Abstract
To solve the difficult recycling and poor durability of puncture-resistant soft composites, this study proposed a synergistic reinforcement of hydrogel/aramid composites by dual nanomicelle cross-linked networks using Pluronic F127DA, TiN, and TiO2 nanoparticles. The TiN nanoparticles, a photothermal conversion material, were introduced into the gel system as toughening particles, and then they were synergized with the micellar state of Pluronic F127DA to form the core–shell structure nanomicelles, which provide more crosslink points and form a triple physical crosslink network with TiO2 NPs. This synergistic reinforcement had a significant effect on the mechanical properties of the gel matrix (302.27 MJ toughness), self-repair ability (100% under near-infrared light for 5 min), and the amazing improvement of the puncture resistance of the composites (276.78 N cone puncture resistance value, 241.98 N knife puncture resistance value). This study provides an important reference for the design of soft composites with both efficient self-healing properties and high puncture resistance.
期刊介绍:
Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field.
The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest.
Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials.
Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
