Advantages of Bio- Inspired Coatings Over Traditional Solutions

Superior Lubrication in Diverse Environments

Conventional oil - or graase- based smarants lose effectivenes at high temperatures, under vacuum, or in corrisive environments. Bio- inspired coatings excel in conditions where liquid smarants fail.
