During the last decade, major efforts have been made to develop adequate and commercially viable processes for disintegrating cellulose fibres into their structural components. Homogenisation of cellulose fibres has been one of the principal applied procedures. Homogenisation has produced materials which may be inhomogeneous, containing fibres, fibres fragments, fibrillar fines and nanofibrils. The material has been denominated microfibrillated cellulose (MFC). In addition, terms relating to the nano-scale have been given to the MFC material. Several modern and high-tech nano-applications have been envisaged for MFC. However, is MFC a nano-structure? It is concluded that MFC materials may be composed of (1) nanofibrils, (2) fibrillar fines, (3) fibre fragments and (4) fibres. This implies that MFC is not necessarily synonymous with nanofibrils, microfibrils or any other cellulose nano-structure. However, properly produced MFC materials contain nano-structures as a main component, i.e. nanofibrils.
在过去十年中，人们付出了巨大努力来开发适当且具有商业可行性的方法，将纤维素纤维分解成其结构成分。纤维素纤维的均质化一直是主要应用的方法之一。均质化产生的材料可能是不均匀的，包含纤维、纤维碎片、纤维状细粉和纳米纤维。这种材料被称为微纤化纤维素（MFC）。此外，与纳米尺度相关的术语也被用于MFC材料。人们设想了MFC的几种现代高科技纳米应用。然而，MFC是一种纳米结构吗？得出的结论是，MFC材料可能由（1）纳米纤维、（2）纤维状细粉、（3）纤维碎片和（4）纤维组成。这意味着MFC不一定与纳米纤维、微纤维或任何其他纤维素纳米结构同义。然而，正确生产的MFC材料包含纳米结构作为主要成分，即纳米纤维。
