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.

Designing Thermally Stable DNA Hydrogels via Entropically‐Driven Acridine Intercalation

Macromolecular Rapid Communications, EarlyView.
Environmental variables are shown to systematically tune the network dynamics of entropy‐driven, acridine‐based DNA‐intercalating supramolecular hydrogels. Adjusting the buffer composition, ionic identity, and salt concentration impacts electrostatic screening and counterion release of the DNA backbone, offering a powerful handle to tune elasticity and

A Chemically Recyclable 1,3,5‐Triazine‐Based Epoxy Thermoset Enabled by Nucleophilic Aromatic Substitution Reaction

Macromolecular Rapid Communications, EarlyView.
High‐performance 1,3,5‐triazine epoxy networks are prepared via solvent‐free curing and recycled using nucleophilic aromatic substitution (SNAr) chemistry. This robust thermoset undergoes clean depolymerization into well‐defined building blocks for seamless repolymerization, achieving chemical recycling while preserving thermomechanical performance ...

Inferring Inter‐Well Fracture Interactions in Unconventional Reservoirs Using Fiber‐Optic Sensing and Coupled Multiphysics Modelling

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Integrating distributed temperature sensing (DTS) and distributed acoustic sensing (DAS) data with numerical simulations to analyze inter‐well interference and production responses remains challenging. This study employs a coupled thermal–hydraulic–mechanical simulation framework to model heat transfer, fluid flow, and geomechanical responses ...

Lichen‐Derived Mineral Residue as a Renewable Particulate Filler in Polylactic Acid Biocomposites: Structure, Melt Rheology, Viscoelastic, and Flexural Behavior

Polymer Composites, EarlyView.
Lichen residue, a renewable mineral‐organic material, was melt compounded with polylactic acid and triacetin in a twin‐screw extruder. ABSTRACT A lichen‐derived natural material, known as “höllük” in southeastern Turkey, is introduced as a renewable filler for polylactic acid (PLA).
