Title: Wataru Oka: Innovator in Transparent Hybrid Materials
Introduction
Wataru Oka is a notable inventor based in Kobe, Japan. He has made significant contributions to the field of transparent hybrid materials, holding a total of 2 patents. His work focuses on enhancing the properties of materials used in various optical applications.
Latest Patents
Oka's latest patents include a "Transparent Hybrid Sheet" and a "Transparent Composite Composition." The Transparent Hybrid Sheet is designed to possess superior transparency and thermal resistance, featuring a smaller linear expansion coefficient and reduced optical anisotropy. This innovation is achieved through a hybrid composition that includes an epoxy resin containing an alicyclic epoxy compound and a curing agent, along with a glass filler. The composition is carefully formulated to ensure that the amounts of isomers of the diepoxybicyclohexyl compound are kept to 20% or less.
The Transparent Composite Composition comprises an epoxy resin and a glass filler, where the epoxy resin includes at least one type with a lower refractive index and another with a higher refractive index than the glass filler. This unique combination results in a material that exhibits low linear expansion, excellent transparency, heat resistance, and solvent resistance. Such properties make it suitable for applications in liquid crystal display device substrates, organic EL device substrates, optical lenses, and more.
