METHOD FOR FORMING POLYMER COMPOSITE FILMS USING REMOVABLE SUBSTRATES

摘要

The invention is a method for forming polymer composite films using removable substrates by: (a) forming a first dispersion of a first perfluorinated polymer dispersed in a first dispersant; (b) depositing the first dispersion onto a first removable substrate; (c) removing the first dispersant from the first dispersion, thereby forming a first film; (d) forming a second dispersion of a second perfluorinated polymer disposed in a second dispersant; (e) depositing the second dispersion onto a second removable substrate; (f) removing the second dispersant from the second dispersion, thereby forming a second film; (g) bonding the first film to the second film; and (h) removing the first and the second substrate. The most preferred first and second dispersant is 1,2-dibromotetrafluoroethane.
