Influence of Acrylonitrile Content on Processing, Morphology, Thermal Behavior, and Mechanical Properties of PA/NBR Thermoplastic Vulcanizates

Journal of Applied Polymer Science, Volume 143, Issue 11, March 15, 2026.
Influence of acrylonitrile (ACN) content on the processing behavior and morphological development of PA/NBR thermoplastic vulcanizates. Torque‐time profiles, SEM, and SEM/AFM images show that an intermediate ACN level (38%) promotes improved phase dispersion and morphological uniformity, especially with increased processing time, resulting in the most ...

Mechanical, Thermal, and Morphological Properties of PA/NBR TPVs: Influence of Processing Conditions and Recyclability

Journal of Applied Polymer Science, Volume 143, Issue 8, February 20, 2026.
Dynamic vulcanization at higher shear rates refines PA/NBR morphology, reduces domain size, and maintains mechanical performance after reprocessing. ABSTRACT Thermoplastic vulcanizates (TPVs) of polyamide 6 and nitrile butadiene rubber (PA/NBR) present excellent mechanical properties but traditionally suffer from performance loss during re‐melt ...

Ultrahigh‐Mass‐Loading Electrodes With Enhanced Homogeneity Using a High‐Concentration Slurry for Lithium‐Ion Batteries

Carbon Energy, Volume 8, Issue 1, January 2026.
Based on the integrated binder–CNT composite dispersion (IBC) solution, a high‐solids–content (77 wt%) slurry could be prepared. Using this slurry, an ultrahigh‐mass–loading cathode ( > 12 mAh/cm2) is demonstrated. The fabricated electrode showed a uniform CBD distribution from top to bottom, supporting the electrode's excellent mechanical properties ...

Chemical Prelithiation of Silicon Powder and its Role as Anode Material for All‐Solid‐State Batteries

Batteries &Supercaps, Volume 8, Issue 12, December 2025.
This article explores a carrier‐type approach for the chemical prelithiation of silicon (Si) powder and investigates the integration of prelithiated silicon (LixSi) as electrolyte‐free anode in sulfide‐based all‐solid‐state batteries. In comparison to a Si anode, the LixSi anodes showed improved cycle stability at 2 C, but revealed kinetic limitations ...

Magnetron reactively sputtered Ti-DLC coatings on HNBR rubber: The influence of substrate bias [PDF]

, 2008
In this study, Ti-containing diamond-like carbon (Ti-DLC) coatings have been deposited on HNBR (hydrogenated nitrile butadiene) rubber and also on Si wafer as reference via unbalanced magnetron reactive sputtering from a Ti target in C2H2/Ar plasma.
