Fumed silica nanoparticle coated with temperature-sensitive polymer |
| 초록 |
The nanoparticle composed of fumed silica and poly(N-isoprpylacrylamide)(PNIPAAm), which is temperature-sensitive, was prepared. The various particle sizes of fumed silica were used as the template for attaching PNIPAAm which was cross-liked with methylene bisacrylamide. The release behavior and particle size was investigated as a function of particle size of fumed silica and temperature of solution. Results revealed that the nanoparticle are thermo-sensitive and display a reversible swelling and de-swelling at the lower critical solution temperature. |
