Preparation of silica aerogel using urea as a template |
| 초록 |
Silica aerogels were prepared by sol-gel method using urea as a template. Formic acid was added to the mixture of urea solution and tetramethylorthosilicate (TMOS) to provide acidic condition. Prepared hydrogels were aged at an ambient temperature and pressure to obtain aerogels. Silica aerogels were obtained successfully by simple extraction of urea with water without adopting the supercritical drying process. The pore structure of aerogels can be controlled by varying the molar ratio of urea and TMOS. The prepared silica aerogels have surface area ranging from 700 to 970 m2 g-1. |
