Abstract: A porous composition comprising a porous organic polymer (POP) fiber having a diameter of at least 100 nm and a length of at least 1 mm and pores having a size within a range of 10 nm to 5 microns distributed over the surface and volume of the POP fiber, wherein the organic polymer is insoluble in water and may be selected from, e.g., polyolefins, polyesters, polyamides, and polyacrylonitrile. Also described herein is a method for producing a POP fiber comprising: (i) forming a precursor fiber from a blend of an organic polymer and lignin, wherein the lignin is present in the form of domains within the precursor fiber; and (ii) washing the precursor fiber with a solvent that dissolves the lignin to result in the POP fiber. Also described herein is a method for removing oil from an oil-water mixture comprising contacting the oil-water mixture with the POP fibers.

Abstract: Methods of forming nanoporous materials are described herein that include forming a polymer network with a chemically removable portion. The chemically removable portion may be polycarbonate polymer that is removable on application of heat or exposure to a base, or a polyhexahydrotriazine (PHT) or polyhemiaminal (PHA) polymer that is removable on exposure to an acid. The method generally includes forming a reaction mixture comprising a formaldehyde, a solvent, a primary aromatic diamine, and a diamine having a primary amino group and a secondary amino group, the secondary amino group having a base-reactive substituent, and heating the reaction mixture to a temperature of between about 50 deg C. and about 150 deg C. to form a polymer. Removing any portion of the polymer results in formation of nanoscopic pores as polymer chains are decomposed, leaving pores in the polymer matrix.

Abstract: A first PECVD process incorporating a silicon oxide precursor alone and then with an organo-silicon precursor with increasing flow while the flow of the silicon oxide precursor is reduced to zero provides a graded carbon adhesion layer whereby the content of C increases with layer thickness and a second PECVD process incorporating an organo-silicon precursor including an organic porogen provides a multiphase ultra-low k dielectric. The multiphase ultra-low k PECVD process uses high frequency radio frequency power just above plasma initiation in a PECVD chamber. An energy post treatment is also provided. A porous SiCOH dielectric material having a k less than 2.7 and a modulus of elasticity greater than 7 GPa is formed.

Abstract: A method of efficiently removing a low molecular weight substance from a polyimide precursor or polyimide in which the low molecular weight substance is dispersed as micro-domains, without using a large amount of an organic solvent. The method of removing a low molecular weight substance comprises subjecting either a polymer composition having a micro-domain structure made up of a continuous phase comprising a polyimide precursor and, dispersed therein, a discontinuous phase comprising a low molecular weight substance or a polyimide composition obtained from the polymer composition by converting the polyimide precursor into a polyimide to extraction with a combination of supercritical carbon dioxide and a co-solvent to thereby remove the low molecular weight substance. The co-solvent is preferably an aprotic polar solvent, more preferably a nitrogen compound solvent or a sulfur compound solvent.

Abstract: Highly uniform microporous foam suitable for medical applications and methods for preparing these foams. The highly uniform microporous foams are of controlled pore size that may be utilized in a variety of applications. In preparing the foams, an organic crystalline polymer is melted and combined with a selected solid crystalline fugitive compound to produce a substantially isotropic solution. The solution is cooled under controlled conditions, which foster solid-solid phase separation by the simultaneous crystallization of the fugitive compound and the polymer, to produce a foam precursor containing the solidified fugitive compound dispersed through a matrix of the organic polymer. Crystals of fugitive compound are then removed by solvent extraction and/or sublimation, or like process to produce microcellular foams having a continuous, open-cell structure.
