The reason for the ongoing interest in this research field is that, analogue to the deposition of inorganic coatings by chemical vapor deposition, the deposition of polymer coatings from the vapor

Another example of polymers with low solubility are fluoropolymers. Christian and Coclite investigated the deposition of fluoroacrylate polymer

• deposition enables coatings of polymers that have only low levels of solubility in solvents. This highlights the importance of vapor deposition techniques in the field of conductive polymers, which are often insoluble and hard to process.

• solvent-based methods becomes considerably more challenging due to the lack of solubility in common commercial solvents, which limits processability and leads to poor wettability. These challenges can be overcome with oxidative chemical vapor deposition (oCVD). oCVD is a single step, solvent-free
