Short for Polyhedral Oligomeric Silsesquioxanes Nanotechnology. POSS nanomaterials are attractive for missile and satellite launch rocket applications because they offer effective protection from collisions with space debris and the extreme thermal environments of deep space and atmospheric re-entry. Another application of POSS nanotechnology under development is a new high-temperature lubricant. This new nanolubricant is effective at temperatures up to 500Æ’F, which is 100Æ’F greater than conventional lubricants.
