Article Synopsis
- Creating safer secondary explosives that can be directly initiated by lasers is important, but it's tough to do without using sensitive primers.
- Researchers developed spherical composites of CL-20, enhanced with nano aluminum and a graphene-based catalyst, to improve laser absorbance and reduce mechanical sensitivity.
- These composites showed significantly higher critical impact energy and friction load, as well as improved laser absorbance in the near-infrared range, making them more effective for ignition with lower power lasers.
Various methods have been exploited to replicate nacre features into artificial structural materials with impressive structural and mechanical similarity. However, it is still very challenging to produce nacre-mimetics in three-dimensional bulk form, especially for further scale-up. Herein, we demonstrate that large-sized, three-dimensional bulk artificial nacre with comprehensive mimicry of the hierarchical structures and the toughening mechanisms of natural nacre can be facilely fabricated via a bottom-up assembly process based on laminating pre-fabricated two-dimensional nacre-mimetic films.
