Here, transparent films were prepared from regenerated cellulose. Microcrystalline cellulose was solubilized in N,N-dimethylacetamide with lithium chloride. Exchange of organic solvent for water resulted in the gelation of solution. Transparent hydrogel served then for stable film preparation. No cellulose chemical modification and cross-linking was applied. To reinforce films, 5 wt% montmorillonite was added. Both pristine and modified clay was used. Modification was provided through intercalation by synthesized polyhedral oligomeric silsesquioxane (POSS) bearing eight amino groups. Examination of films with modified montmorillonite revealed its exfoliation for clay nanoparticles and POSS in the course of their preparation. In that case, a significant increase of tensile strength and elongation at break was observed, while a notable decrease of transparency for the UV part of the sun spectrum was also observed, which is important for the UV protection by cellulosic materials.

在此，由再生纤维素制备透明膜。用氯化锂将微晶纤维素溶解在N，N-二甲基乙酰胺中。用有机溶剂交换水导致溶液胶凝。然后将透明水凝胶用于稳定的膜制备。没有应用纤维素化学改性和交联。为了增强膜，添加了5重量％的蒙脱石。原始粘土和改性粘土均被使用。通过带有八个氨基的合成多面体低聚倍半硅氧烷（POSS）的插层提供修饰。用改性的蒙脱石对薄膜进行的检查表明，在制备过程中，其对粘土纳米颗粒和POSS的剥离作用。在这种情况下，观察到拉伸强度和断裂伸长率显着增加，
