High-performance mechanical energy absorption is pursued to protect personnel and important infrastructures and devices. Current energy absorption materials rely on processes like plastic deformation, cell buckling, and viscoelastic dissipation, but they face challenges in obtaining high energy absorption density and reusability. Fundamentally new mechanisms to absorb mechanical energy are being developed. This talk will discuss some latest developments of energy absorption materials by focusing on nanoporous materials. For example, the forced intrusion of liquid water and aqueous solutions in hydrophobic nanoporous materials such as zeolites and metal-organic frameworks (MOFs) presents an attractive pathway to engineering new energy absorption systems: substantial mechanical energy can be absorbed by generating huge liquid-solid interfaces in the nanopores. Such process can provide highly efficient and reusable impact protection at practically relevant high loading rate conditions. Some discussions on other energy absorption mechanisms or materials will also be included in this talk.
