Abstract: A semicrystalline polyarylethersulfone (PAES) useful for additive manufacturing may be made by a method comprising: dissolving an amorphous polyarylethersulfone in a polar aprotic halogenated hydrocarbon solvent at a temperature adequate to effectively form a solution, and subsequently and spontaneously bring about reprecipitation of a semicrystalline polyarylethersulfone from the solution. The semicrystalline polyarylethersulfone may have a crystallinity of at least 30% by weight. The semicrystalline PAES, upon being heated, melting and uniting together in layers during additive manufacturing cools without substantially recrystallizing, allows for deformation-free articles to be formed having low residual stress.

Abstract: An example a method of manufacturing a film is provided. The method involves dissolving a backbone material in a non-aqueous solvent to form a non-aqueous solution. The method further involves adding the non-aqueous solution to an aqueous solution to form a liquid-liquid interface and injecting a particulate proximate to the liquid-liquid interface the non-aqueous solution is then evaporated to form a film containing the particulate. The film may be used in devices such as sensor devices for detecting hydrocarbons.
