My goal is to create a layer of Lead Zirconate Titanate, or other piezoelectric material, deposited on the surface of a PFTE Teflon tube. What are some good methods to accomplish this task?
If the PTFE tube is quite large (more than 30mm in diameter) then you can try applying the ceramic layer by plasma spraying. It's not easy, but possible.
To have adhesiveness, Plz, clean polymer surface thoroughly and treat it with oxygen plasma. may resolve your issue or can use above suggested method and experiment it.
