我们报告了一种通过化学纯化（去除非纤维素成分）和高速混合机预处理（分解纤维结构）结合高压均化（纳米原纤化），将原始干燥棉纤维原纤化成单个纤维素纳米纤维（CNF）的方法。发现所得的 CNF 具有约 10-30 nm 的宽度和高纵横比。 CNF/丙烯酸树脂复合材料的高透光率表明我们的处理成功地将原棉纤维分解成均匀的CNF。棉CNFs被发现具有高结晶度和热稳定性的优点。
We report a method to fibrillate raw dried cotton fibers into individual cellulose nanofibers (CNFs) by chemical purification (removal of non-cellulosic components) and pretreatment by a high-speed blender (breaking down the fiber structures) combined with high-pressure homogenization (nanofibrillation). The resultant CNFs were found to have a width of approximately 10-30 nm and high aspect ratios. The high light transmittance of the CNF/acrylic resin composite indicated that our treatment successfully disintegrated the raw cotton fibers into uniform CNFs. The cotton CNFs were found to have the advantages of high crystallinity and thermal stability.
