Polycarbonate Vitrimers and Dynamic Co‐Networks From Epoxide/Carbon Dioxide Copolymerization

Macromolecular Rapid Communications, EarlyView.
This work demonstrates how CO2‐derived poly(propylene carbonate) and poly(cyclohexene carbonate) backbones influence vitrimer thermo‐mechanical behavior. By tuning backbone composition, epoxide crosslinker chemistry and blend ratios, the crosslinked materials span a wide property window, from highly extensible to stiff, glassy networks, establishing an

Role of 1D and 2D Materials in Achieving Transparent and Flexible Lithium‐Ion Batteries for Wearable Electronics

Small, EarlyView.
Hybrid 1D–2D architectures redefine material design strategies for TFLIBs by decoupling competing performance parameters. This approach accelerates the transition of TFLIBs from proof of concept to practical wearable technologies. ABSTRACT Transparent and flexible lithium‐ion batteries (TFLIBs), enabled by advanced nanomaterials and flexible ...

Multi‐Scale 3D Printing of Magnetic Polymer Nanocomposites with Controlled Particle Dispersion and Hyperthermic Response

Small, EarlyView.
Dispersion of magnetic nanoflowers in trimethylolpropane ethoxylate triacrylate to generate photocurable nanocomposites is described. Particle dispersion provides processability and target AC‐field stimulated temperature increases. Complex (DLP) printed structures with submicron features are demonstrated, and the potential for stimulated release of ...

Highly Efficient and Cytocompatible Panchromatic Photoinitiators for Photopolymerization and High‐Resolution 3D Printing beyond 450 nm

Small, EarlyView.
Phenothiazine photoinitiators P1 and P2 exhibit panchromatic photoinitiation through efficient SET with iodonium salts. P2 enables rapid red‐light polymerization, while both systems perform under sunlight and smartphone light. P1 supports 460 nm DLP 3D printing and shows lower cytotoxicity than TPO, offering safer photoinitiators for high‐precision ...

Beyond HEMA: Shifts in the (Meth)acrylate Composition of Matched Nail Cosmetics Between 2023 and 2026

Contact Dermatitis, EarlyView.
In 127 matched nail cosmetics, 2‐hydroxyethyl methacrylate (HEMA) and Di‐HEMA trimethylhexyl dicarbamate (Di‐HEMA TMHDC) listings decreased by approximately 75% between 2023 and 2026. Several other (meth)acrylate‐related ingredients also showed substantial increases or decreases.
