Abstract:

The friction-deposited PTFE layers and their ability to act as orientation inducing substrates were fully characterized. The PTFE layers were studied by optical microscopy, scanning electron microscopy, atomic force microscopy, and by electron diffraction. Both the topology and the molecular structure were determined. The mechanism of mesoepitaxy was explored and clarified in detail through the use of overlayers. The mesoepitaxy technique was expanded from planar surfaces to the internal surfaces of polyethylene oriented by gel processing. There is serious interest by industry in using the PTFE layers for orientation. Areas of specific interest include polarizers for liquid crystal displays, and thin film transistors fabricated from oriented organic semiconductors. UNIAX Corp. Santa Barbara has taken an option on exclusive license on the technology and is working with several companies toward development of the technology. Mesoepitaxy, Gel-processing, Oriented polymers.
