“…In order to further improve the stability and retention rate of implanted ions, a modification strategy based on ion implantation technology is proposed to precisely control the distribution and concentration of dopant atoms in the polymers. As shown in Figure 7b, under the accelerated fields, polar groups and unsaturated bonds containing N element can not only break the symmetry of the spatial structural of PTFE, but also combine with the free radicals on the chain to form new chemical bonds and chemical groups [105]. The electronegativity and the increase of electron cloud density of the group lead to the improvement of the electron-withdrawing ability.…”

By seamlessly integrating the wearing comfortability of textiles with the biomechanical energy harvesting function of a triboelectric nanogenerator (TENG), an emerging and advanced intelligent textile, i.e., smart textile TENG, is developed with remarkable abilities of autonomous power supply and self-powered sensing, which has great development prospects in the next-generation human-oriented wearable electronics. However, due to inadequate interface contact, insufficient electrification of materials, unavoidable air breakdown effect, output capacitance feature, and special textile structure, there are still several bottlenecks in the road towards the practical application of textile TENGs, including low output, high impedance, low integration, poor working durability, and so on. In this review, on the basis of mastering the existing theory of electricity generation mechanism of TENGs, some prospective strategies for improving the mechanical-to-electrical conversion performance of textile TENGs are systematically summarized and comprehensively discussed, including surface/interface physical treatments, atomic-scale chemical modification, structural optimization design, work environmental control, and integrated energy management. The advantages and disadvantages of each approach in output enhancement are further compared at the end of this review. It is hoped that this review can not only provide useful guidance for the research of textile TENGs to select optimization methods but also accelerate their large-scale practical process.

“…As shown in Figure 7c, through the polyamidation reaction, carbon nanotubes (CNTs) and poly(ethylene terephthalate) (PET) are chemically grafted on the surface of polyester fiber, and a kind of textile TENG with enhanced output is obtained. [ 128 ] In order to solve the issues of low precision and poor stability of traditional surface modification methods, a new scheme based on helium ion irradiation [ 129 ] or nitrogen ion implantation [ 130 ] to inject extra electrons or ions is also developed (Figure 7d). In addition, the external charge excitation strategy through charge pump or shuttle is also an effective method to improve the surface triboelectric charge density (Figure 7e).…”

of textile materials from ancient times to the present, and then to the future is shown in Figure 1, indicating that typical textile materials that can highlight the characteristics of the times have experienced the transformation from natural fiber, artificial/synthetic fiber, reinforced fiber, functional fiber, conductive fiber, and then to smart fiber. Accordingly, the primary purposes or service demands of textile materials have also changed imperceptibly from the aspects of covering, warmth preservation, protection, beauty, security, comfort, health, interaction, and intelligence. On these grounds, it can be found that with the advances of Internetof-Things and artificial intelligences, textile materials are no longer limited to the traditional functions of protection, warm-keeping, and aesthetic, but should be given more smart or intelligent attributes, such as energy harvesting, [1][2][3] energy storage, [4,5] autonomous response, [6,7] information interaction, [8,9] data transmission, [10,11] light emitting, [12,13] color changing, [14] shape memory, [15] thermal regulation, [16,17] selfhealing, [18a] self-adaption, [19] etc. In addition, considering that human oriented wearable electronics will be highly integrated and miniaturized, completely safe and comfortable, and fully portable in the future, it is also expected to design various functional electronics directly into textile structures, such as fibers, yarns or fabrics. [20,21] At present, a variety of functional attributes have been well integrated with textile materials, mainly including energy, [3,4,12,22] sensing, [8,10,23,24] comfort, [16,25a,26,27] and protection, [19,[28][29][30] which endows this kind of traditional necessity of life with new development vitality (Figure 2). In particular, through the seamless combination of electrical functionalities and textile elements, a new type of textiles, namely smart textiles, have been developed, which can perceive, react and adapt to environmental stimuli, including machinery, magnetism, heat, electricity, light, chemistry, biology, and others. [31][32][33][34][35] It can be predicted that the realization of highperformance electrical function and comfortable to wear is the unremitting pursuit goal of the next generation of smart textiles.It is noteworthy that the effective operation of most additional functions in smart textiles depends on sustained and stable energy sources. In other words, we need reliable, compact but high-performance electricity supply systems to power emergingThe seamless integration of emerging triboelectric nanogenerator (TENG) technology with traditional wearable textile materials has given birth to the next-generation smart textiles, i.e., textile TENGs, which will play a vital role in the era of Internet of Things and artificial intelligences. However, low output power and inferior sensing ability have largely limited the development of textile TENGs. Among various approaches to improve the output and sensing performance, such as material modification, structural des...

“…The output of the generator based on this material shows a strong polarization-dependent power output (Figure 7e). Due to the modulated surface potential and negative piezoelectricity of PVDF, the hybrid TP-NG shows Fun et al [152] proposed and discussed the potential mechanism of macroscopic performance regulation from the perspective of chemical molecular structure, and obtained ultra-high negative triboelectric polymers (Figure 7f). However, the key factors that determine the electrical polarity and strength of the polymer have not been fully revealed, and further research is required to facilitate the development of novel triboelectric polymer materials.…”
