Abstract
Deep eutectic solvents (DESs) are able to promote vulcanization and improve mechanical properties of rubber nanocomposites. Investigated are rheological and thermo-oxidative aging behaviors of carbon black (CB) filled natural rubber (NR) nanocomposites mediated by a developed DES, revealing that the presence of DES could significantly promote vulcanization of NR and dispersibility of CB, the latter being related to polar interactions between DES and CB. DES interferes with the Payne effect by improving the onset strain amplitude and weakening the storage modulus decay and the loss modulus overshoot in the nonlinear viscoelasticity region without influencing mechanisms of Mullins effect during cyclic uniaxial tension at large strains. During long-term thermo-oxidative aging, DES influences the evolutions of mechanical properties and Mullins effect depending on the composition. This work is helpful for mediating the CB dispersity, NR crosslinking, strain softening and thermal-oxidative aging behavior of NR nanocomposites for design and manufacture of high-performance products.
期刊介绍:
Composites Part A: Applied Science and Manufacturing is a comprehensive journal that publishes original research papers, review articles, case studies, short communications, and letters covering various aspects of composite materials science and technology. This includes fibrous and particulate reinforcements in polymeric, metallic, and ceramic matrices, as well as 'natural' composites like wood and biological materials. The journal addresses topics such as properties, design, and manufacture of reinforcing fibers and particles, novel architectures and concepts, multifunctional composites, advancements in fabrication and processing, manufacturing science, process modeling, experimental mechanics, microstructural characterization, interfaces, prediction and measurement of mechanical, physical, and chemical behavior, and performance in service. Additionally, articles on economic and commercial aspects, design, and case studies are welcomed. All submissions undergo rigorous peer review to ensure they contribute significantly and innovatively, maintaining high standards for content and presentation. The editorial team aims to expedite the review process for prompt publication.
