Infiltration of liquid metals in a nanoporous carbon

“…Previous experimental data have validated that they can be used to produce high-energy-density NEAS. [12][13][14] One problem of nanoporous carbon based NEAS is that, because the carbon phase and the liquid phase are often of different mass densities, the carbon particles may not be stably suspended. Shortly after an NEAS is placed at rest, the lightweight carbon particles can float on the surface, and the system becomes heterogeneous.…”

As the outer surface of a nanoporous carbon is treated with 16-mercaptohexadecanoic acid, the carbon particles can form a stable suspension in water. When the water phase is compressed, the liquid infiltration behavior in the nanopores becomes significantly different from that of untreated material, suggesting that the inner surface is also modified. After the treatment, the infiltration pressure does not decrease. Therefore, the surface-chain configurations at the inner and outer surfaces must be different, which explains the variations in infiltration pressure and volume.

The absorption of mechanical energy is becoming a promising application of MOF materials, which is important to the protection from damages and injuries associated with mechanical impact, vibration, or explosion. MOFs can absorb energy through solid–liquid interaction in nanopores or framework deformation under mechanical pressure. Energy absorption through these mechanisms can be amplified by the high surface area and porosity of MOFs and achieve a higher energy density than conventional energy absorption materials. For example, the pressurised intrusion of a non-wetting liquid into MOF nanopores can absorb impact energy by generating a large solid–liquid interface, and the structural transition or plastic deformation of MOFs can also be exploited for energy absorption under extreme conditions. This chapter provides an overview of these energy absorption mechanisms and the performance of different materials, connecting the fundamental science of MOF mechanics to practical engineering solutions.
