“…Among them, the maximum decomposition temperature of MTPI-4 was the highest, which was 596 C. This is because the mixing of Mo 2 Ti 2 C 3 with PI blocks the motion of the main chain of PI molecules, increases the fracture energy of molecular chain relaxation, and increases the thermal decomposition temperature. 21 At the same time, the unique lamellar structure of Mo 2 Ti 2 C 3 facilitates heat transfer and can avoid localized accumulation of heat. However, when the content of Mo 2 Ti 2 C 3 is too high, its dispersion in the PI matrix becomes poor, leading to poor thermal stability of the composite.…”

Polyimide (PI) has good mechanical properties and thermal stability, while high coefficient (COF) and wear rate limit its wide application. In order to endow PI with better friction and wear resistance, Mo2Ti2C3 MXene was used as solid lubricant to prepare Mo2Ti2C3/PI nanocomposites with different content of Mo2Ti2C3. The effect of the amount of Mo2Ti2C3 on the tribological behavior of PI was explored and the tribological mechanism was also analyzed Tribological tests showed that at 1.2 wt% of Mo2Ti2C3 addition, the composite material demonstrated superior friction and wear resistance, exhibiting a 19.9% decrease in the COF and a 79.7% decrease in the wear rate compared to single PI due to the good self‐lubricating properties of Mo2Ti2C3 MXene. Moreover, Mo2Ti2C3 can also effectively assist PI to form sleek transfer films without interruption or gaps on the steel balls, resulting in a reduced friction COF and wear rate of the material. This work demonstrates that Mo2Ti2C3 MXene is an aussichtsreich additive for polymers to improve the tribological properties and broadens the applications of Mo2Ti2C3/PI composites in friction material area.Highlights Mo2Ti2C3 significantly improves the tribological performance of polyimide. The thermal properties of Mo2Ti2C3/polyimide are enhanced by the introduction of Mo2Ti2C3. The minimum coefficient of Mo2Ti2C3/PI composites was only 0.246 at the 1.2 wt% content of Mo2Ti2C3. The wear rate of Mo2Ti2C3/PI composites was decreased by 79.7% at the 1.2 wt% addition of Mo2Ti2C3. Mo2Ti2C3 promotes the establishment of tribo‐film to protect the Mo2Ti2C3/PI composites from friction.

“…As the TENG need to work for long periods of time, the tribo-material surfaces are frequently subjected to severe wear, which lead to a serious reduction in TENG output performance. Much work has been devoted to improving the wear-resistance of materials, such as material modification [76,[97][98][99][100][101][102][103][104][105], non-contact [106,107], liquid lubrication [108][109][110], etc. Among these, material modification has received the most attention because it is a simple and straightforward approach.…”

“…Among these, material modification has received the most attention because it is a simple and straightforward approach. BaTiO 3 (BTO) nanoparticles [101] and Fe 3 O 4 in synergy with ionic liquid-modified graphene (IGNs) [102] were respectively adopted to enhance the wear-resisting performance of PI. Li et al investigated the effects of BTO nanoparticles doping mass fraction on the triboelectric performance, as shown in figure 10(a).…”

Due to the advantages of excellent output power, low cost and easily preparation, triboelectric nanogenerator is developing rapidly in the field of renewable energy. The output performance of triboelectric nanogenerator is largely dependent on the surface charge density, which is closely related to the ability of the tribo-material to gain or lose electrons. To obtain higher output power, numerous efforts have been done on material modifications of the friction layer and electrodes of triboelectric nanogenerator with additional fillers or molecular modifications. In this review, advanced materials for the preparation of triboelectric nanogenerator devices to achieve high output, humidity-resisting and wear-resisting performance are presented and the working mechanisms of performance optimisation are discussed. Moreover, natural materials, recyclable materials and non-conventional electrode materials are mentioned to inspire subsequent research on triboelectric nanogenerator.

“…Typically, most materials will sacrifice their mechanical and electrical properties under extreme high or low temperatures, especially hydrogel materials. [100,101] Accordingly, the triboelectric charge of materials usually will be dissipated due to thermionic emission, causing degradation of output. Strategies such as using ionic gel, organic hydrogel, and phase change materials to maintain TENG performance under extreme high and low temperatures are desired.…”

As a distributed environmental energy harvesting device, triboelectric nanogenerators (TENGs) inevitably encounter different and extreme application scenarios, such as environment with high temperature, high humidity, corrosion condition, frequent mechanical stimulus, and physical damages, which resulting in triboelectric performance degradation either by damaging device structure or reducing surface potential, and accelerating dissipation of surface bound charge. Therefore, tremendous efforts are dedicated to improving the TENG performance, enabling devices are competent in sustaining various challenging conditions. This review summarizes and highlights the latest research progress of strategy to achieve TENGs with high environmental adaptivity in three representative application fields of interfacial devices, wearable devices and implantable devices, aiming to gain insights in terms of material selection, structural design, preparation technology, working mode and integration strategy. The future development of the TENG would transform from static to dynamic device that possesses multifunction, high stability, autonomous response and actuation ability to adapt complex application environment. It is hoped that this review article could steer the development of environment‐adaptive TENGs to a higher level.
