- sol-gel process;
- thermal barrier
The sol-gel process has been used to deposit thin films from solutions onto substrates of various geometries, both rigid and flexible. These alkoxide-derived solutions adhere to organic as well as inorganic substrates. The outcome of the sol-gel process in all cases is a microporous oxide. In the dried condition, the microporosity is open and accessible. When hermeticity is desired the porosity can be eliminated by proper heat treatment. Otherwise the porosity remains open and can be adjusted to create coatings with the properties of a thermal barrier, a separation medium or a chemical sensor.
