At the MIT Institute for Soldier Nanotechnologies (ISN), Professor Karen Gleason works to find a way to coat fine objects. Researchers in her lab use a process called hot filament chemical vapor deposition (HFCVD) to deposit nanolayers of polytetrafluoroethylene (PTFE, also known as Teflon). In this video, Gleason explains this unique "waterproofing" technique and its numerous applications.
