Zentek updates on graphene-based icephobic technology for drones

Following its September 2022 announcement on testing of icephobic coating technology, Zentek has now reported successful drone testing, where thrust was maintained under calibrated icing conditions of freezing drizzle and freezing rain in an outdoor, real-world environment. The drone with Zentek's icephobic coating applied to the propeller blades hovered under the outdoor icing rig and, on all tests conducted, maintained flight until the end of the battery life of the drone. The same drone with uncoated propeller blades rapidly lost the ability to maintain flight, according to the Company.
