Single-factor and orthogonal tests from Preparation of nanocellulose from bagasse and its application in chitosan composite films

The effects of different CNC, CS and glycerol additions on the properties of composite films, including film thickness, tensile strength and elongation at break, were determined.Based on the results of the single-factor experiments, the CNC/CS composite film with a closer thickness and better mechanical properties was selected to design an L9 (34) orthogonal test, and the results are shown in the file 1.本研究测定了不同添加量的纤维素纳米晶体（CNC）、壳聚糖（CS）与甘油对复合薄膜各项性能的影响，测定指标涵盖薄膜厚度、拉伸强度及断裂伸长率。基于单因素试验结果，筛选出厚度更为均匀且力学性能更优的CNC/CS复合薄膜，以此设计L9(3⁴)正交试验，试验结果详见文件1。
