Micro/Nanocellulose Functional Membranes for Energy and Environment

In the next few decades， one of the biggest challenges we face is to find green， clean resources and materials to maintain high efficient social economy growth. The development of sustainable resources and materials is the most promising solution to reduce the proportion of traditional fossil energy and materials. Cellulose is a sustainable， renewable， abundant， cost-effective natural polymer， which has extensive applications in many fields， and can be processing into various configurations， including aerogel， foam， sponge， film and so on. This review introduces the application of the functional membranes that assembled from different forms of cellulose and its derivatives in energy and environment. There are reviews for the latest progress and preparation schemes of micro/nanocellulose and its derivatives in advanced high-performance functional energy storage devices， as well as their applications in membrane separation technologies for water treatment. Then， it focuses on the roles of micro/nanocellulose and its derivative functional membranes in batteries， capacitors， water treatment， etc.， such as separator， flexible electrode membranes， separation membranes and so on. Furthermore， the functional films of cellulose and its derivatives are summarized and prospected.
