| 3 | Manipulating functional groups between polyvinylidene difluoride and nanoparticles for high-performance triboelectric nanogenerator显示文摘Interface functional groups play an essential role in regulating the electrical properties of bulk materials.In this work,we designed a novel strategy to explore a new way to enhance triboelectric performance by regulating the functional groups between nano-fillers and polymer matrix without obvious changes in the dielectric constant.The silica nanoparticles(SNPs)modified perfluoro-silane coupling agents(PFSCAs)with different chain lengths were added to the polyvinylidene difluoride to regulate the transferred charge density(TCD)of triboelectric nanogenerators(TENGs).When the doping concentration of perfluorodecyl modified SNPs is 2.25 wt.%,the nanocomposite film based TENG exhibits the maximum TCD of 166μC/m^(2)and power density of 3.12 W/m^(2)which are 6 times and 39 times as big as those of pure polyvinylidene difluoride(PVDF)film.The charge accumulation and decay process show that interface functional groups dominate the performance of TENGs.Then,a Fermi level model is proposed and why the TCD could be regulated by the concentration of nanoparticles in bulk materials is explained.This work provides a new concept for understanding the performance of TENG independent dielectric constant and points out a new direction for enhancing TENG’s performance,since wealthy functional groups with selectivity are applicable. | Zekun Li Lu Zhang Lihao Guo Wenwen Hu Aifang Yu Junyi Zhai | 2023 | Nano Research2023，16，9： | 1 |
| 4 | Lighted up by hydrogen-bonding: luminescence behavior and applications of AIEgen-doped interpenetrating network hydrogel显示文摘The interaction between the aggregation-induced emissive(AIE) luminogens(AIEgen) and the polymer is the key scientific question in the design of functional AIE hydrogels. In this study, we report the AIE behavior of a poly(acrylic acid)(PAAc) and poly(acrylamide)(PAAm) interpenetrating network(IPN) hydrogel doped with tetra-cationic tetraphenylethene(TCTPE). The cationic AIEgen can bind with PAAc through ionic interaction, while PAAc and PAAm chains can associate with each other through hydrogen-bonds(H-bonds). These two interactions can restrict the intramolecular rotation and thus activate the luminescence of the AIEgen. The PAAc-PAAm H-bonds can be broken by increasing temperature or p H, restoring the intramolecular rotation of the AIEgen and quenching the fluorescence of the hydrogel. Therefore, the TCTPE-doped IPN hydrogel is designed as temperature-and p H-sensitive displayers which can record information imprinted by photo-printing or iono-printing with good switchability and reversibility. Another application of this TCTPE-doped hydrogel is demonstrated as a luminescent soft actuator, which has fast shape deformation and editable fluorescence pattern. The above results reveal a pathway to tune the emission behavior through tuning polymer-polymer and polymer-AIEgen interactions, which may inspire new design strategies of aggregation-induced emissive polymers and broaden their applications. | Mengdi Xu Luqin Hua Lihao Gong Jianlei Lu Jinhui Wang Chuanzhuang Zhao | 2021 | Science China Chemistry2021，64，10： | 1 |
| 5 | Investigation on step overcharge to self-heating behavior and mechanism analysis of lithium ion batteries显示文摘To obtain intrinsic overcharge boundary and investigate overcharge mechanism,here we propose an innovative method,the step overcharge test,to reduce the thermal crossover and distinguish the overcharge thermal behavior,including 5%state of charge(SOC)with small current overcharge and resting until the temperature equilibrium under adiabatic conditions.The intrinsic thermal response and the self-excitation behaviour are analysed through temperature and voltage changes during the step overcharge period.Experimental results show that the deintercalated state of the cathode is highly correlated to self-heating parasitic reactions.Before reaching the upper limit of Negative/Positive(N/P)ratio,the temperature changes little,the heat generation is significantly induced by the reversible heat(endothermic)and ohmic heat,which could balance each other.Following that the lithium metal is gradually deposited on the surface of the anode and reacts with electrolyte upon overcharge,inducing selfheating side reaction.However,this spontaneous thermal reaction could be“self-extinguished”.When the lithium in cathode is completely deintercalated,the boundary point of overcharge is about 4.7 V(~148%SOC,>40℃),and from this point,the self-heating behaviour could be continuously triggered until thermal runaway(TR)without additional overcharge.The whole static and spontaneous process lasts for 115 h and the side reaction heat is beyond 320,000 J.The continuous self-excitation behavior inside the battery is attributed to the interaction between the highly oxidized cathode and the solvent,which leads to the dissolution of metal ions.The dissolved metal ions destroy the SEI(solid electrolyte interphase)film on the surface of the deposited Li of anode,which induces the thermal reaction between lithium metal and the solvent.The interaction between cathode,the deposited Li of anode,and solvent promotes the temperature of the battery to rise slowly.When the temperature of the battery reaches more than 60℃,the reaction between lithium metal and solvent is accelerated.After the temperature rises rapidly to the melting point of the separator,it triggers the thermal runaway of the battery due to the short circuit of the battery. | Fengling Yun Shiyang Liu Min Gao Xuanxuan Bi Weijia Zhao Zenghua Chang Minjuan Yuan Jingjing Li Xueling Shen Xiaopeng Qi Ling Tang Yi Cui Yanyan Fang Lihao Guo Shangqian Zhao Xiangjun Zhang Shigang Lu | 2023 | Journal of Energy Chemistry2023，，4： | 0 |
| 6 | Exploring ternary organic photovoltaics for the reduced nonradiative recombination and improved efficiency over 17.23%with a simple large-bandgap small molecular third component显示文摘Ternary strategy is one of the most effective methods to further boost the power conversion efficiency(PCE)of organic photovoltaic cells(OPVs).In terms of high-efficiency PM6:Y6 binary systems,there is still room to further reduce energy_(loss)(E_(loss))through regulating molecular packing and aggregation by introducing a third component in the construction of ternary OPVs.Here we introduce a simple molecule BR1 based on an acceptor-donor-acceptor(A-D-A)structure with a wide bandgap and high crystallinity into PM6:Y6-based OPVs.It is proved that BR1 can be selectively dispersed into the donor phase in the PM6:Y6 and reduce disorder in the ternary blends,thus resulting in lower E_(loss,non-rad)and E_(loss).Furthermore,the mechanism study reveals well-develop phase separation morphology and complemented absorption spectra in the ternary blends,leading to higher charge mobility,suppressed recombination,which concurrently contributes to the significantly improved PCE of 17.23%for the ternary system compared with the binary ones(16.21%).This work provides an effective approach to improve the performance of the PM6:Y6-based OPVs by adopting a ternary strategy with a simple molecule as the third component. | Huanran Feng Yvjie Dai Lihao Guo Di Wang Hao Dong Zhihui Liu Lu Zhang Yvjin Zhu Chen Su Yongsheng Chen Weiwei Wu | 2022 | Nano Research2022，15，4： | 0 |
