Fabrication of Free-Standing Gelatin Thin Films via the Gelation and Drying of Liquid Foam Films.

ABSTRACT: Ultrathin foam films can be prepared from numerous compounds under a wide range of conditions but have a narrow application scope because of their small size, susceptibility to rupture, and other drawbacks arising from low mechanical stability of the bilayer structure. To address this gap, we herein prepared ultrathin foam films of gelatin using a facile method via drying thin liquid films of aqueous gelatin solutions and the gelation. Their thickness ranges between nanometers to micrometers in response to changes in process parameters. The effects of various process parameters, including the solution concentration, frame size, drying temperature, and humidity, were systematically investigated. In addition to surface tension affecting the initial formation of the liquid film, the high visc
