Polymers for Advanced Technologies, Volume 37, Issue 2, February 2026.ABSTRACT High‐resolution, biocompatible scaffolds are essential for reproducible tissue engineering and remain challenging to fabricate with vat photopolymerization due to cure‐depth control and limited bioactivity of neat polymers. This work investigated the mechanical, surface, and biological properties, as well as the high‐resolution 3D printability,

Journal of Applied Polymer Science, Volume 143, Issue 1, January 5, 2026.This study investigates the thermo‐electro‐mechanical properties of thermoplastic/epoxy blends as polymer hosts for composite polymer electrolytes. Blending PEO, PVA, and PVAc with heat‐resistant epoxy via suitable solvents yields films with high ionic conductivity and improved thermo‐mechanical stability, making them promising candidates for use in ...

Hierarchical Twist: Chirality Across Scales in Cellulose Cholesterics
Advanced Optical Materials, Volume 14, Issue 4, 27 January 2026.Hierarchical left‐ and right‐handed chiral nematic structures are observed in a solvent‐free thermotropic cellulose derivative. Free‐standing films show hierarchical twisted structures whose pitches respond differently to uniaxial strain: left‐handed pitches increase, ones decrease.
