Abstract : Films and coatings are prepared from a dispersion of microscopic sheets of para ordered aromatic heterocyclic polymers by collecting the sheets from the dispersion either by filtration on a porous surface or by drawing a metal surface through the dispersion, and allowing the dispersion medium to evaporate. Upon drying the microscopic sheets coalesce to form the films or coatings. This procedure makes possible the fabrication of high quality, thermally stable films and coatings without the use of high temperature cures or other severe conditions. (Author)
