polymers,
influence many macroscopic properties of polymers. There are different opinions about the …

There are long-standing debates in crystallization mechanism of polymer chains at the
molecular levels: Which comes first, chain folding or lamellae formation during …

Exploring the relationship between the polymer structure and property/function is a long-
lasting topic in polymer science since relevant research is critical for the rational design of …

This article presents a brief summary of the basic concepts of polymer crystallization. This is
a topic of great academic and practical interest. Polymer crystallization determines the …

The non-equilibrium thickness of lamellar crystals in semicrystalline polymers varies
significantly between different polymer systems and depends on the crystallization …

Semicrystalline polymers are categorized as either mobile or fixed crystals, depending on
chain mobility in the crystalline region. In this work, we investigate molecular dynamics and …

The structures of a single polyethylene chain were investigated using all-atom molecular
dynamics simulations with a series of cutoff distances. We found that a long single chain with …
