| 1 | Understanding the Percolation Effect in Triboelectric Nanogenerator with Conductive Intermediate Layer显示文摘Introducing the conductive intermediate layer into a triboelectric nanogenerator(TENG)has been proved as an efficient way to enhance the surface charge density that is attributed to the enhancement of the dielectric permittivity.However,far too little attention has been paid to the companion percolation,another key element to affect the output.Here,the TENG with MXeneembedded polyvinylidene fluoride(PVDF)composite film is fabricated,and the dependence of the output capability on the MXene loading is investigated experimentally and theoretically.Specifically,the surface charge density mainly depends on the dielectric permittivity at lower MXene loadings,and in contrast,the percolation becomes the degrading factor with the further increase of the conductive loadings.At the balance between the dielectric and percolation properties,the surface charge density of the MXene-modified TENG obtained 350%enhancement compared to that with the pure PVDF.This work shed new light on understanding the dielectric and percolation effect in TENG,which renders a universal strategy for the high-performance triboelectronics. | Binbin Zhang Guo Tian Da Xiong Tao Yang Fengjun Chun Shen Zhong Zhiming Lin Wen Li Weiqing Yang | 2021 | Research2021，，1： | 2 |
| 2 | 氢键键合阳离子组分设计——稳定蓝光PeLEDs发射颜色显示文摘Perovskite light-emitting diodes(PeLEDs)have been considered to be the most promising candidate for solid-state lighting and high-definition full-color display due to their attractive properties such as tunable emission wavelengths,narrow full width at half maximum(FWHM),and high photoluminescence quantum yield(PLQY)[1–3].The external quantum efficiencies(EQEs)of greenand red-emitting Pe LEDs have exceeded 20%,rocketing toward the theoretical limit[4,5],but the blue Pe LEDs still suffer from the obstacles of low efficiency and poor operational stability,which largely overshadows their real applications and industrialscale adoption. | Fengjun Chun Kyung Yeon Jang Tae-Woo Lee | 2021 | Science Bulletin2021，66，21： | 0 |
