20130225397 | Binderless Molecular Sieve Catalyst and a Preparation Method Thereof - The present invention relate to a binderless molecular sieve catalyst and a process for preparing the same, which are mainly useful for solving the problems of the current catalysts, such as lower activity, less pore volume and worse diffusivity. The present invention relates to a novel binderless molecular sieve catalyst, comprising, based on the weight of the catalyst, 90-100 wt. % of a molecular sieve, 0-10 wt. % of a binder, and 0-10 wt. % of an anti-wear agent, wherein said catalyst has a pore volume of 0.1-0.5 ml/g, an average pore diameter of 50-100 nm, and a porosity of 20-40%; the anti-wear agent is selected from the rod or needle-like inorganic materials having a length/diameter ratio of 2-20. Said catalyst has the advantages of higher activity, greater pore volume, larger average pore diameter and porosity, and better diffusivity, and well solves said problems and can be used for the industrial preparation of binderless molecular sieve catalysts. | 08-29-2013 |

20130342221 | METAL NANOSTRUCTURED NETWORKS AND TRANSPARENT CONDUCTIVE MATERIAL - Metal nanowires, such as silver nanowires coated on a substrate were sintered together to form fused metal nanowire networks that have greatly improved conductivity while maintaining good transparency and low haze. The method of forming such a fused metal nanowire networks are disclosed that involves exposure of metal nanowires to various fusing agents on a short timescale. The resulting sintered network can have a core-shell structure in which metal halide forms the shell. Additionally, effective methods are described for forming patterned structure with areas of sintered metal nanowire network with high conductivity and areas of un-sintered metal nanowires with low conductivity. The corresponding patterned films are also described. When formed into a film, materials comprising the metal nanowire network demonstrate low sheet resistance while maintaining desirably high levels of optical transparency with low haze, making them suitable for transparent electrode, touch sensors, and other electronic/optical device formation. | 12-26-2013 |
20140238833 | FUSED METAL NANOSTRUCTURED NETWORKS, FUSING SOLUTIONS WITH REDUCING AGENTS AND METHODS FOR FORMING METAL NETWORKS - Reduction/oxidation reagents have been found to be effective to chemically cure a sparse metal nanowire film into a fused metal nanostructured network through evidently a ripening type process. The resulting fused network can provide desirable low sheet resistances while maintaining good optical transparency. The transparent conductive films can be effectively applied as a single conductive ink or through sequential forming of a metal nanowire film with the subsequent addition of a fusing agent. The fused metal nanowire films can be effectively patterned, and the patterned films can be useful in devices, such as touch sensors. | 08-28-2014 |
20150144380 | TRANSPARENT CONDUCTIVE COATINGS BASED ON METAL NANOWIRES AND POLYMER BINDERS, SOLUTION PROCESSING THEREOF, AND PATTERNING APPROACHES - Polymer binders, e.g., crosslinked polymer binders, have been found to be an effective film component in creating high quality transparent electrically conductive coatings or films comprising metal nanostructured networks. The metal nanowire films can be effectively patterned and the patterning can be performed with a high degree of optical similarity between the distinct patterned regions. Metal nanostructured networks are formed through the fusing of the metal nanowires to form conductive networks. Methods for patterning include, for example, using crosslinking radiation to pattern crosslinking of the polymer binder. The application of a fusing solution to the patterned film can result in low resistance areas and electrically resistive areas. After fusing the network can provide desirable low sheet resistances while maintaining good optical transparency and low haze. A polymer overcoat can further stabilize conductive films and provide desirable optical effects. The patterned films can be useful in devices, such as touch sensors. | 05-28-2015 |
