The Crystallization Behavior Regulating Nature of Hydrogen Bonds Interaction on Polyamide 6,6 by Poly(vinyl pyrrolidone)

Yang Liu et al.

Summary: The crystallization behavior of polyamide 6,6 (PA66) under complex flow field was studied with the addition of poly(vinyl pyrrolidone) (PVP) as a crystallization modifying agent. The regulation of hydrogen bonds interaction by PVP was investigated, and the microstructure evolution under external injection field was revealed. The changes in crystallization and microstructure during processing led to improved processability without sacrificing mechanical properties.

Dynamic Bonds Mediate π-π Interaction via Phase Locking Effect for Enhanced Heat Resistant Thermoplastic Polyurethane

Yue Lai et al.

Summary: Stimulus-responsive polymers with dynamic bonds exhibit self-healing, recycling and reprocessing properties due to enhanced relaxation of polymer chain with labile linkages. In this study, a new type of TPUs containing dynamic covalent bonds and pi-pi interaction in hard segments were investigated, indicating that TPUs with alkyl disulfide possess the maximum network relaxation time. The presence of disulfide bonds leads to stronger pi-pi stacking of aromatic rings, resulting in kinetically immobilizing the dynamic bond in TPUs.

Reversible-Irreversible Transition of Strain-Induced Crystallization in Segmented Copolymers: The Critical Strain and Chain Conformation

Ping Zhu et al.

Summary: The study investigated the formation, growth, and melting of SIC structures in PEBA elastomers using various spectroscopic and diffraction techniques. The findings showed that SIC can either fully melt or partially persist depending on the maximum strain applied before sample retraction. The research also improved the three-stage microscopic model for PEBA deformation by providing a detailed description of SIC behaviors at different stages of strain.

Wholly Biobased, Highly Stretchable, Hydrophobic, and Self-healing Thermoplastic Elastomer

Yeyen Nurhamiyah et al.

Summary: The wholly biobased, self-healing polyamide-based thermoplastic elastomer synthesized using a fatty dimer acid and a fatty dimer amine exhibits superior stretchability, high toughness, and excellent shape recovery. Its outstanding properties are attributed to the highly entangled main chain, multiple dangling chains, reversible physical bonds, intermolecular diffusion, and low ratio of amide to methylene group within the elastomer.

Dynamic Semi IPNs with Duple Dynamic Linkers: Self-Healing, Reprocessing, Welding, and Shape Memory Behaviors

Yanning Zeng et al.

Summary: This study presents a method for preparing recycled polymers with multiple dynamic linkers by introducing thermoplastic polyurethane into a linear copolymer and boronic ester crosslinker to form semi Interpenetrating Polymer Networks. The topologies of the recycled polymers can be altered due to the Diels-Alder reaction and transesterification of boronic ester bonds, resulting in good reprocessing and self-healing properties. Through a microinjection technique, the mechanical properties of the recycled samples can be well-restored after being reshaped at 190 degrees C for 5 minutes.
