Abstract: In one or more embodiments, the present invention is directed to an electrically conductive polymer composition comprising a conductive metal filler material comprising a plurality of metal particles and one or more carbon-based filler material substantially homogenously dispersed throughout a polymer matrix, wherein the aspect ratio of the one or more carbon-based filler material is at least ten times greater than the aspect ratio of the conductive metal filler material comprising a plurality of metal particles. In one or more embodiment, the carbon-based filler material will comprise at least one of carbon nanotubes, multi-walled carbon nanotubes and edge-functionalized graphene.

Abstract: 3D printing filaments are described herein having core and shell thermoplastic extrudates. Each of the core and shell extrudates have glass transition temperatures, the glass transition temperature of the core being greater than or equal to the glass transition temperature of the shell. The ratio of the viscosity of the core thermoplastic extrudate at printing temperature, over the viscosity of the shell thermoplastic extrudate at printing temperature, is greater than 1, up to 20. The core and shell thermoplastic extrudates are miscible, or compatible with each other, or each comprise a polymer selected from the group consisting of polycarbonates, polyurethanes, polyesters, acrylonitrile butadiene styrene, styrene acrylonitrile, polyalkyl methacrylate, polystyrene, polysulfone, polylactic acid, polyetherimide, and polyimides.

Abstract: A nanoporous film formed from a series of vinyl addition block polymers derived from functionalized norbornene monomers are disclosed and claimed. The nanoporous films as disclosed herein are useful as pervaporation membranes and antireflective coatings among various other uses. Also disclosed herein are the fabrication of nanoporous films into pervaporation membranes which exhibit unique separation properties, and their use in the separation of organic volatiles from biomass and/or organic waste, including butanol, phenol, and the like. The fabrication of nanoporous films into antireflective coatings are also disclosed.

Abstract: Solvent mixtures useful for processing bulk heterojunction materials and methods for selecting the same are disclosed, wherein Hansen solubility parameters are utilized to select the solvent mixture. A solvent system using a fully nonhalogenated solvent mixture is disclosed. Also disclosed is a solvent mixture containing 20 vol. % acetophenone (AP) in mesitylene (MS), wherein the performance of the solvent system is comparable to dichlorobenzene.

Abstract: The invention provides a method for the self-assembly of organometallics within a sacrificial amphiphilic template in order to produce uniform mesoporous carbon composites coated with the organometallic component.
