Abstract ：
Acid orange 7 doped poly(3,4-ethylenedioxythiophene)/molybdenum disulfide/reduced graphene oxide (MoS2-RGO@AO7-PEDOT) composite is prepared via a facile two-step approach, where the first step is the molybdenum disulfide (MoS2) nanosheets dispersing on reduced graphene oxide (RGO) evenly using a hydrothermal method, and the second step involves the stable coating of acid orange 7 (AO7) doped poly(3,4-ethylenedioxythiophene) (PEDOT) on the MoS2-RGO surface through chemical oxidation method with AO7 acting as a guide and connector. At a mass ratio of 4:1 between 3,4-ethylenedioxythiophene (EDOT) and MoS2-RGO, MoS2-RGO is coated by AO7 doped PEDOT, and the composite shows a discontinuous lamellar structure without agglomeration of PEDOT, which provides a significant interface between the composite and the electrolyte in favor of increasing the contact area. The large contact area is beneficial for active substances to participate in the redox reaction for charge storage and improving the ion transport efficiency of the electrolyte, which would lead to enhanced electrochemical performance. The composite's specific capacitance in 1 mol L-1 sulfuric acid (H2SO4) is 233 F g-1, which surpasses that of PEDOT by 101%, and the composite retains an impressive 70.6% of its initial specific capacitance after 10,000 cycles. In addition, a flexible all-solid-state supercapacitor is created to investigate its practical application, where H2SO4/polyvinyl alcohol is utilized as the ionic electrolyte and spacer. The supercapacitor demonstrates a maximum energy density of 7.2 Wh kg-1 at a power density of 600 W kg-1, and it maintains 3.52 Wh kg-1 even under high-power density of 4800 W kg-1.

Abstract ：
稀土上转换纳米粒子(UCNPs)因其具有毒性小、化学稳定性好和背景荧光低等优点被用于构建荧光纳米传感器.通过溶剂热法制备核壳UCNPs,采用柠檬酸钠对其进行表面配体交换得到水溶性核壳UCNPs(Cit-CS-UCNPs),以Cit-CS-UCNPs作为荧光传感器的能量供体,二氧化锰(MnO2)纳米片作为荧光传感器的能量受体,采用荧光共振能量转移(FRET)机理,构建了一种用于食品添加剂二氧化氢(H2O2)和叔丁基对苯二酚(TBHQ)检测的荧光纳米传感器(Cit-CS-UCNPs-MnO2).通过扫描电镜(SEM)、荧光光谱和紫外可见吸收光谱(UV-Vis)等分析测试手段对制备的纳米材料的形貌结构和性能进行表征.考察了猝灭剂浓度、孵育温度及孵育时间等实验条件对荧光传感体系检测性能的影响.荧光光谱和UV-Vis实验结果表明,Cit-CS-UCNPs最大发射峰位于654 nm,Cit-CS-UCNPs与MnO2结合后,核壳UCNPs发生荧光猝灭,当存在H2O2时,Cit-CS-UCNPs的荧光恢复,说明在此波段H2O2与MnO2纳米片发生氧化还原反应,MnO2纳米片被还原成Mn2+,逐渐从Cit-CS-UCNPs的表面解离下来;存在TBHQ时,Cit-CS-UCNPs-MnO2与TBHQ体系峰位与TBHQ偏移到253 nm,为TBHQ与MnO2纳米片发生氧化还原反应,使得Cit-CS-UCNPs-MnO2体系中FRET效应减弱,荧光强度回升.SEM结果表明,MnO2纳米片均匀包覆在Cit-CS-UCNPs的周围,在水中仍可保持良好的分散性,表明MnO2纳米片修饰到Cit-CS-UCNPs表面.对猝灭剂高锰酸钾(KMnO4)的浓度进行了优化.结果表明,当KMnO4浓度为10 mol·L-1时,猝灭效率可达90％.对检测条件进行优化,结果表明H2O2的检测孵育时间为25 min时,MnO2和H2O2之间氧化还原反应基本完全,Cit-CS-UCNPs-MnO2荧光恢复值最大;TBHQ的检测孵育时间为30 min.在最佳实验条件下,Cit-CS-UCNPs-MnO2 的荧光强度变化比率与 H2O2 浓度(0～1 000 μmol·L-1)及 TBHQ 浓度(0～0.6 mmol·L-1)分别具有良好的线性关系.保持最佳实验条件,选取食品中存在的代表性金属离子(如K+、Na+、Ca2+和Mg2+)和常见的食品添加剂苯甲酸(BA)、D-葡萄糖(Glu)、山梨酸钾(PS)、蔗糖(Suc)、纳他霉素(Nat)和肌醇(Ino)作为研究对象进行选择性测试,发现与H2O2相比,Cit-CS-UCNPs-MnO2对其他添加物质没有强烈的反应,传感器整体荧光信号波动不大,因此Cit-CS-UCNPs-MnO2对H2O2和TBHQ可进行特异性检测.

