Patent number: 8927055Abstract: Coating compositions, and methods for depositing them on the surface of an article to produce an antireflection coating, are disclosed. In one embodiment, the coating composition includes a (meth)acrylate-functional silicon alkoxide, silica particles, a (meth)acrylate monomer, an epoxy (meth)acrylate oligomer, a photoinitiator, a solvent, an acid, and water. The relative amounts of these constituents are controlled such that, when the coating composition is deposited onto the surface of an article and cured, it has a refractive index less than about 1.60 at a wavelength of 510 nm. In another embodiment, the coating composition includes an organo-metallic compound other than an organo-metallic compound of silicon, an epoxy-functional silicon alkoxide, a non-epoxy-functional silicon alkoxide, a curing agent compatible with epoxy-functional molecules, a solvent, an inorganic acid, and water.Type: GrantFiled: June 19, 2009Date of Patent: January 6, 2015Assignee: Yazaki CorporationInventors: Yongan Yan, Satyabrata Raychaudhuri, Matthew Emilio Coda

Patent number: 8926853Abstract: Aspects of the invention are directed to a method of forming graphene structures. Initially, a cluster of particles is received. The cluster of particles comprises a plurality of particles with each particle in the plurality of particles contacting one or more other particles in the plurality of particles. Subsequently, one or more layers are deposited on the cluster of particles with the one or more layers comprising graphene. The plurality of particles are then etched away without substantially etching the deposited one or more layers. Lastly, the remaining one or more layers are dried. The resultant graphene structures are particularly resistant to the negative effects of aggregation and compaction.Type: GrantFiled: August 23, 2012Date of Patent: January 6, 2015Inventors: Xin Zhao, Yu-Ming Lin
