The reducing agent is included in an amount sufficient to react with the oxide to significantly increase a conductivity of a metal film that is formable from the nanoparticle dispersion using a deposition and heating process compared with the conductivity of a metal film formable from the same nanoparticle composition without the reducing agent using the same deposition and heating process. Methods for making the metal nanoparticle dispersion, as well as for making a film from the dispersion, are also disclosed. | 12-25-2014 |
20150053961 | ELECTRONIC DEVICE - An electronic device, such as a thin-film transistor, includes a semiconducting layer formed from a semiconductor composition. The semiconductor composition comprises a polymer binder and a small molecule semiconductor. The semiconducting layer has been deposited on an alignment layer that has been aligned in the direction between the source and drain electrodes. The resulting device has increased charge carrier mobility. | 02-26-2015 |
20150086805 | METHOD FOR FORMING METAL STRUCTURES - A method of forming a metal structure. The method comprises providing a dispersion of metal nanoparticles and a solution comprising a transient polymer and solvent. The dispersion of metal nanoparticles and the solution are formed by coaxially electrospinning into a fiber comprising the metal nanoparticles and the transient polymer. The fiber is heated to decompose the transient polymer and form a metallic structure. | 03-26-2015 |