Abstract ：
Poly(lactic acid) (PLA) grafted glycidyl neodecanoate (GND) with a single epoxy group (PLA-GND) is prepared in this paper by solid phase grafting, and the effects of different reaction conditions on the grafting percentage of PLA-GND are investigated. Furthermore, PLA-GND is used as a nonreactive compatibilizer to prepare PLA-GND/PLA/poly(butylene adipate-co-terephthalate) (PBAT) composite by melt blending. The results show that PLA-GND has the highest grafting percentage of 2.15% when the feed weight ratio of GND to PLA is 0.2, the feed weight ratio of triphenylphosphine to PLA is 0.02, the additive amount of xylene is 1 mL, the reaction temperature is 120 degrees C, and the reaction time is 115 min. The GND segments of PLA-GND and PBAT segments could form a physical entanglement microdomain because of the similar aliphatic chain of GND and PBAT, which would improve the compatibility of PLA and PBAT. PLA-GND/PLA/PBAT composite has the highest tensile strength, elongation at break, impact strength, crystallinity, heat deformation temperature, and melt flow rate at a PLA-GND content of 5%, which are 38.54 MPa, 118.65%, 15.83 kJ/m2, 5.71%, 65.3 degrees C, and 36.3 g/10 min, 14.53%, 390.90%, 68.94%, 224.43%, 16.19%, and 224.40% higher than those of PLA/PBAT composite, respectively.Highlights PLA grafted GND with a single epoxy group is prepared by solid phase grafting. PLA-GND as a non-reactive compatibilizer compatibilizes PLA/PBAT composite. The similar chain of GND and PBAT is helpful to form the physical entanglement. The physical entanglement is essential to improve compatibility of PLA and PBAT. PLA/PBAT composite has excellent overall performance at a PLA-GND content of 5 wt%.

Abstract ：
Congo red doped poly (3,4-ethylene dioxythiophene)/graphene oxide (GO/CR-PEDOT) composite was prepared by simple chemical oxidation method, where Congo red doped poly (3,4-ethylene dioxythiophene) (CR-PEDOT) evenly and stably coated on the surface of graphene oxide (GO) under the guidance and connection of congo red (CR), respectively. Therefore, GO with a large specific surface area could bring into full play its function as a supporting skeleton to decrease the degree of volume expansion and shrinkage of GO/CR-PEDOT composite in charge/discharge process and improve its specific capacitance and cycle stability. The results showed that the maximum specific capacitance of GO/CR-PEDOT composite was up to 227 F/g when the feeding mass ratio of GO to 3,4-ethylene dioxythiophene was 1:1, which was 110% higher than that of poly (3,4-ethylene dioxythiophene) (PEDOT), and the capacitance retention was 92.3 % after 10,000 cycles. Furthermore, a model of asymmetric supercapacitor was fabricated by using GO/CR-PEDOT composite as positive material, activated carbon as negative material and 1 mol/L Na2SO4 as electrolyte, which exhibited that the energy density was as high as 14.4 Wh/kg when the power density was 996 W/kg and still achieved 9.11 Wh/kg at a high power density of 7999 W/kg.

Abstract ：
Reduced graphene oxide nanofiber (rGONF) modified by anthraquinone-1,5-disulfonate (AQDS) (AQDS-rGONF) was prepared by one-step hydrothermal reaction, and nanocilia-like polyaniline (PANI) grew uniformly on the surface of rGONF under the guidance of AQDS as a starting point of polymerization to fabricate successfully PANI/AQDS-rGONF composite. The results showed that PANI/AQDS-rGONF composite had a larger specific capacitance of 511 F/g than PANI/rGONF composite of 360 F/g or PANI of 312 F/g at a current density of 8 mA/cm(2), and a greater electrochemical stability with the specific capacitance retention of 82.4% than PANI/rGONF of 63.2% or PANI of 52.2% after 2000 cycles, which were closely related to the synergistic effects of special nanocilia-like structure, large specific surface area, rGONF as a supporting skeleton and AQDS as a "bridge". In addition, an asymmetric supercapacitor based on PANI/AQDS-rGONF composite as cathode was assembled, which exhibited a high energy density of 17.9 Wh/kg at a power density of 907 W/kg.
