This study employed the in-situ wide angle X-ray diffraction to explore the stretching-induced and relaxation-reversed phase transition in poly(butylene succinate) (PBS). It was found that relaxation was able to trigger the reversed β-α phase transition of PBS, where β phase completely transformed into α phase by partially unloading the stress.

A flexible, durable SERS substrate is fabricated via a “cut-and-paste” method using densely packed Au NPs on PDMS.

This study proposes a novel multiple dynamic pressure forming process. Cyclic pressure loading and unloading aligns solid-phase PLA molecular chains along the tensile direction, increasing ordered crystalline content and strengthening crystal-amorphous interphase connectivity, thereby enhancing mechanical strength and toughness of PLA.

A novel rotational shear system (RSS) was used to fabricate multi-layer self-reinforced HDPE pipes featuring alternating shish-kebab and spherulite structures. Controlled mandrel rotation and cooling aligned molecular chains to form high-strength structures. The annular tensile strength of the TSK pipe increased from 26.7 MPa to 76.3 MPa, a 185.8% enhancement. SKS tubes maintained excellent tensile strength (73.4 MPa) and achieved 50.1% elongation due to smaller shish-kebab crystals and reduced interlocking. This improvement is supported by 2D-SAXS analysis, which confirmed that crystal size and amorphous region thickness critically affect the mechanical performance of these multi-layer pipes.

Polydimethylsiloxane (PDMS)-based antifouling polymers with tunable self-healing capabilities in aqueous conditions were fabricated by incorporating amphiphilic segments and Fe³⁺–catechol coordination crosslinking.

The present work elucidates the laws governing the influence of chain defects and temperature on the nonlinear mechanical behavior of polyvinyl alcohol films. By analyzing the effect of chain defects (vinyl acetate units) on the crystallization behavior of poly(vinyl alcohol), an intrinsic mechanism that favors stretching-induced new crystal formation at high temperatures and low alcoholysis degree has been revealed.

This study introduces a unified framework for determining phase equilibria in multi-component polymer systems through effective chemical potentials. The ensemble-agnostic approach decouples free energy calculations from phase equilibrium computations, enabling direct solution of multiphase coexistence within the canonical ensemble while maintaining compatibility with existing SCFT solvers.

Based on dynamic Monte Carlo simulations, it was demonstrated that the SC fraction is closely correlated with the average mixing parameters during crystallization. In other words, the average segment miscibility in the crystallization process is the key factor controlling the formation ability of SCs.
