Abstract:

<p>The behaviour of a <i>p</i>-xylene-based lyophobic nanoporous carbon system under high hydrostatic pressures is investigated. As the pressure is increased to a critical value, the nanopore surfaces between graphene layers are exposed to the liquid phase, leading to a considerable increase in solidâ-“liquid interfacial energy. During unloading, defiltration does not occur until the pressure is much lower. Thus, the system is energy absorbing. Owing to the large solidâ-“liquid contact area, the energy absorption efficiency is much higher than that of conventional dampers.</p>
