Advanced Functionalized Materials Based on Layer‐by‐Layer Assembled Natural Cellulose Nanofiber for Electrodes: A Review

Abstract

The depletion of fossil fuel resources and its impact on the environment provide a compelling motivation for the development of sustainable energy sources to meet the increasing demand for energy. Accordingly, research and development of energy storage devices have emerged as a critical area of focus. The electrode materials are critical in the electrochemical performance of energy storage devices, such as energy storage capacity and cycle life. Cellulose nanofiber (CNF) represents an important substrate with potentials in the applications of green electrode materials due to their environmental sustainability and excellent compatibility. By utilizing the layer‐by layer (LbL) process, well‐defined nanoscale multilayer structure is prepared on a variety of substrates. In recent years, increasing attention has focused on electrode materials produced from LbL process on CNFs to yield electrodes with exceptional properties, such as high specific surface area, outstanding electrical conductivity, superior electrochemical activity, and exceptional mechanical stability. This review provides a comprehensive overview on the development of functional CNF via the LbL approach as electrode materials.

Advancements in MXene Composite Materials for Wearable Sensors: A Review

“…The progression in nanomaterial technology has heralded the widespread application of materials such as carbon nanotubes (CNTs) [9], silver nanowires (AgNWs) [10], cellulose nanofibers (CNFs) [11], and graphene [12] in the field of flexible electronics, chiefly attributed to their exceptional electrical conductivity and mechanical properties. Among these, two-dimensional (2D) materials have garnered considerable interest due to their distinctive mechanical, optical, thermal, and magnetic electronic characteristics [13].…”
