“…6,13 Pairing materials with opposite tribo-polarities, and increasing surface roughness to facilitate contact, are effective strategies to improve the electrical performance of TENGs. [14][15][16] In recently proposed examples of wood-based TENGs, the triboelectric output was generated by simply coupling native wood with highly polarizable materials (such as PTFE). In such approaches, however, wood itself does not play a role in improving the output performance of TENG.…”

We describe a functional wood triboelectric nanogenerator (FW-TENG) made by modifying a wood scaffold respectively with ZIF-8 and PDMS. Our approach enables wood with a wide spectrum of triboelectric polarities while preserving its sustainability and aesthetic appearance. We demonstrate the application of our FW-TENG as an energy-harvesting wooden floor or panel, allowing it to power household lamps and other electronic devices when activated by walking or tapping.

Ocean contain abundant clean energies including tidal and wave, but such energies are known for low frequency and large excitation amplitude, posing considerable challenges for high‐efficiency energy conversion. As an emerging technology, triboelectric nanogenerators (TENGs) have been widely used in energy harvesting and novel sensor design due to their high sensitivity and flexible structure. Meanwhile, they show great advantages in the low‐frequency environment (<5 Hz), and display great potential for deployment in remote ocean waters, and construction of large‐scale TENG networks. In this review, firstly, the working principle of TENGs and various configurations developed for the marine environment are introduced, which mainly include solid–solid and solid–liquid interfaces. Then, from the viewpoint of power improvement, authors are most concerned about the modification methods of materials such as surface modification, electron injection, and chemical doping. Meanwhile, improved technologies for energy harvesters in marine environment are discussed in detail, such as improving the hydrophobicity and degradation of materials, studying the self‐healing ability of materials, and designing power management circuits. Finally, the current challenges are summarized, and research trends are given from both short‐term and long‐term perspectives.

“…Based on the previous reports, several key factors affecting the output performance of TENG such as frictional contact surface and surface charge density of the F I G U R E 2 Effect of ChL/MeOH volume ratio on the surface morphology of the hc-GO-S/PLA film two electrode layers were indicated. 8,[15][16][17]30 Our recent work has focused on the formation of A-TENG with the assistance of GO-S as well as comparison among flat TENG, honeycomb TENGs with and without GO-S to fully understand the effects of surface-patterning combined with GO modification on electrical property of TENG. Figure 4 includes the electrical performance of A-TENG, which was evaluated in this research.…”

“…To ameliorate the output performance of TENGs, the surface contact area, surface charge density, and dielectric constant are the most important and notable factors due to their impacts on contact-separation power production and triboelectrification properties of TENGs. [15][16][17] It is necessary to note that chosen tribomaterials mainly determine the surface properties of TENGs based on opposite ends of the triboelectric series. Therefore, many groups of scientists experimented with various concepts to improve TENGs such as using electron-donating additives (diatom) to supplemental charge biopolymer chitosan resulting in a 3.7-time increase in power density, 16 surface patterning of polydimethylsiloxane (PDMS) paired with flat aluminum producing a relatively high power density of 8.1 W m À2,18 forming the porous structure of the materials to harvest a maximum output voltage of 345 V and short circuit current of 3 μA cm À2 , resulting in 330% enhancement in the power output, 19 using sandpaper to roughen tribo-surfaces which is simple but uncontrollable.…”

Porous graphene oxide-surfactant/poly(lactic acid) (GO-S/PLA) nanocomposite film with highly ordered hexagonal pore arrangement was fabricated via a combination of ionic interaction-supported GO dispersion and the improved phase separation method. First, a flat nanocomposite film is prepared by coating a welldispersed GO-S/PLA solution on a solid substrate. Subsequently, the film is exposed to a mixture of chloroform and methanol as a suitable volatile solvent/ nonsolvent pair for both PLA and surfactant-grafted GO sheets. A monolayer of honeycomb patterns is spontaneously formed on the nanocomposite surface after complete evaporation of liquids under normal air conditions. Methanol plays a crucial role in effectively inducing and controlling the ordered honeycomb structures. The pore array features, which include pore diameter and pore density, are tuned by adjusting methanol content. Moreover, the patterned GO-S/PLA nanocomposite demonstrates as an efficient electrification component for highperformance triboelectric nanogenerator (TENG) owing to a large surface area and abundant electron-donating groups of GO sheets. A new TENG is composed of the honeycomb GO-S/PLA (hc-GO-S/PLA) and its replica of microdomepatterned polydimethylsiloxane (md-PDMS), as a pair of tribo-components with antagonistic friction surfaces. As a result, it can generate an output power of 0.54 mW cm À2 which is 8.6 times higher than that of TENG with a flat surface and without GO additives. We believe that hc-GO-S/PLA nanocomposite has potential applications in biotechnology, optics, and catalyst fields.
