The Effect of Nanofibrillated Tempo-oxidized Cotton Linters on the Strength and Optical Properties of Paper

ABSTRACT

This study elaborates the application of composite films based on nanofibrillated cellulose obtained from cotton linters oxidized in the 2,2,6,6-tetramethylpiperidine-1-oxyl radical (TEMPO)/NaBr/NaClO system, with the use of CaCО₃ and/or Al(OH)₃ as fillers, and glycols as plasticizers, to improve the mechanical, optical, and sorption properties of paper. The paper coating with nanofibrillated cellulose-based films, without additional adhesive, depending on the concentration of nanofibrillated cellulose in the dispersion and the type of filler, improves the mechanical properties of paper, and decreases sorption properties, while no significant changes were observed in optical properties compared to the initial papers.

摘要

本研究以2,2,6,6-四甲基哌啶-1-氧自由基 (TEMPO) /NaBr/NaClO体系氧化棉絮, 以碳酸钙和/或氢氧化铝 (OH) 3为填料, 乙二醇为增塑剂, 制备纳米纤维化纤维素复合膜, 以提高其力学性能、光学性能和吸附性能纸张. 用纳米纤维化纤维素基薄膜涂布纸张, 在不添加粘合剂的情况下, 取决于纳米纤维在分散体中的浓度和填充物的类型, 提高了纸张的机械性能, 降低了吸附性能, 但光学性能没有明显变化最初的论文.
