Abstract
Controlling the permeation of molecules and ions enables numerous technologies, including sensing, actuation, membrane separations, controlled drug release, and electrochemical energy storage. Rapid transport requires using ultrathin layers. Selective and switchable permeation entails the precise design of film architecture at the molecular level. Additionally, the permeation control layers must conform to the micro- and nanostructured topologies utilized to increase the surface area for permeation. This work will review the utility of highly conformal chemical vapor deposited (CVD) polymer nanolayers for permeation control. Using CVD polymerization couples the versatility of organic chemistry with the high-purity and systematic process control of all-dry vacuum processing. The full retention of organic functional groups by polymerization is essential for the fabrication of smart layers capable of switching permeation behavior in response to variations in light, pH, or temperature. Additionally, precise mechanistic control over chain formation and morphology is also essential for engineering the ionic conduction of vapor deposited polymer nanolayers.
