Three-dimensional Patterning Super-Black Silica-Based Nanocomposite Aerogels.

ABSTRACT: Aerogels are ultra-lightweight, porous materials defined by a complex network of interconnected pores and nanostructures, which effectively suppress heat transfer, making them exceptional for thermal insulation. Furthermore, their porous architecture can trap and scatter light via multiple internal reflections, extending the optical path within the material. When combined with suitable light-absorbing materials, this feature significantly enhances light absorption (darkness). To validate this concept, mesoporous silica aerogel particles were incorporated into a resorcinol-formaldehyde (RF) sol, and the silica-to-RF ratio was optimized to achieve uniform carbon compound coatings on the silica pore walls. Notably, increasing silica loading raised the sol viscosity, enabling formulations idea
