“…However, the coating of polymer foams with metal films via electroless deposition has been limited to the preparation of stretchable interconnections and electrodes with applications in flexible and wearable electronics. [15][16][17] On the other hand, the coating of the inner surface of polymer foams with nanoscopic fillers has been leveraged to modify the physio-chemical, [19][20][21][22][23][24][25] mechanoelectrical, 17,[26][27][28][29][30][31][32] and topological [26][27][28] properties of the foams and gain, in turn, novel features. Applications of such nanocomposites include sensing structures, [26][27][28][29][30][31][32][33][34] stretchable electronics, 17,20,35 environmental cleaning, 19,21,[36][37][38] and biomedical devices.…”

“…Ex situ approaches are based on preformation of the nanofillers, i.e. NPs, nanowires (NWs), nanotubes (NTs), and nanosheets (NSs), which are then integrated on the surface of the porous hosting material by dropcasting 26,27,31 or dip coating 8,21,22,24,25,29,32,[42][43][44] methods. These approaches permit fine-tuning of the size and morphology of the nanofillers through wet and vapor phase processes, though they suffer from sophisticated and costly preparation of the nanofillers, limited adhesion of the nanofillers to the polymer surfaces, severe aggregation at high concentrations, and uneven coating of the inner surfaces of the pore network.…”

“…Therefore, in a triboelectricity storage system, a higher external surface area led to enhanced surface charge density, which was due to the presence of a larger contact area with a smaller particle size (Note S1, Supporting Information). [56,57] The surface charge density and energy storage of TENG are detailed in the Supporting Information (Figure S8 and Note S2, Supporting Information).…”

As a method to maximize the energy efficiency of triboelectric nanogenerators (TENGs), high‐voltage charge injection (HVCI) on the surface is a simple and effective method for increasing surface charge densities. In this study, positive and negative triboelectric series are controlled using a 3‐layer gradient charge‐confinement wherein the particle sizes of the mesoporous carbon spheres (mCSs) are sequentially arranged depending on the external surface area of the mCSs. In the gradient charge‐confinement layers of this study, the mCS with different sizes perform charge transport from the surface to a deep position during HVCI while mitigating the charge loss through charge confinement to induce the high space charge densities. Through this process, the output voltage—which is initially 15.2 V—is measured to be 600 V after HVCI, thus representing an increase of about 40 times. Further, to amplify the low output current, which is a disadvantage of triboelectric energy, two types of electrical energy—triboelectric and electromagnetic energy—are produced in single mechanical motion. As a result, the output current produced by the cylindrical TENG and electromagnetic generator is recorded as being 1300 times higher, increasing from 12.8 µA to 17.5 mA.

“…There is a plausible consequence that the semiconductor materials and the 2D nanomaterials can generate carriers through light irradiation. [ 22 , 23 , 24 , 25 , 26 , 27 ] Some researchers have adopted the semiconductor materials such as TiO 2 as the triboelectric layer. These studies verify that the light can regulate the output electricity of TENG as the materials are sensitive to the light, but photon‐generated carriers are not involved in the process of regulating output electricity of the TENG, and the TENG utilized these materials possess low power.…”

Boosting the output performance of triboelectric nanogenerators via some unique methods is always a meaningful way to speed up their commercialization. However, the available approach to boost performance is mainly restricted to one physics effect based and the basic research of boosting performance via mutual coupling effects is little research. Herein, a new strategy is creatively proposed based on charge traps from mutual coupling effects, generated from g-C 3 N 4 /MXene-Au composites, to further promote the output performance of triboelectric nanogenerator. It is found that photon-generated carriers coupling surface plasmon effect enables composites filled into tribo-material with visible light is an excellent value in boosting performance. The charge traps from mutual coupling effects for boosting performance are analyzed theoretically and verified by experiments. The output power of boosting-triboelectric nanogenerator (TENG) achieves a sixfold enhancement (20 mW) of normal TENG with polydimethylsiloxane (PDMS) in ambient conditions. This work provides a profound understanding of the working mechanism of mutual coupling effects boosting the performance of TENG and an effective way for promoting TENG output.
