Graphene modified cellulose membrane and preparation method thereof

The invention provides a graphene modified cellulose membrane and a preparation method thereof. The preparation method of the graphene modified cellulose membrane comprises the following steps of firstly dissolving graphene materials into ionic liquid; then, adding swelling cellulose; performing dissolution and uniform forming; then, performing membrane casting, water washing, plasticization and drying to obtain the cellulose membrane. The problem of cellulose membrane intensity reduction after the introduction of functional additives is solved. 本发明提供了种石墨烯改性纤维素膜及其制备方法，其制备方法为：先将石墨烯材料溶于离子液体中，再向其中加入溶胀后的纤维素，使其溶解、混匀，之后经过铸膜、水洗、增塑和干燥，得到纤维素膜。本发明解决了引入功能添加剂后纤维素膜强度降低的问题。
