Fe3O4-Filled Cellulose Paper for Triboelectric Nanogenerator Application

Abstract

Cellulose-based materials have recently drawn much interest due to their sustainability, biodegradability, biocompatibility, and low cost. In this present work, cellulose fiber paper (CFP) was fabricated from sugarcane leaves and used as a friction material for a triboelectric nanogenerator (TENG). Fe3O4 was incorporated to CFP triboelectric material to increase the dielectric constant of CFP for boosting power generation of TENG. The Fe3O4 filled CFP was synthesized using a facile one-pot co-precipitation technique. The effect of Fe3O4 content in CFP on dielectric property and TENG performance was investigated and optimized. The CFP filled with Fe3O4 nanoparticles exhibited the improved dielectric constant and possessed a superior TENG performance than pristine CF. The highest power density of 1.9 W/m2 was achieved, which was able to charge commercial capacitors serving as a power source for small electronic devices.

Using Natural Dye Additives to Enhance the Energy Conversion Performance of a Cellulose Paper-Based Triboelectric Nanogenerator

“…Cellulose fibers were extracted from sugarcane leaves, as described in our previous work [ 9 ]. Briefly, sugarcane leaves were firstly washed and dried in an oven at 60 °C for 48 h. The dried sugarcane leaves were then cut and ground with a grinder machine to obtain powders with an approximate size of 200 µm.…”

“…Besides the key advantages given above, cellulose papers have diversity for modification, a light weight, and good mechanical properties, rendering them an ideal material for fabricating a TENG. In recent years, great efforts have been made to explore cellulose-based TENGs for energy harvesting and sensing applications [ 4 , 5 , 6 , 7 , 8 , 9 , 10 ]. Cellulose paper has been recently reported for its highest record power density of over 300 W/m 2 [ 11 ].…”

“…Since the electrical output of a TENG is governed by the triboelectric charge density [ 12 ], a number of approaches have been reported for boosting the power output of cellulose paper-based TENGs [ 13 ]. These include physical and chemical modifications [ 14 ], for example, constructing a hierarchical nanostructure to increase the surface area [ 15 ] and dielectric modulation with the addition of BaTiO 3 [ 16 ], Fe 3 O 4 [ 9 ], dielectric materials, and chemical functionalization [ 17 , 18 ]. Aside from the aforementioned approaches, triboelectric charge density is also enhanced through photogenerated charges under the illumination of light.…”

Morphology and structure of sawdust waste after adding magnetic nanoparticles

“…Moreover, the incorporation of mechanical interlocking serves to further restrict the cellulose fibrils movement by magnetic nanoparticles, consequently bolstering the strength of the resulting nanocomposite [15,16]. Notably, Magnetic nanoparticle systems have demonstrated their ability to efficiently inhibit communities of fecal coliform and enterococci bacteria [17], as well as enhancing the charge capacitance capacity of cellulose material [18]. Efforts are being made to functionalize magnetic nanoparticles from sawdust when applied as a wastewater flocculant or coagulant for easier separation using a magnet.…”

“…They have several virtues, such as being compact, affordable, stable, etc. They are also most suitable for use in self-powered devices [ 6 , 18 , 22 , 23 , 24 , 25 , 26 , 27 ]. Electrostatic induction and contact electrification are the operating mechanisms of the nanogenerator [ 28 ].…”
