A present invention is directed to a laminated filtration media comprising a nanofiber coating applied onto a synthetic substrate. Generally, the laminated filtration media can be produced by applying the nanofiber layer onto the synthetic substrate via an electrospinning process and then thermo-mechanically bonding the nanofiber layer onto the synthetic substrate via a thermal bonding process. The laminated filtration media exhibits superior durability and can be used in a wide array of air filtration applications.

The present invention relates generally to compositions for use in biological and chemical separations, as well as other applications. More specifically, the present invention relates to hybrid felts fabricated from electrospun nanofibers with high permeance and high capacity. Such hybrid felts utilize derivatized cellulose, and at least one non-cellulose-based polymer that may be removed from the felt by subjecting it to moderately elevated temperatures and/or solvents capable of dissolving the non-cellulose-based polymer to leave behind a porous nanofiber felt having more uniform pore sizes and other enhanced properties when compared to single component nanofiber felts.

The invention provides novel polymer nanofiber or microfiber mats or membranes and methods for their preparation via an aqueous, one-step polyelectrolyte complexation and electrospinning of complex coacervates.

The invention relates to lithium-based battery systems and, more particularly, to electro-spinable solution compositions, electro-spun sulfur-polymer fibers, e.g., wires and yarns, and their use in preparing high performance sulfur mattes, e.g., electrodes, for lithium-sulfur batteries with potential applications in small-scale mobile devices. The sulfur-polymer fibers have nanoscale dimensions and yarn-like morphology. The sulfur-polymer fibers can be prepared by co-dissolving sulfur and polymer in a solvent for forming the electro-spinable solution, and electrospinning the solution. The electrospun fibers can be used to form a composite that includes alternating layers of the electrospun fibers and polymer on a current collector.

A method of manufacturing an elastic polymer aerogel material includes dissolving tire waste in a first portion of a solvent to form a first mixture; dissolving a polymer having at least one double carbon-carbon bond in a second portion of the solvent to form a second mixture; combining the first mixture and the second mixture, wherein the tire waste reacts with the polymer having at least one double carbon-carbon bond to form a reactant gel; and undergoing a solvent exchange on the reactant gel followed by freeze drying the reactant gel to form the elastic polymer aerogel material. The tire waste includes natural rubber, synthetic polymers, steel, and curing systems, and the elastic polymer aerogel material defines a 3D porous structure.
