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

This invention provides novel ammonium and sulfonium sulfonate zwitterions and polymers derived therefrom for a variety of end-use applications.

This invention provides a simple, fast, economical and scalable method for making porous, light-weight hard materials, such as aerogels. The method involves the use of polymer-assisted rapid thermal annealing, eliminating uneconomical steps used in conventional methods such as long thermal treatments, etching, and freeze-drying.

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 new chemical compositions and methods for the preparation of adhesive materials with low flammability. The low flammability is due to newly invented organic/polymeric components used in the adhesive formulation, rather than through the addition of a conventional anti-flammable additives such as halogenated organic molecules or phosphorous-containing structures.

When commercially available polymer membranes are exposed to aqueous solutions of salt, emulsified oil droplets, and other particulate matter, their lifetime can decrease catastrophically due to reduction in flux as a result of membrane fouling. This technology provides a new class of graft copolymers capable of extending the lifespan and functionality of water purification membranes. As a membrane coating material, the graft copolymers have excellent hydrophilicity and anti-fouling properties. In addition, they contain UV-activatable functional groups to enable UV-crosslinking of the copolymers, both within the coating itself to impart structural stability and into the underlying membrane to promote strong adhesion. These graft copolymer coatings are highly effective in preventing fouling of water-filtration membranes, and in maintaining the flux levels necessary for efficient filtration. Unlike other coating materials, the anti-fouling graft copolymers do not delaminate from the membrane substrate.

This invention provides a new class of zwitterionic polymers that exhibit hydrophobic properties and are soluble in polar organic solvents, allowing for their use as novel polymeric surfactants, and as functional materials in other applications.

This invention provides inherently flame-resistant, branched deoxybenzoin polymers. Such polymers can be used as additives to impart flame-retardant properties to polymer blends, as well as to improve the processability of the polymer blends.
