Title:
化学修飾されたセルロース微細繊維を含む高耐熱性樹脂複合体
Document Type and Number:
Japanese Patent JP7239524
Kind Code:
B2
Abstract:
Provided is a resin composite having high mechanical properties which make the resin composite moldable into and usable as members for use in applications such as vehicle-mounted members and electrical materials. The resin composite comprises 0.5-40 mass% chemically modified, fine cellulose fibers and a resin, wherein the chemically modified, fine cellulose fibers have a pyrolysis initiation temperature (TD) of 270°C or higher, a number-average fiber diameter of 10 nm or larger but less than 1 µm, and a degree of crystallinity of 60% or higher. In a preferred embodiment, the chemically modified, fine cellulose fibers have a coefficient of variation (CV) in DS unevenness ratio, DSs/DSt, of 50% or less, the DS unevenness ratio being the ratio of the modification degree (DSs) of the surface layers of the fibers to the modification degree (DSt) of the whole of the fibers.
