Initiated chemical vapor deposition (iCVD) is a novel process capable of producing a range of polymeric and multifunctional nanocoatings. Coatings can be made extremely thin (down to 10nm) on objects with dimensions in the nanometer range (e.g. carbon nanotubes). The process enables the deposition of true linear polymers, including those considered intractable to conventional thin coating, such as PTFE. Importantly, the object to be coated remains at room temperature, which means that nanothin coatings can be prepared on materials ranging from plastics to metals. The process is also conformal, which means it provides uniform coverage on objects which have small, complex, 3D geometries. A review of the process, its relevance to nanotechnology, and the applications currently being commercialized will be given.
