Closed‐Loop and Sustainable 4D Printing of Multi‐Stimuli‐Responsive Sulfur‐Rich Polymer Composites for Autonomous Task Execution

Advanced Materials, EarlyView.
Closed‐loop and sustainable 4D printing of sulfur‐rich polymer composites is demonstrated for the first time using loosely crosslinked poly(phenylene polysulfide) networks (PSNs) and their magnetic composites (MPSNs). 3D‐printed PSNs and MPSNs exhibit shape‐morphing capabilities and can be directly reprinted into new form factors and magneto‐responsive

High‐Resolution Mechanoluminescent Haptic Sensor via Dual‐Functional Chromatic Filtration by a Conjugated Polymer Shell

Advanced Materials, EarlyView.
A high‐resolution mechanoluminescence (ML) platform is achieved through chromatic filtration strategy using a conjugated polymer shell (F8BT) on copper‐doped zinc sulfide microparticles. This shell narrows the emission bandwidth, selectively filtering out blue noise, while simultaneously boosting intensity via ML photon recycling process.
