Macromolecular Rapid Communications, EarlyView.Liquid crystal elastomer (LCE) filaments are fabricated through extrusion with in‐process UV curing, enabling controlled flow alignment and network locking of mesogens. The resulting structure responds to thermal or optical stimuli, inducing molecular reorientation and macroscopic contraction.

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

Chemically and Mechanically Recyclable Polyolefins Incorporating Covalent Adaptable Networks
Macromolecular Rapid Communications, EarlyView.Low‐molecular‐weight polypropylene is converted into a crosslinked polyolefin containing a covalently adaptable network. The semicrystalline material remains melt‐processable and mechanically recyclable. Its thermal and mechanical properties are comparable to commercial polyolefins.

Reprocessable Disulfide‐Based Vitrimers with Adhesive Properties
Macromolecular Rapid Communications, EarlyView.A dual‐curing strategy combining UV‐induced thiol–ene polymerization and thermal thiol–epoxy curing was used to prepare disulfide‐based vitrimer networks with reprocessable, recyclable, and adhesive properties enabled by dynamic disulfide exchange. ABSTRACT A family of disulfide (S–S) containing thiol–vinyl–epoxy dynamic networks are presented.

Materials Genome Engineering Advances, EarlyView.Four constitutive models are evaluated for FeCoNiCr and Al0.6FeCoNiCr HEAs under wide temperature and strain‐rate conditions. The predictive capabilities and limitations of each model are then critically assessed, with particular emphasis on strain rate sensitivity, temperature dependence, and physically unrealistic responses at extreme loading ...
