Microstructured ultrathin HDPE films prepared by selective oriented recrystallization

AbstractThe recrystallization behavior of surface-modified melt-drawn HDPE thin films having a vacuum-evaporated carbon layer was studied by means of transmission electron microscopy and electron diffraction. The results show that, by surface modification with the carbon layer, the orientation of the melt-drawn highly oriented HDPE film can be preserved after complete melting and subsequent recrystallization for any condition. Based on the orientation maintenance phenomenon of the carbon-coated preoriented HDPE films, micrometer-structured, thin HDPE films with well-defined oriented and nonoriented structures were prepared by selectively coating the melt-drawn-oriented HDPE thin film with the help of a micrometer-structured mask and subsequent melt recrystallization. A potential application of the thus prepared micrometer-structured HDPE thin films stems from the fact that they exhibit conspicuous different birefringence between the areas with and without carbon coating under polarized optical microscopy. This may provide us with a new route toward polarization-dependent displays.
