有機－無機ハイブリッドガスバリア膜の開発

摘要

Recently, organic-inorganic hybrid films have been developed for gas barrier application. The gas barrier property of the films is an important factor for their application as packaging materials and electronics devices. A large variety of organic-inorganic hybrids prepared by sol-gel method and clay/polymer hybrids have been reported thus far. Incorporation of inorganic elements at the molecular level in organic polymers has resulted in novel properties such as improved gas barrier ability, mechanical, strength and thermal stability.rnIn this paper, I wish to introduce gas barrier properties of silica/poly (vinyl alcohol) and clay, poly (methyl methacrylate) organic-inorganic hybrid gas barrier films.%「有機－無機ハイブリッド材料」は，その材料のもつ可能性から近年，注目されている材料の一つである。文部科学省の第3期科学技術基本計画の重点推進4分野のナノテクノロジー・材料に含まれ，経済産業省策定の技術戦略マップ2010中にも随所に見られ，また，現在政府が進める「グリーン・イノベーション」でも取り上げられており，国内外で活発に研究開発が進められている。
