Agricultural waste corn stover has little economic value. Cellulose was extracted from corn stover by the processes of alkali treatment and delignification, resulting in a >93% purity. The particle size of the extracted cellulose was reduced by mechanical shearing through high pressure homogenization. When passing through a homogenizer thirty times, the cellulose nanofibril (CNF) can be obtained. The diameters of the CNF ranged between 5 and 50 nm, and the lengths were microns. The mechanical properties of the films, made by corn stover cellulose, with and without high pressure homogenization shearing were evaluated using an Instron instrument. The films made by cellulose without shearing exhibited weaker mechanical properties, while the CNF films exhibited stronger mechanical properties. The linear rheological properties of CNF suspensions were also investigated and results show solid-like viscoelastic behavior. Our findings regarding corn stover CNF are similar to those CNF from other sources reported in the literature.

农业废玉米秸秆的经济价值很小。通过碱处理和脱木质素工艺从玉米秸秆中提取纤维素，纯度> 93％。通过高压均质化通过机械剪切减小提取的纤维素的粒度。当通过均质器三十次时，可以获得纤维素纳米原纤维（CNF）。CNF的直径在5至50nm之间，并且长度为微米。使用Instron仪器评估在有和没有高压均质剪切作用下由玉米秸秆纤维素制成的膜的机械性能。由纤维素制成的没有剪切的膜表现出较弱的机械性能，而CNF膜表现出较强的机械性能。还研究了CNF悬浮液的线性流变特性，结果显示出类似固体的粘弹性行为。我们关于玉米秸秆CNF的发现与文献中报道的其他来源的CNF相似。
