PTFE Nanocrystallines by Oriented Plasma Polymerization at Atmospheric Pressure

摘要

PTFE nano-crystallines with different morphology and crystal structures were rapidly formed by an Atmospheric Plasma Polymerization at room temperature without any catalysts or templates. Transmission electron microscopy (TEM) and X-ray diffraction (XRD) results indicated single crystal phase of the nano-crystallines. Other characterization methods, such as Polarization optical micrographs of the nanocrystallines at high temperatures showed their higher thermal stability compared to the PTFE bulk polymers. The atmospheric oriented plasma polymerization can serve as a common method for nanofabrication of many other single crystalline polymer systems.
