Silica aerogel(SA) has many unique propoerties such as large surface area, low density, low thermal conductivity. Yet, SA has also characteristic, mechanical weakness. This trait makes SA hard to apply industrial field. To improve this property, many researcher apply materials such as polymer, textile to synthesis step of SA. In this study, Polyethyleneimine is appllied to SA synthesis. SA is charaterized by FT-IR, NMR, BET for synthesis, surface area respectively. This work was supported by a grant (10080492) from Korea Ministry of Trade, Industry and Energy (MOTIE), Republic of Korea. |
