제목 Fabrication of Nano Porous Silica Aerogel-Polydimethylsiloxane (PDMS) Insulation Film
초록 The silica aerogel is a suitable material to apply for insulation material with lower thermal conductivity than that of air to save energy. However expensive precursor and drying process were the main issues of the silica aerogel synthesis. Therefore, we demonstrate an eco-friendly route toward silica–PDMS insulation film with low thermal conductivity under ambient pressure. Silica aerogel was synthesized from rice husk ash, which was an agricultural waste to be able to recycle. The silica aerogel is prepared by sol-gel processing and obtained by modification of silica hydrogel surface and dry at ambient pressure. Finally, aerogel film was respectively fabricated by the different content with aerogel in PDMS. Silica aerogel particle size was analyzed by Scanning electron microscope and silica aerogel with high surface area (832.26 m²/g) was characterized by Brunauer Emmett Teller. Then thermal conductivity of silica Aerogel–PDMS insulation film was analyzed by thermal wave system.
