Waste Plastic Triboelectric Nanogenerators Using Recycled Plastic Bags for Power Generation

Abstract

Tens of thousands of plastics produced by people have caused incalculable harm to the environment. At the same time, the consumption of energy is becoming more and more serious, and the use of fossil energy to generate electricity has caused further damage to the environment. It is a good way to recycle waste plastics and make energy collection and generation devices based on them. Here, a triboelectric nanogenerator (TENG) based entirely on waste plastic bags is proposed. Three types of TENGs, PA-PVC-TENG, PA-PE-TENG, and PVC-PE-TENG, were fabricated by selecting the most common PA, PVC, and PE plastic films as the triboelectric layer. The output performance was improved by gilding the back of the plastic films as a conductive electrode. Under different conditions, three different types of TENGs were tested. The PA-PVC-TENG was found to show the best output performance with an open-circuit voltage of 35.7 V, a short-circuit current of 5.85 μA, and a maximum output power density of 152.6 mW/m2. After further integration with supercapacitors, the integrated system can drive multiple commercial LEDs, and it can be used as an antitheft device to achieve early warning. This study realizes the integration of a TENG and energy storage devices, and as a TENG is based entirely on waste plastic bags, it not only realizes the recycling of plastics but also further realizes power generation, which can alleviate energy consumption to some extent.

High Cycle Stability of Hybridized Co(OH)2 Nanomaterial Structures Synthesized by the Water Bath Method as Anodes for Lithium-Ion Batteries

“…To solve the problems of growing exhaustion of fossil energy (petroleum, natural gas, and coal) and the resulting environmental issues, many energy conversion and storage systems, such as lithium-ion batteries (LIBs), nanogenerators, and supercapacitors, have been extensively investigated [1][2][3][4][5][6][7][8][9][10][11][12][13]. LIBs have attracted much attention owing to their low self-discharge, no memory effect, high working voltage, and high energy density [14][15][16][17][18][19].…”

Accelerated Iterative Learning Control for Linear Discrete Time Invariant Switched Systems

“…Due to the above characteristics, the learning algorithm has been favored by many scholars in recent years, which makes it widely used in the control of a robot rigid manipulator [12,20], batch processing in industries [21], aerodynamic system [22], traffic control system [23], electrical power system, etc. [24][25][26]. However, at present, most scholars have only performed a lot of research on the control of nonswitched systems, while there are few research results on the iterative learning control of switched systems [27].…”

Novel Recycled Triboelectric Nanogenerator Based on Polymer‐Coated Trash Soda Can for Clean Energy Harvesting

“…[14][15][16][17] Similarly, Wang et al used the different waste plastic bags to develop recycled triboelectric nanogenerator. [18] However, different techniques are generally required to deposit the tribopositive film on the metal electrode. [19,20] Soda can polymer coating by simply function-change as a tribopositive film does not require any further processing for TENG device will not only decreases the fabrication cost but also is useful for a clean environment.…”
