Highly Conductive Ferroelectric Cellulose Composite Papers for Efficient Triboelectric Nanogenerators

Abstract

Paper‐based electronics has attracted growing interest owing to many advantages of papers including low‐cost, abundance, flexibility, biocompatibility, and environmental friendliness. Despite recent progress in paper electronics, however, development of a high‐performance paper‐based triboelectric nanogenerator (TENG), which is a power‐generating device that converts mechanical energy into electric energy by coupling triboelectrification and electrostatic induction, remains a challenge mainly due to weak electron‐donating tendency of cellulose‐based papers. In this work, highly conductive ferroelectric cellulose composite papers containing silver nanowires and BaTiO3 nanoparticles are fabricated, and their successful application for realizing a large‐area TENG with enhanced electrical output performance is demonstrated. It is found that triboelectric charge generation on the ferroelectric cellulose composite paper can be promoted by simple poling treatment, which significantly enhances TENG performance. The ferroelectric cellulose composite paper–based TENG exhibits an electrical output performance that surpasses those of aluminum‐based and pristine cellulose–based TENGs by more than two times, as well as outstanding output stability without a noticeable degradation in performance during 10 000 cycles of a repeated pushing test. The work demonstrates the great potential of multifunctional cellulose‐based papers for TENG and other self‐powered electronic applications.

“…Actually, the more detailed experimental results show that the optimum matching impedance of the TENG with 20% PEG is 160 kΩ (see Figure S7). Briefly, the TENG with 15% PEG content exhibits an enormous enhancement in output power and reduction in impedance compared with previous works, ,,,− which is shown in Table S2. The detailed output characteristics for each TENG are displayed in Figure S8.…”

“…The nano‐graphite layer, with a resistivity of 1.037 mΩ m (Figure S2 , Supporting Information), behaves electrically similar to metallic films that are used in TENGs. [ 10 , 11 , 12 , 13 ] To evaluate its performance, we compared the electrical output of two TENGs: one using a combination of NG@P and PTFE, and the other using copper and PTFE ( Figure 4 a ). The results, shown in Figure 4b,c , revealed that the performances of both TENGs were nearly identical.…”
