Highly oriented poly(tetrafluoroethylene) (PTFE) films were obtained by sliding a bar of a commercial grade PTFE along a strip of mica at a temperature of 300 degrees C. High resolution transmission electron microscopy was used to image the <10(1)over bar 0> lattice planes of the hexagonal phase IV in suitably oriented regions of the sample, indicating coherent order over distances of the order of at least 0.1 mu m both perpendicular and parallel to the chain axis.
