The article discusses the development of ultrastrong and tough gels through advanced mechanical training strategies. By incorporating dynamic interactions like hydrogen bonding and metal coordination bonds into molecular design, as well as introducing high-order structures, significant advancements have been made in improving the mechanical properties of synthetic elastomers and gels. The concept of mechanical training, inspired by muscle strengthening, involves force-induced self-reinforcement resulting in aligned nanofibrillar network architectures. Deep eutectic solvents (DES) are highlighted for their role in manipulating polymer networks, enabling self-healing properties and high temperature-resistance. The focus is on a high-efficiency mechanical training strategy using DES to create hyperhysteresis-mediated mechanical training, which enhances mechanical properties with only a single pre-stretch. This approach refines nanocrystals, increases hydrogen bond density, and provides structural retardation, leading to hierarchically-aligned nanofibrillar microstructures. The newly developed eutectogels, engineered through hyperhysteresis-mediated mechanical training, exhibit substantially improved modulus and strength compared to traditional polymer gels, showcasing convenient fabrication procedures and remarkable mechanical properties.
