Application of Non‐Isothermal Network Theory With Curved‐Channel Element Characteristics to Predict Melt Conveying in High‐Performance Single‐Screw Extruders

open access: yesJournal of Polymer Science, EarlyView.
This study presents a fast and accurate calculation tool to predict conveying of polymer melts in single‐screw extruders. Integrating generalized sub‐models into network theory allows to represent the complex screw shapes and material behavior more realistically. Tests on an industrial extruder show close agreement with experiments, outperforming older

Conjugated Polymers Engineered for Flexible/Stretchable Electronics

open access: yesJournal of Polymer Science, EarlyView.
This review highlights glass transition temperature (Tg) as the central parameter linking molecular structure to device performance in conjugated polymers. By tuning backbone rigidity, side‐chain architecture, and dynamic bonding, Tg governs the balance between π–π stacking–enabled charge transport and mechanical compliance.

Electrically responsive knitted liquid crystal elastomer actuators for underwater applications

open access: yesResponsive Materials, EarlyView.
A knitted liquid crystal elastomer‐liquid metal (LM) actuator enables electrically driven soft robotics in water. Core–shell fibers are melt‐spun, knitted, and infused with LM to combine internal conductivity, external insulation, and programmable textile deformation.

Enhanced Actuation Stability of Liquid Crystal Elastomer Actuators With Diels–Alder Dynamic Bonds

open access: yesSmall, EarlyView.
By leveraging furan substitution, enhanced thermal stability during actuation of liquid crystal elastomers (LCEs) with Diels–Alder dynamic (DA) bonds was achieved. This work demonstrates that 3‐substituted furan broadens the actuation window of LCEs with DA bonds and enables superior thermomechanical stability and cycling performance at elevated ...
