Fabrication of Large-area Free-standing Ultrathin Polymer Films.

摘要: This procedure describes a method for the fabrication of large-area and ultrathin free-standing polymer films. Typically, films are prepared using either sacrificial layers, which may damage film or affect its mechanical properties, they made on freshly cleaved mica, substrate that is difficult to scale. Further, size typically limited few square millimeters. In this method, we modify surface with polyelectrolyte alters strength adhesion between deposition substrate. The can be shown remain wafer spectroscopy, treated used produce multiple films, indicating at best minimal amounts added film. process has thus far been in scalability only by coating equipment, expected readily scalable industrial processes. study, protocol making solutions, preparing surface, producing described.
