Abstract

The cost-effective implementation of nanofibrillated cellulose (CNF) at industrial scale requires optimizing the quality of the nanofibers according to their final application. Therefore, a portfolio of CNFs with different qualities is necessary, as well as further knowledge about how to obtain each of the main qualities. This paper presents the influence of various production techniques on the morphological characteristics and properties of CNFs produced from a mixture of recycled fibers. Five different pretreatments have been investigated: a mechanical pretreatment (PFI refining), two enzymatic hydrolysis strategies, and TEMPO-mediated oxidation under two different NaClO concentrations. For each pretreatment, five high-pressure homogenization (HPH) conditions have been considered. Our results show that the pretreatment determines the yield and the potential of HPH to enhance fibrillation and, therefore, the final CNF properties. These results enable one to select the most effective production method with the highest yield of produced CNFs from recovered paper for the desired CNF quality in diverse applications.

摘要

在工业规模上经济高效地实施纳米原纤化纤维素（CNF）需要根据其最终应用优化纳米纤维的质量。因此，需要一系列不同质量的CNF，以及关于如何获得每种主要质量的更多知识。本文介绍了各种生产技术对由回收纤维混合物生产的CNF的形态特征和性能的影响。研究了五种不同的预处理方法：机械预处理（PFI磨浆）、两种酶水解策略以及在两种不同NaClO浓度下的TEMPO介导氧化。对于每种预处理方法，考虑了五种高压均质（HPH）条件。我们的结果表明，预处理决定了产率以及HPH增强原纤化的潜力，进而决定了最终的CNF性能。这些结果使人们能够从回收纸中选择最有效的生产方法，以获得具有所需CNF质量的最高产率的CNF，用于各种应用。
