Schematic diagram of the slip-coating process and thin-film delamination by adhesive tape. (1) Polymer solution is applied to a glass slide substrate. (2) Polymer solution is evenly spread by slip-coating. (3) Evaporation. (4) In an optional step, analyte solution is cast upon the polymer-on-glass substrate. (5) Adhesive tape is applied to the perimeter of the polymer film; both are delaminated together from the substrate with a peeling motion. (6) This yields the freestanding thin film. |
