The dissolution of cellulose endows the green and environmentally friendly cellulosic material with a wide range of processing properties, further enhancing its advantages as a basic material. However, its unsatisfactory mechanical performance and functionality severely limited its practical application. Herein, a facile molecular orientation strategy was developed to orient the aggregated structure of the dissolved cellulose in the lithium chloride/N,N-dimethylacetamide system and to obtain high-performance films. During the preparation process, cross-linking, stretching, and hot pressing wer...
