Polymeric Ammonium Halides to Tune Color Polymer-Perovskite Nanocrystal Composites
This invention demonstrates the leveraging of an ammonium halide-containing copolymer or a guanidium halide-containing copolymer to color tune lead halide perovskite nanocrystals (NCs). These multifunctional ligands boost the photoluminescence quantum yield and facilitate a route to control inter-NC halide exchange kinetics based on binding of the polymer chains to the NC surface and their solvent-responsive aggregation.

Soft and Stretchable Dielectric with Reliable Electrical Performance
This invention demonstrates a stretchable form of dielectric that maintains its electrical performance even in highly conductive environments for an extended period of time. This is achieved by embedding a layer of liquid metal in the soft and stretchable dielectric materials to effectively stop the diffusions of conductive matters diffusing/penetrating through the polymeric matrix network while maintaining the stretchability.

Reactive Particles for Cold Spray Coatings
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.
