| Abstract: |
| Triboelectric Nanogenerators (TENGs) have emerged as a promising technology in the field of renewable energy due to their ability to convert mechanical energy into electrical power through the triboelectric effect. Despite the significant advances in the TENG technology, the durability of these devices remains a major challenge, as friction-induced wear and mechanical degradation can significantly diminish their performance over time. To address this issue, it is crucial to enhance the wear resistance and overall longevity of TENGs, so as to ensure their practicality in long-term applications. This review focuses on the potential of Diamond-ike Carbon (DLC) films to improve the wear resistance, energy conversion efficiency, and durability of TENGs. DLC films are renowned for their exceptional hardness, low friction, chemical stability, and favorable electronic properties, making them ideal candidates for enhancing the operational lifespan of TENG devices. The application of DLC films in TENGs has been shown to reduce friction and wear, which are critical factors in prolonging the service life of devices. The low surface energy of DLC films not only minimizes mechanical degradation but also increases the efficiency of energy conversion by improving the triboelectric effect. These properties make DLC coatings a key solution to enhance the stability and consistency of power output from TENGs. Furthermore, DLC films can be tailored to optimize the mechanical and electrical properties of TENGs, which is crucial for applications that demand high performance and long-term reliability. Key areas of application include self-powered sensors, wearable electronics, environmental energy harvesting, microelectronic devices, and the Internet of Things (IoT), all of which benefit from the extended durability provided by DLC coatings. In addition to their wear resistance, DLC films also offer avenues for performance optimization through various modification techniques. Strategies such as surface functionalization, multi-layer structural designs, doping modifications, and composite material engineering have been explored to enhance the overall performance of DLC-based TENGs. Surface modifications, such as incorporating nanomaterials or introducing self-healing properties, can further reduce wear and improve mechanical stability of DLC films. Additionally, multi-layer design that combines DLC with other materials help balance durability and energy conversion efficiency. The development of low-cost, high-performance DLC composites is a key area of ongoing research, offering the potential for cost-effective and scalable solutions in production of durable and efficient TENGs. By discussing, this review concludes the future directions for the DLC-TENG technology, including the need for further material innovations, structural optimizations, and the integration of TENGs into smart, self-powered systems for a sustainable energy future. |
