Thermally Induced Gelling Systems Based on Patchy Polymeric Micelles

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
A novel strategy to design thermally induced gelling systems with tunable material properties is reported. Polymeric mixed‐shell micelles displaying multiple thermosensitive patchy domains formed hydrogels by assembling into well‐entangled worm‐like network structures upon heating to body temperature. The patchy micelle design significantly affects the

Structurally Colored Physically Unclonable Functions with Ultra‐Rich and Stable Encoding Capacity

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
This study reports a design strategy for generating bright‐field resolvable physically unclonable functions with extremely rich encoding capacity coupled with outstanding thermal and chemical stability. The optical response emerges from thickness‐dependent structural color formation in ZnO features, which are fabricated by physical vapor deposition ...

Development of a Novel, All‐Aromatic High Tensile Modulus Liquid Crystalline Polyimide for Fused Filament Fabrication Applications

open access: yesAdvanced Functional Materials, EarlyView.
A novel, high tensile modulus, fully aromatic thermotropic liquid crystalline polyimide (LCPI) with better solvent resistance and thermal stability is synthesized. Tensile specimens are fabricated using both injection molding and FFF processes, accomplished via lower viscosity enabled by the LC phase.

Shear‐Induced Nematic Alignment in Polysulfone Melts

open access: yesAdvanced Functional Materials, EarlyView.
Shear‐induced alignment is investigated by means of rheology and birefringence on an amorphous linear polysulfone melt. The absence of crystallization makes PSU particularly enabling to investigate temperature effects on the shear‐alignment of linear polymers, unveiling the role of chain relaxation times and possible enthalpic contributions.

Switching From Acceptor to FRET Donor: How the Organic Solar Cell Architecture Can Change the Role of a Chromophore

open access: yesAdvanced Functional Materials, EarlyView.
The non‐fullerene acceptor o‐IDT‐BT‐DCV is used in both binary and ternary blends to investigate the role that it plays in each device architecture. The charge generation pathways are found to differ between the binary and ternary blends with o‐IDT‐BT‐DCV becoming a second donor in the ternary blend.
