Silica aerogel is a nanostructured-porous materials with high surface area, high porosity. Due to this properties, it has a number of applications such as thermal insulator, acoustic absorbent, catalytic supports. However, silica aerogel generally have poor mechanical property and stability owing to its structure. Fiber-reinforced aerogel blanket is one of the most famous method to make aerogel composites. But this preparation method has poor dispersion of aerogel in the blanket. To improve the dispersity of aerogel in blanket, non-woven fiber and surface modified silica aerogel was dispersed in solution. Dispersity of aerogel in blanket, scanning electron microscope images was employed. |
