Nanofibrous network aerogels as an important class of porous material have received enormous attention in materials research. However, the fabrication of nanofibrous network aerogels with short fiber as building blocks is extremely challenging, since it is difficult for them to build 3D network structures spontaneously from the topological point of view. Here the synthesis and load transfer behavior of 3D aerogels composed of halloysite nanotube (HNT) short fibers are described. The resulting aerogels take inorganic materials as the skeleton, elastic organic materials as the connection point, and exhibit inorganic/organic phase interfaces. Confocal Raman microscopy system is utilized to investigate the structural‐dynamic profile of halloysite clay aerogels (HCAs) under applied load. The results indicate that the deformation mainly occurs in the polysiloxane (PSO) molecular chain connected with the HNT skeleton. HCAs have a certain load transfer capability, and the PSO chains between tubes are strong enough to support the HCA skeleton.

埃洛石纳米管制备的3D气凝胶的载荷传递行为

纳米纤维网络气凝胶作为一类重要的多孔材料在材料研究中受到了极大的关注。然而，以短纤维作为构建块的纳米纤维网络气凝胶的制造极具挑战性，因为从拓扑学的角度来看，它们很难自发地构建3D网络结构。在此描述了由埃洛石纳米管（HNT）短纤维组成的3D气凝胶的合成和载荷传递行为。所得的气凝胶以无机材料为骨架，弹性有机材料为连接点，并表现出无机/有机相界面。共焦拉曼显微镜系统用于研究在施加载荷的情况下埃洛石粘土气凝胶（HCA）的结构动力学轮廓。结果表明，变形主要发生在与HNT骨架连接的聚硅氧烷（PSO）分子链中。HCA具有一定的负载传递能力，并且管之间的PSO链足够坚固，可以支撑HCA骨架。
