This invention demonstrates the use of polyelectrolyte complexes (PSS/PDADMAC) by leveraging the “saloplastic” properties as well as post-process annealing to fabricate sustainable, high-performance filtration membrane. This approach replaces traditional toxic organic solvents with water and salt, which does not only reduce environmental and health hazards but also simplifies the manufacturing process and cuts down on waste management costs.

This invention demonstrates formulations of nanocellulose to produce durable and high-performing anti-fogging coatings.  Nanoparticles such as silica and zinc can be added to include anti-scratch properties. The coatings are easy to produce, cost-effective and environmentally-friendly.

This invention demonstrates solid or semi-solid microparticles that undergo crosslinking and polymerization upon contacting a substrate to form a coating. The microparticles are maintained in an un-reacted state until delivered using cold spray processes where they are propelled using a gas stream at a pre-determined temperature and velocity. The process does not require volatile organic solvents or aqueous vehicles, nor plural component spray or two component formulations with limited shelf life but still deliver uniform coating.

This invention provides a novel method for the formation of graphene films, high-quality graphene films made thereby, and applications thereof.

This invention provides novel, deoxybenzoin-based anti-flammable polymers and cured epoxy resins for a variety of end-use applications.

New compositions of matter have been invented, specifically organic buffer layer materials that can greatly enhance power conversion efficiency (PCE) of organic photovoltaic (OPV) devices and can effectively functionalize metal electrodes. Conventional-architecture OPV devices made using the new buffer layer have average PCEs greater than 8%, with the highest PCE value exceeding 9.5%. This new buffer layer can be used with Ag, Cu, and Au cathodes, opening routes to all-solution-based device fabrication and roll-to-roll processing. In addition, the new buffer layer materials can be applied at a layer thickness of up to 55 nm, avoiding processing challenges that occur with ultrathin buffer layers and enabling a simplified and reproducible process for device fabrication.

This invention provides a new polymer processing technique, termed Melt-Mastication, which improves the properties of commodity semi-crystalline polymers, such as polypropylene. Compared with conventional methodology for processing polymers, Melt-Mastication creates unique microstructures in the polymer material, which results in improved mechanical and thermal properties of the polymer material and enables commodity polymers to compete with more costly materials in a variety of industries.
