“…Therefore, to address this issue, conductive materials like PPy are generally combined with a polymer matrix to prepare composites that achieve both high electrical conductivity and good mechanical properties. Until now, several flexible polymers including polyurethane, silk, collagen, cellulose, and so forth have been studied and used as a matrix to prepare conductive composite materials. In particular, the cellulose mainly derived from cotton and lignocellulosic biomass is the most abundant renewable biopolymer on earth .…”

“…Cellulose is therefore widely used as a positive friction layer. To date, many kinds of cellulose-including hydroxyethyl cellulose, 50 cellulose acetate (CA), 51 bacterial cellulose (BC), 52 and natural wood-derived lignocellulosic 53 nanobrils-have been explored for use in various TENGs. 54 In addition, diverse modication strategies-e.g., material modications and surface-structure optimization-have been utilized to improve the output performance of cellulose-based TENGs.…”

“…To enhance the output performance of TENGs, materials possessing large differences in triboelectric charge density and with surface modifications are typically chosen in order to increase the triboelectric charge generation. , The triboelectric charges generated on the surface of a friction material exhibit a clear charge decay phenomenon in which they combine with the interfacial charges on the electrode. , Therefore, the triboelectric charge generation and charge retention of TENGs need to be taken into account in order to improve output performance. In recent reports, it is shown that introducing a charge transition-blocking interlayer between the friction material and electrode could prevent triboelectric charge decay and boost the performance of TENGs. , The interlayer thickness, morphology, and polarity have significant effects on the charge transitions, blocking ability, and finally on the output performance of TENGs. , A charge transition-blocking layer that is thicker than the triboelectric layer with a lower charge carrier mobility is essential for effectively blocking the charge decay and thereby better charge retention. , Polymers containing charge traps that are formed by imperfections in the crystal lattice or cross-linking points, as well as dangling bonds and functional groups, can prevent charge recombination across the interface. , Feng et al designed a PVDF-nylon-based TENG by introducing a 25 μm-thick polyimide charge storage layer between the PVDF and electrode.…”
