A new family of materials comprised of cellulose, cellulose nanomaterials (CNMs), having properties and functionalities distinct from molecular cellulose and wood pulp, is being developed for applications that were once thought impossible for cellulosic materials. Commercialization, paralleled by research in this field, is fueled by the unique combination of characteristics, such as high on-axis stiffness, sustainability, scalability, and mechanical reinforcement of a wide variety of materials, leading to their utility across a broad spectrum of high-performance material applications. However, with this exponential growth in interest/activity, the development of measurement protocols necessary for consistent, reliable and accurate materials characterization has been outpaced. These protocols, developed in the broader research community, are critical for the advancement in understanding, process optimization, and utilization of CNMs in materials development. This review establishes detailed best practices, methods and techniques for characterizing CNM particle morphology, surface chemistry, surface charge, purity, crystallinity, rheological properties, mechanical properties, and toxicity for two distinct forms of CNMs: cellulose nanocrystals and cellulose nanofibrils.

纤维素纳米材料的当前表征方法

纤维素,纤维素纳米材料(CNMs)组成的新材料家族具有与分子纤维素和木浆不同的特性和功能,目前正在开发用于纤维素材料以前认为不可能的应用。商业化与该领域的研究并驾齐驱,其特征的独特组合助长了这些挑战,例如高轴向刚度,可持续性,可扩展性和对各种材料的机械加固,从而使其在广泛的高强度材料中得到了广泛应用。高性能材料的应用。然而,随着兴趣/活动的指数级增长,对于一致,可靠和准确的材料表征所必需的测量协议的开发已经赶不上了。这些协议是在更广泛的研究社区中开发的,对于在材料开发中提高对CNM的理解,工艺优化和利用至关重要。这篇综述建立了用于表征CNM颗粒形态,表面化学,表面电荷,纯度,结晶度,流变性质,机械性能和毒性的两种CNM两种不同形式的详细最佳实践,方法和技术:纤维素纳米晶体和纤维素纳米原纤维。
