Title: Naoya Okabayashi: Innovator in Laminate and Chemical Processes
Introduction
Naoya Okabayashi is a notable inventor based in Kawasaki, Japan. He has made significant contributions to the fields of materials science and chemical engineering. With a total of 2 patents, his work focuses on innovative solutions that address industry challenges.
Latest Patents
One of Okabayashi's latest patents is a laminate and process for producing the same. This invention relates to a laminate that changes dimensions minimally, preventing curling and warpage when ambient humidity fluctuates. It is particularly useful for flexible printed wiring boards. The laminate features a polyimide layer or layers formed on a conductor, with at least one layer composed of a low hygroscopic expansion polyimide. This polyimide is created through the reaction of diamines containing 20 mol % or more of 4,4'-diamino-2,2′-dimethylbiphenyl with a tetracarboxylic acid compound, exhibiting a coefficient of linear hygroscopic expansion of 15×10/% RH or less.
Another significant patent is the process for preparing 2,6-naphthalene-dicarboxylic acid. This process involves a reaction step where 2,6-naphthalene-dicarboxylic acid potassium salts react with benzene-carboxylic acids in the presence of water. This yields 2,6-naphthalene-dicarboxylic acid and benzene-carboxylic acid potassium salts. The subsequent separation step allows for the crystallization of 2,6-naphthalene-dicarboxylic acid, which serves as a low-cost raw material for polymers, while also enabling the recycling of potassium.
