This communication summarizes the salient features and mechanisms in high-pressure homogenization of wood fibres in order to make nanofibrillar cellulose (NFC).

The energy-efficiency of delamination of fibres and the clogging tendency of fibres in high-pressure homogenizers/microfluidizers during delamination are critical and ways to alleviate these problems are reviewed.

It is shown that the mechanical properties of NFC-films can be estimated from the Page equation. Usually, the evolution of the tensile strength properties of NFC-films increases with the extent of film delamination to reach a saturation value, which can be deduced from first principles using the Page equation.

Finally, the evolution of the rheological features of NFC-gels and the barrier properties are reviewed and the estimation the nanofraction content in NFC-gels is being discussed.

该交流总结了木纤维高压均质化的显着特征和机理，以制造纳米原纤维纤维素（NFC）。

纤维分层的能量效率和分层过程中高压均质机/微流化器中纤维的堵塞趋势至关重要，因此对减轻这些问题的方法进行了综述。

结果表明，NFC薄膜的机械性能可以从Page方程中估算出来。通常，NFC薄膜的拉伸强度特性的演变会随着薄膜分层达到饱和值而增加，这可以使用Page方程从第一个原理推导出来。

最后，回顾了NFC凝胶的流变特性的演变和阻隔性能，并讨论了NFC凝胶中纳米级分含量的估计。
