摘要

尽管环氧树脂复合材料应用广泛，但要解决实际工程应用中脆性高和耐磨性差的缺陷，仍然是一项巨大的挑战。纳米材料可增强环氧基体材料的断裂韧性，并提供优异的抗摩擦性和耐磨性。在这项工作中，通过溶液浸渍和水热原位生长工艺，设计出了具有三维分层和 "砂浆砖 "多孔结构的晚期 ANFs/MXene/UiO-66-NH2 混合气凝胶（AMU）。由于氢键作用和静电吸附，MXene 和 UiO-66-NH2 被均匀地锚定在 ANFs 气凝胶骨架的表面。由于环氧树脂基体内部形成了高效的三维网络导热通道，所获得的 AMU-EP 复合材料具有优异的导热性。此外，在摩擦过程中，AMU 成分的高效协同作用在钢球表面形成了一层高质量的转移膜，这对提高 AMU-EP 的摩擦学性能非常重要。

An ultra-low density and mechanically robust ANFs/MXene/UiO-66-NH2 aerogel for enhancing thermal conductivity and tribological properties of epoxy resins

Despite epoxy composites being used in a wide range of applications, it remains a great challenge to solve the defect of high brittleness and poor wear resistance for real engineering applications. Nanomaterials enhance fracture toughness and provide superior antifriction and wear resistance for epoxy matrix materials. In this work, a late-model ANFs/MXene/UiO-66-NH₂ hybrid aerogel (AMU) with 3D layered and “mortar-brick” multi-hole structure was devised via solution impregnation and hydrothermal in situ growth processes. MXene and UiO-66-NH₂ were uniformly anchored to the surface of the ANFs aerogel backbone due to hydrogen bonding forces and electrostatic adsorption. The acquired AMU-EP composites exhibited excellent thermal conductivity owing to an efficient three-dimensional network of thermal conductive pathways inside the epoxy matrix. Moreover, the efficient synergistic effect of AMU components formed a high-quality transfer film on the surface of steel balls during the friction process, which was important for enhancing the tribological properties of AMU-EP.

期刊介绍： Composites Communications (Compos. Commun.) is a peer-reviewed journal publishing short communications and letters on the latest advances in composites science and technology. With a rapid review and publication process, its goal is to disseminate new knowledge promptly within the composites community. The journal welcomes manuscripts presenting creative concepts and new findings in design, state-of-the-art approaches in processing, synthesis, characterization, and mechanics modeling. In addition to traditional fiber-/particulate-reinforced engineering composites, it encourages submissions on composites with exceptional physical, mechanical, and fracture properties, as well as those with unique functions and significant application potential. This includes biomimetic and bio-inspired composites for biomedical applications, functional nano-composites for thermal management and energy applications, and composites designed for extreme service environments.
