4D Printable Formulations of Mixed Low and High Molecular Weight Liquid Crystalline Units: A Versatile Route to Functional Soft Actuators

Macromolecular Rapid Communications, EarlyView.
This work presents a practical approach for formulating 4D printable inks that incorporates substantial fractions of low molecular weight mesogens. By blending low molecular weight diacrylate or monoacrylate constituents with a high molecular weight main‐chain macromer, the resulting mixture proves suitable for direct ink writing, enabling mechanical ...

Disulfide‐Induced Inhibition of Epoxy Cationic Photopolymerization: A Route to Maskless Patterning

Macromolecular Rapid Communications, EarlyView.
This study investigates the role of disulfide‐containing molecules on the photopolymerization of epoxy monomers through cationic ring‐opening reaction, with the demonstration of the selective inhibition of the polymerization when disulfides are added to the photocurable formulation. This quenching is then exploited as a novel maskless photolithographic

Diverse reactivity of maleimides in polymer science and beyond

Polymer International, Volume 74, Issue 4, Page 296-306, April 2025.
This mini‐review provides a thorough overview of maleimide chemistry, highlighting its diverse reactivity in polymer and materials science applications. Abstract Maleimides are remarkably versatile functional groups, capable of participating in homo‐ and copolymerizations, Diels–Alder and (photo)cycloadditions, Michael additions, and other reactions ...
