纤维素纳米纤维的应用研究--功能型添加剂的开发

Efforts for the practical use of cellulose nanofibers——The development of functional additives

日本制纸股份有限公司,属复合型生物质行业,充分利用木质生物资源,努力拓展各种新兴事业。当前致力于纤维素新用途之一纤维素纳米纤维(CNF)各种应用产品的生产和研发。该公司利用C NF高纤维强度和低热膨胀率,开发功能型纳米复合材料(与树脂和橡胶等);利用其高透明度,开发光学薄膜;利用其高比表面积,开发催化剂载体和吸收剂。在这些应用中,该公司的C NF作为功能型添加剂,例如增稠剂或分散剂,类似于现在使用的羧甲基纤维素(CMC),希望尽早商业化。本文拟介绍作为各类功能型添加剂CNF的研发;CNF的生产方法及其实际应用的固化技术以及CNF作为添加剂的各种特性。

As a comprehensive biomass industry, Nippon Paper Industries Co., Ltd. tries to develop various new business areas making the most of woody biomass. As one of the new use of cellulose, the company focuses on production and development of various application of cellulose nanofibers（CNF）. The company examines the use of CNF not only for functioned nanocomposite （with resin or rubber etc.） utilizing its high fiber strength and low thermal expansion, also for an optical film utilizing its high transparency and for a catalyst carrier or the absorbent utilizing its high surface area. Among those uses, because the use of CNF as functional additives such as thickener or dispersant is a similar use as existing carboxymethyl cellulose （CMC）, early commercialization is expected. In this report, the company presents the development of CNF as functional additives. And the production method of CNF, the solidification technology for practical use and CNF＇s various characteristics as additives are reported.
