“…Perhaps the most common surface modifications intend to overcome the hydrophilic nature of CNMs in order to disperse them in hydrophobic polymer matrices. A wide variety of modifications have been reported, e.g., silanization, 233 transesterification, 234 vinyl esterification, 235 carbodiimide, 236 ATRP, 237 grafting from ring opening polymerization (ROP), 238 and many others, as summarized in recent reviews . 12,13,239 There is an old saying that it takes 10 min to make a polymer (or graft to one), but 10 months to characterize it.…”

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.

“…A lot of research output has shown enhanced biodegradation for a number of polymer matrices when cellulosic fibers are added to them [174,175]. However, the surface modification of the cellulose fibers negatively influences the matrix degradation because it reduces the number of OH group on the cellulose surface and so decreases the hydrophilicity [176]. Pinheiro and co-workers prepared poly (butylene adipate-co-terephthalate) PBAT-based composites with modified and unmodified cellulose fibers [174].…”

Fiber-matrix interaction at the interphase is one very important property that is of great concern to all polymer scientists involved in polymer composites. Many of the failures can be traced to the type of interfacial interaction existing in the composites. That is why highlighting the factors that dictate the type of and the extent of interactions at the interphases become very necessary. Natural fiber polymer composites have found application in many fields of human endeavors. To continue this growth being experienced, the factors that determine the formation of good interaction at the interphase most be understood, so that they can be manipulated for a better result.

“…Chemical modifications of CNC can be divided in three different groups: (i) in the presence of surface native functional groups, (ii) adsorption of functional groups, and (iii) covalently attached molecules . Several examples of chemical modifications of CNC have been extensively reviewed elsewhere . A comparison of some chemical modification methods is shown here.…”

This review describes the use of cellulose nanocrystals (CNC) as fillers in biodegradable polymer matrices over the past few years. The preparation and characterization of CNC‐based nanocomposites are highlighted here with a focus on thermophysical and mechanical properties. The characterization and isolation of nanocellulose from different raw material sources are discussed in detail, as well as different surface modifications. The addition of CNC in biodegradable polymer, combined with nanocellulose surface engineering and driven by sustainability trends, has the potential to impact various industrial sectors. POLYM.
