Vanadium oxide for infrared coatings and methods thereof
| DWPI Title: Preparing crystalline vanadium oxide used as infrared polymer coatings, comprises providing vanadium oxide precursor comprising vanadium oxide particles, and annealing vanadium oxide particles at first oxygen partial pressure |
| Abstract: The present invention relates to vanadium oxide and methods of controlling reaction processes for making such materials (e.g., powders). In particular embodiments, the method includes control of oxygen partial pressure in order to kinetically control the oxidation species of the crystalline vanadium oxide material. Other methods, uses, systems, protocols, and coatings are also described. |
| Use: The method is useful for preparing crystalline vanadium oxide (claimed) which is used as infrared polymer coatings. |
| Advantage: The method has a simple, single annealing step (or heat treatment step) to obtain the desired material. |
| Novelty: Preparing (M1) crystalline vanadium oxide, comprises: (i) providing a vanadium oxide precursor comprising vanadium oxide particles; and (ii) annealing the vanadium oxide particles at a first oxygen partial pressure of 2-500 ppm, thus preparing the crystalline vanadium oxide in tetragonal form. |
