A comprehensive research was conducted to compare mechanical, optical, and water absorption properties of chitosan/chitin nanofiber (ChNF) nanocomposites, prepared by acetic acid in form of uncross-linked biofilms and adipic acid in form of physically (uncured) and chemically (cured) cross-linked biofilms. The chemical and morphological characterizations revealed that the isolated ChNFs contained almost 88% chitin, with crystallinity and average diameter of 84% and 21 nm. Mechanical properties of uncross-linked chitosan biofilms increased with loading ChNFs up to 5 wt% (wt.%), albeit their elongations at break declined—this reduction was then compensated using plasticizer. Moreover, it was found that the cured biofilms containing 5 wt% ChNFs and 20 wt% glycerol showed the highest strength. The superior resistance to water absorption was also observed in case of the cured biofilms, and transparency test showed that adding ChNFs and glycerol could reduce the transparency of chitosan biofilms.

进行了一项综合研究，以比较壳聚糖/几丁质纳米纤维（ChNF）纳米复合材料的机械，光学和吸水性能，该复合材料是由未交联生物膜形式的乙酸和物理（未固化）和化学（固化）形式的己二酸制备的）交联的生物膜。化学和形态学特征表明，分离出的ChNFs含有近88％的几丁质，结晶度和平均直径分别为84％和21 nm。未加交联的壳聚糖生物膜的机械性能随ChNFs含量增加至5 wt％（wt。％）而增加，尽管其断裂伸长率降低了，然后用增塑剂补偿了这种降低。此外，发现包含5wt％的ChNF和20wt％的甘油的固化的生物膜显示出最高的强度。
