Abstract: A method for the preparation of high strength air-dried organic aerogels. The method involves the sol-gel polymerization of organic gel precursors, such as resorcinol with formaldehyde (RF) in aqueous solvents with R/C ratios greater than about 1000 and R/F ratios less than about 1:2.1. Using a procedure analogous to the preparation of resorcinol-formaldehyde (RF) aerogels, this approach generates wet gels that can be air dried at ambient temperatures and pressures. The method significantly reduces the time and/or energy required to produce a dried aerogel compared to conventional methods using either supercritical solvent extraction. The air dried gel exhibits typically less than 5% shrinkage.

Abstract: A method for forming a region of low dielectric constant nanoporous material is disclosed. In one embodiment, the present method includes the step of preparing a microemulsion. The method of the present embodiment then recites applying the microemulsion to a surface above which it is desired to form a region of low dielectric constant nanoporous material. Next, the present method recites subjecting the microemulsion, which has been applied to the surface, to a thermal process such that the region of low dielectric constant nanoporous material is formed above the surface.

Abstract: Stable high internal phase water-in-oil emulsions containing polymerizable vinyl monomers, crosslinking monomers and initiators are obtained, useful in producing low density porous crosslinked polymeric materials by using a surfactant system containing (a) an anionic surfactant, the anionic surfactant having an oil soluble tail and an anionic functional group and (b) one or more quatemary salts having one or more hydrocarbon groups having greater than or equal to 8 carbon atoms. A water-in-oil emulsion can be formed with lower surfactant concentration than sorbitan fatty acid ester alone and improved surfactant performance at elevated temperatures is obtained.

Abstract: Normally hydrophobic foams, such as polyurethane foams and polymerized water-in-oil emulsion foams, are rendered hydrophilic by means of treatment with sorbitan monolaurate. Thus, a polymeric foam can be prepared or treated with sorbitan monolaurate and thereafter dried to leave a substantially uniformly distributed residue of sorbitan monolaurate on the internal foam surfaces. The resulting treated foams are rendered hydrophilic and are thus suitable for use in absorbent devices, including diapers, sanitary napkins, bandages, and the like.
