| 摘要 |
A process for the manufacture of micro or nanostructure surfaces or parts formed of PTFE by applying a vacuum to powered or granulated PTFE in a heated compression mold, applying a compression anvil within the metallic mold, removing the mold from the heating bath and quenching the mold to maintain pressure in the mold during a part of the quench. A mold or mold insert may be manufactured from sintered metal, a sintered ceramic of sintered stainless steel to allow the vacuum to be applied across a surface holding the micro or nanostructures.
