発明の名称 (英語) MICROFIBRILLATED CELLULOSE HAVING CELLULOSE TYPE-II CRYSTALLINE STRUCTURE, AND MOLDED ARTICLE CONTAINING THE MICROFIBRILLATED CELLULOSE
発明の概要(英語) Although a microfibrillated cellulose has been conventionally added to a resin molded article for the purpose of improving the properties of a resin such as strength, it is only possible to achieve the same level of strength as that of the resin itself. The object is to provide a resin molded article having a higher strength. A molded article can be produced by blending a resin with a microfibrillated cellulose having a type-II crystalline structure produced by treating a microfibrillated cellulose with an alkali solution. The molded article can be largely increased in tensile strength or flexural strength, tensile strain at break or flexural strain at break, and fracture toughness (work-of-fracture) compared to a molded article produced with a resin containing a conventional microfibrillated cellulose.
