Interest in nanofibrillated cellulose (NFC) has increased notably over recent decades. This bio-based nanomaterial has been used essentially in bionanocomposites or in paper thanks to its high mechanical reinforcement ability or barrier property respectively. Its nano-scale dimensions and its capacity to form a strong entangled nanoporous network have encouraged the emergence of new high-value applications. It is worth noting that chemical surface modification of this material can be a key factor to achieve a better compatibility with matrices. In order to increase the compatibility in different matrices or to add new functions, surface chemical modification of NFC appears to be the prior choice to conserve its intrinsic nanofibre properties. In this review, the authors have proposed for the first time an overview of all chemical grafting strategies used to date on nanofibrillated cellulose with focus on surface modification such as physical adsorption, molecular grafting or polymer grafting.
近几十年来，人们对纳米原纤化纤维素（NFC）的兴趣显著增加。这种生物基纳米材料由于其分别具有高机械增强能力或阻隔性能，已主要用于生物纳米复合材料或纸张中。其纳米级尺寸以及形成强缠结纳米多孔网络的能力，促使了新的高价值应用的出现。值得注意的是，这种材料的化学表面改性可能是实现与基体更好相容性的关键因素。为了提高在不同基体中的相容性或添加新功能，NFC的表面化学改性似乎是保留其固有纳米纤维特性的首要选择。在这篇综述中，作者首次概述了迄今为止用于纳米原纤化纤维素的所有化学接枝策略，重点关注表面改性，如物理吸附、分子接枝或聚合物接枝。
