Abstract: Asymmetric organic-inorganic films and methods for forming and using such films. For example, the films are used as membranes for selective separation applications. The methods combine co-assembly of block copolymer (BCP) and inorganic nanoparticles (NPs), such as, for example, titanium dioxide (TiO 2 ), with non-solvent induced phase separation. The resulting films exhibit structural asymmetry. For example, the films have a thin nanoporous surface layer on top of a macroporous finger-like support layer. Parameters that may dictate membrane morphology include the fraction of inorganic nanoparticles used and the length of time allowed for surface layer development. In filtration tests, the resulting membranes show both desirable selectivity and permeability. The synthesis methods for hybrid membranes provide a new self-assembly platform upon which multi-functional and high-performance organic-inorganic membranes can be formed.

Abstract: A process for forming polymer powders by dissolving one or more polymers in a suitable solvent, followed by atomizing the solution into a droplet atmosphere of a non-solvent to precipitate polymer particles. The particles are separated from the non-solvent, washed and dried to produce a powder with a rounded particle morphology, high internal porosity and surface area, and high apparent density. Polymer powders with these properties can be pressed to dense shaped articles suitable for sintering in automated presses because the powders have good low and compressibility characteristics. The process if particularly useful when applied to soluble polymers that are not readily shaped by melt processing means.

Abstract: Porous cross-linked polyimide-urea networks are provided. The networks comprise a subunit comprising two anhydride end-capped polyamic acid oligomers in direct connection via a urea linkage. The oligomers (a) each comprise a repeating unit of a dianhydride and a diamine and a terminal anhydride group and (b) are formulated with 2 to 15 of the repeating units. The subunit was formed by reaction of the diamine and a diisocyanate to form a diamine-urea linkage-diamine group, followed by reaction of the diamine-urea linkage-diamine group with the dianhydride and the diamine to form the subunit. The subunit has been cross-linked via a cross-linking agent, comprising three or more amine groups, at a balanced stoichiometry of the amine groups to the terminal anhydride groups. The subunit has been chemically imidized to yield the porous cross-linked polyimide-urea network. Also provided are wet gels, aerogels, and thin films comprising the networks, and methods of making the networks.
