摘要：

The incorporation of functionalized core-shell polymer nanoparticles in a silica network, by the sol-gel process, yields a structure stiff enough to withstand capillary pressure upon subcritical drying. The resulting hybrid aerogels are machinable monoliths, stable under atmospheric conditions, and have improved mechanical performance. These combined properties make them strong candidates for insulation in high value applications.
