Synergistic Network Formation in SBR/ANF Composites: GMA Bridging and Electron‐Beam Crosslinking for Enhanced Strength and Damping Control

Polymer Engineering &Science, EarlyView.
Styrene‐butadiene rubber/aramid nanofiber composites interfacially reinforced with glycidyl methacrylate via electron beam irradiation. ABSTRACT Styrene‐butadiene rubber (SBR) is widely used in tire and damping applications, yet its reinforcement with polar nanofillers is often limited by weak interfacial adhesion in nonpolar matrices.

Regioselective “hydroamination” of alk-3-ynones with non-symmetrical o-phenylenediamines. Synthesis of diversely substituted 3H-1,5-benzodiazepines via (Z)-3-amino-2-alkenones

, 2016
The reaction of alk-3-yn-1-ones (a bifunctional reagent) with o-phenylenediamines provides an effective synthetic method with high atom economy for the preparation of diversely substituted 1,5-3H-benzodiazepines.

Improve the Thermal Conductivity, Insulation Performance and Mechanical Properties of Silicone Rubber by Constructing EG‐PDA‐Cu Hybrid Nanoparticles

Journal of Polymer Science, EarlyView.
In this work, a novel expanded graphite‐supported nano‐copper polydopamine composite was designed and synthesized. The procedure involved first modifying EG via a mussel‐inspired technique to deposit a polydopamine coating, after which Cu2+ ions were reduced to immobilize copper nanoparticles onto the EG‐PDA substrate.

Mechanism of Antiozonant Action. I. Consumption of p-Phenylenediamines in Rubber Vulcanizates during Ozonization

, 1963
The consumption of N,N′-bis(1-methylheptyl)- and N-isopropyl-N′-phenyl-p- phenylenediamine in cis-polybutadiene vulcanizates was measured as a function of the ozonization time and the initial diamine concentration. The results are consistent with a rapid

Invisible near‐infrared thermo‐stimulated luminescence from carbon dots enabled by stepwise energy transfer for concealed information encryption

Responsive Materials, EarlyView.
A fully metal‐free near‐infrared (NIR) thermo‐stimulated luminescent system is developed by embedding carbon dots into a carbon nitride matrix and integrating multistage Förster resonance energy transfer. The system exhibits long‐term charge retention, rewritable optical memory, and highly concealed NIR readout, promising for secure data encryption and
