Can Elastomers Combine Stiffness, Toughness and Fatigue Resistance?

open access: yesAdvanced Materials, EarlyView.
This review studies how the molecular and macroscopic architecture of elastomers influence their mechanical properties including: stiffness, stretchability, toughness, fatigue resistance, and damping behavior. By linking the structure to performance, it proposes design principles for advanced elastomeric systems that combine mechanical properties ...

Sustainable and Multifunctional Natural Macromolecular Polymers for Aqueous Zn Metal Batteries

open access: yesAdvanced Materials, EarlyView.
We comprehensively review the structure‐function relationships and regulatory mechanism of natural macromolecular polymers in stabilizing zinc anodes at the microscopic and mesoscopic scales. The interactions among polymer structures, optimization strategies, and regulatory mechanisms are discussed systematically summarizing recent related research ...

Polymer composites containing diatomite and boron carbide that are capable to absorb thermal neutrons

open access: yesХімія, фізика та технологія поверхні
Composites capable to absorb thermal neutrons have been developed on the basis of resol type matrix-bisphenol-formaldehyde oligomers, in which thermally modified natural sorbents - diatomite and boron carbide were used as fillers. In particular, we used

Soft Yet Tough Tanglemers Through Rapid Photopolymerization for DLP 3D Printing

open access: yesAdvanced Materials, EarlyView.
Soft yet tough tanglemers are produced through low‐initiator free radical photopolymerization and translated to DLP 3D printing. Systematic control over light intensity, initiator loading, and crosslink density reveals processing windows that balance printability, elasticity, toughness, and feature fidelity. ABSTRACT Additive manufacturing of compliant

Metastable Polymers for Circular 3D Printing

open access: yesAdvanced Materials, EarlyView.
3D‐printed polymers are usually permanent and hard to recycle. Here, metastable polymers are designed to fall apart on demand. A chemical trigger unzips the printed material back into its original building blocks within minutes at room temperature.

Electropolymerized Aptasensor for Femtogram‐Level Cytokine Detection

open access: yesAdvanced Materials, EarlyView.
Electropolymerization of 3‐amino‐ʟ‐tyrosine creates ultrathin, smooth, and chemically robust pALT nanofilms with accessible carboxyl functionalities for direct aptamer immobilization. Integrated with fiber‐optic SPR and OECT platforms, these interfaces enable IL‐6 detection down to 100 fg mL−1 and provide a versatile route to bioelectronic sensing ...
