Triboelectric nanogenerators (TENGs) were first developed in 2012, and have become the desirable choice as energy harvesters in the research community worldwide. The popularity of TENGs is attributed to their low weight, low cost, high output, wide range of materials and device designs. TENGs have been explored for many applications including sensing, implantable power sources, healthcare, and biomedical applications. The performance of TENGs depends largely on the material since charge density (σ) is a material property. Moreover, 2D materials have been investigated as an alternative to the conventional metal electrodes. The dominance of polymers and metals in the traditional triboelectric series has lead researchers to explore novel materials to extend the applications and improve TENG output. This review article summarizes the progress in the development of frictional layers and electrode materials for TENGs. The mechanism for the output enhancement and device applications are discussed in detail. Finally, a perspective on the future and relevant challenges in material development for TENGs are discussed.

Covalent organic frameworks( COFs) enablep recise integration of variouso rganic building blocks into porouss keletons through topology predesign. Here,w e report the first example of COFs by integrating electron withdrawing bromine group onto the skeletons for triboelectricn anogenerators (TENG). The resulting framework exhibits high surface area and good crystallinity.T hus, the brominef unctionalizedC OF has more regular aligned p columns and arrays over the skeleton than bare COFs, which in turn significantly enhances chargetransport ability.A saresult, bromine functionalized COFs showed higher electrical outputp erformance at 5Hzw ith ap eak value of short circuit current density of 43.6 mAa nd outputv oltage of 416 V, which is 2a nd 1.3 times higher than those of bareC OFs (21.6 mAa nd 318 V),r espectively. These results demonstrated that this strategy for engineeringelectron withdrawingg roupso nt he skeleton could open an ew aspect of COFs for developing TENG devices.Triboelectricn anogenerators (TENG) are an ovel device that can effectively convert ambient mechanical energy,s uch as body motion, wind and vibratione nergy into electrical energy.

“…Therefore, many researchers have been developing various types of TENG [23][24][25][26][27][28][29][30]. The contact area between two triboelectric layers plays a major effect on TENG's properties [31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47]. There have been previous works focused on materials selection [48][49][50][51][52][53][54], surface modification [41,[55][56][57][58][59][60][61][62][63], and control of surface topography [64][65][66] to investigate the triboelectrification mechanism on the performance of triboelectric nanogenerators.…”

Triboelectric nanogenerator (TENG) is the new technique that can convert low-frequency mechanical energy into effective electricity. As an energy collector, the pursuit of high output characteristics is understandable. Although high charge density has been achieved by working in high vacuum or charge pumping techniques, it remains challenging to obtain the high output performance directly in the atmosphere. Herein, surface-engineering of the triboelectric layer for enhancing output performance has been reviewed carefully. By constructing surface morphology or developing surface modification, high performance of TENGs is finally presented in the review.
