Silica aerogel/unsaturated polyester composites were fabricated by room temperature forming of silica aerogel powders and unsaturated polyester resin. Due to the porous structure, silica aerogel showed extremely low thermal conductivity. But owing to the attraction of aerogel and polymer resin, aerogel pores isn’t preserved. Polymer resin tend to decrease of mobility at low temperature conditions. A new process was designed to preserve pores between hydrophobic silica aerogels and unsaturated polyester composites using room temperature forming. Well-preserved aerogel pores were observed in the silica aerogel/unsaturated polyester composites using scanning electron microscope and Heat insulation property was indicated thermal conductivity. And it was measured by the plating method. |
