“…Additionally, the ability to precise control crystalline phases in polymeric materials is likely to prove beneficial in developing next-generation NGs in the coming years. Recently there have been reports on NGs made from shape memory polymers, which provide recovery from large deformation [100] or even self-healing characteristics to cutting damage on NGs [101]. Although there are a few selfhealing NGs reported based on nanostructured materials [102], most of the attempts remain focused on certain bulk polymers, and there may scope to extend such concepts to polymer-based nanocomposites in order to further increase the energy harvesting performance.…”

Harvesting energy from ambient mechanical sources in our environment has attracted considerable interest due to its potential to power applications such as ubiquitous wireless sensors and Internet of Things devices. In this context, piezoelectric and/or triboelectric materials offer a relatively simple means of directly converting mechanical energy from ubiquitous ambient vibrating sources into electrical power for microscale/nanoscale device applications. In particular, nanoscale energy harvesters, or nanogenerators, are capable of converting low-level ambient vibrations into electrical energy, thus are vital to the realization of the next generation of self-powered devices. Polymer-based nanogenerators are attractive as they are inherently flexible and robust, making them less prone to mechanical failure which is a key requirement for vibrational energy harvesters. They are also lightweight, easy and cheap to fabricate, lead-free and biocompatible, but in many cases their energy harvesting performance is found lacking in comparison to more commonly studied inorganic materials. Recent advances have been made in developing scalable nanofabrication techniques for flexible and low-cost polymer-based nanogenerators with improved energy conversion efficiency, including the incorporation of high-quality polymer nanowires with enhanced crystallinity, piezoelectric and/or surface charge properties. In this review, we discuss aspects of nanomaterials growth and energy harvester device design, including those involving nanowires of polymers of polyvinylidene fluoride and its co-polymers, nylon-11, and poly-lactic acid for scalable piezoelectric and triboelectric nanogenerator applications, as well as the design and performance of polymer-ceramic nanocomposite nanogenerators. In particular, we highlight the effects of growth parameters, nanoconfinement, self-poling, surface polarization, crystalline phases, and device assembly on the energy harvesting performance of a range of recently reported nanostructured polymer-based materials and devices.

“…Nowadays, it is a great interest to focus on energy conversion devices with long lifespan and high efficiencies, such as batteries, solar cells, nanogenerators, and other energy conversion devices ( Figure a–c). Nevertheless, in a practice environment, the stability and power transfer efficiency possibly decrease because these devices are susceptible to the defects and surface damages upon the harsh environment. For example, the occurrence of microcracks and scratches on the surface of solar cells not only reduce the power conversion efficiency but also cause safety concerns .…”

“…For example, the occurrence of microcracks and scratches on the surface of solar cells not only reduce the power conversion efficiency but also cause safety concerns . Besides, as a promising mechanical energy harvester, the triboelectric nanogenerators transfer the mechanical energy into electric energy by the friction between contact surface . and it is self‐evident that the mechanical friction leads to the material surface fracture and ultimately failure.…”

In the past few decades, the self‐healing surface materials with durable mechanical, functional, and structural properties have attracted enormous research interests, which exhibit great potential in energy conversion devices, sensors, electronic skins, superhydrophobic fabrics, medical/biological hydrogel, and a protective coating. Despite the remarkable progresses achieved in the self‐healing surface, the systematic and overall reviews that focus on self‐healing surface materials are still lacking and in urgent need. Herein, the recent advances in the development of self‐healing surface materials are summarized. The surface damage forms that composed of cracks, scratches, punctures, and surface wear, are systematically reviewed. The self‐healing mechanism and methods at interface are then introduced to briefly explain the basic design principle. The recent developments of functional surfaces including superhydrophobic, oleophobic, antifogging, anti‐icing, antibiofouling, and anticorrosion surfaces with self‐healing functions are further discussed. Finally, the contemporary challenges, and the future perspectives that motivate are proposed to create more innovative self‐healing materials for diverse fields.

Energy is the essential requirement of daily life. Due to the diminution of the energy sources, it is necessary develop devices that can harvest the wasted energy that exists in the ambient environment. To address this, triboelectric nanogenerators (TENGs) have been developed as an innovative paradigm for energy harvesting. They can harvest the various forms of mechanical energy, including vibrations, walking, ocean waves, human motion, rain drops, flowing water, the motion of an automobile, wind, rotational energy, and mechanical triggering. TENGs can combine the contact electrification and electrostatic induction for energy conversion and operate on four fundamental modes for conversion of mechanical energy into electrical energy to power small‐scale electronics including mobile phones and sensors. The electrical outputs obtained from TENGs depend on the friction of materials that are selected from the triboelectric series on the basis of their electronegativity and electropositivity. Here, a comprehensive overview of the fundamentals of nanogenerators, various operating modes of TENGs and the design of devices that include them, and the performance improvement of this recently emerged technology is presented.
