Spinodal Decomposition in a Binary Polymer Mixture: Dynamic Self Consistent Field Theory and Monte Carlo Simulations

, 2001
We investigate how the dynamics of a single chain influences the kinetics of early stage phase separation in a symmetric binary polymer mixture. We consider quenches from the disordered phase into the region of spinodal instability. On a mean field level

Stretchable p/n‐Pair Thermoelectric Fibers Based on Core (Ag)–Shell (Ag2Se) Structure for Wearable Electronics

Advanced Functional Materials, EarlyView.
Stretchable p/n‐pair Ag@Ag2Se TE fibers are developed for next‐generation fiber‐based electronics. The TE fibers maintain excellent electrical conductivity and a high Seebeck coefficient under strain. Integrated into textiles, they enable simultaneous temperature and strain sensing, as well as energy harvesting, offering great potential for ...

Adaptive 4D‐Printed Vascular Stents With Low‐Temperature‐Activated and Intelligent Deployment

Advanced Functional Materials, EarlyView.
Microarchitected coronary artery stents were fabricated using a polycaprolactone (PCL)‐based shape memory polymer (SMP) composite via projection micro‐stereolithography (PµSL) 4D printing. By incorporating diethyl phthalate (DEP) as a plasticizer, the thermal transition temperature (Ttran) was modulated to about 37°C, enabling rapid and autonomous ...

Dual‐Functional Li2B4O7 Coating on Carbon Fibers for Enhanced Li+ Transport and Stability in Sulfide All‐Solid‐State Batteries

Advanced Functional Materials, EarlyView.
A dual‐functional Li2B4O7 coating on carbon fibers is designed to resolve the critical interfacial degradation in sulfide all‐solid‐state batteries. The conformal layer acts as a physical barrier to suppress parasitic reactions while its unique dielectric properties simultaneously facilitate Li+ transport.

Intermixing‐Driven Growth of Highly Oriented Indium Phosphide on Black Phosphorus

Advanced Functional Materials, EarlyView.
This study demonstrates controlled intermixing and compound formation at the In/black phosphorus (BP) interface, leading to highly oriented InP formation. Comprehensive structural and electrical analyses reveal tunable bandgap behavior governed by competing BP thinning and charge‐transfer effects, underscoring the critical role of interfacial compound ...
