Highly oriented polytetrafluoroethylene (HOPTFE) was prepared by friction-transfer method on glass substrates under uniform deposition conditions. The distribution of finely divided HOPTFE macromolecular ridges was investigated by atomic force microscopy, pointing out that HOPTFE molecular films may induce topographically directed self-assembly processes. Furthermore, on the basis of their surface topographical features, the properties of HOPTFE ridges to act as templates for the alignment of gold nanoparticles are discussed. © 2009 IEEE NANO Organizers.

Abstract
Highly oriented polytetrafluoroethylene (HOPTFE) was prepared by friction-transfer method on glass substrates under uniform deposition conditions. The distribution of finely divided HOPTFE macromolecular ridges was investigated by atomic force microscopy, pointing out that HOPTFE molecular films may induce topographically directed self-assembly processes. Furthermore, on the basis of their surface topographical features, the properties of HOPTFE ridges to act as templates for the alignment of gold nanoparticles are discussed. © 2009 IEEE NANO Organizers.
