Multifunctional cellulose paper-based materials.

Owing to their intrinsic properties of wide availability, low cost, portability, environmental friendliness and degradability, paper and paper-based materials are receiving increasing attention since birth. Recent increasing studies suggest that paper and paper-based materials possess bright application prospects for the purpose of realizing sustainable development and green circular economy soon. Under this background, more and more correlated application fields for paper and paper-based materials, such as advanced paper-based packaging, writing paper (paper-based transistors), environmental protection (oil/water separation), interface sensing (paper-based sensor devices and microfluidic platforms), energy conversion/storage devices (paper-based triboelectric nanogeneration, paper-based bio-batteries and supercapacitors) have been emerged. In addition, the challenges faced in utilizing the current paper-based materials are analyzed, including fundamental problems, practical applications, and development prospects. The current review not only provides theoretical guidance for the construction of functional paper-based materials, but also helps to expand their application scope and extend their lifespan. It is expected that this review will inspire future research regarding the novel practical applications of paper-based materials. [ABSTRACT FROM AUTHOR]
