“…So there are no free electrons in LDH, resulting in poor conductivity, and the conductivity of Zn-Al-LDH is lower than the 10 À5 S cm À1 measured in our previous work. 18 However, aer calcination, LDH is transformed into LDO containing ZnO species. As a semiconductor, the conductivity of ZnO is about 10 À2 S cm À1 , 39 which is much better than that of LDH.…”

In this work, Zn-Al layered double oxides (Zn-Al-LDO) were prepared via a facile hydrothermal method, followed by calcination treatment in an air atmosphere, and evaluated as anode materials of Zn/Ni batteries. The morphology and structure of as-prepared Zn-Al-LDO and its precursor Zn-Al layered double hydroxide (Zn-Al LDH) were investigated through Fourier transform infrared spectra (FT-IR), Xray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM).Compared to the Zn-Al-LDH precursor, Zn-Al-LDO possesses higher discharge capacity, better reversibility and longer cycle life. The discharge capacity of Zn-Al-LDO remains about 460 mA h g À1 after 1000 cycles. In particular, good rate performance can be observed for a Zn-Al-LDO electrode. The superior properties could be ascribed to improved charge conductivity and the absence of carbonate anions, which make migration of hydroxyl anions smooth to meet the requirements of the electrochemical reaction of the electrode.

“…Preparation of ZnAl‐LDH and MLDH : ZnAl‐LDH as shown in Figure , in detail, Zn(NO 3 ) 2 (15.07 g) and Al(NO 3 ) 3 (5.09 g) was dispersed in deionized water (100 mL), stirred at 25 °C using a magnetic stirrer for 30 min, which was named as A solution. NaOH (5.00 g) and Na 2 (CO 3 ) (2.65 g) were dissolved in deionized water (50 mL), stirred at 25 °C using a magnetic stirrer for 30 min, which was named as B solution.…”

Glass fiber reinforced polytetrafluoroethylene composites (PTFE/GF composites) with the excellent performance have been given considerable attention due to their increasing applications in large architecture areas such as stadiums, amusement parks, parking lots, etc. However, the brittleness of glass fiber can hinder the performance of PTFE/GF composites. The PTFE/MLDH (modified ZnAl‐layered double hydroxide)/GF composites inspired by layer‐layer structure are prepared via the multi‐layered dipping method, which consists of GF acting as a reinforcement, PTFE acting as matrix, and MLDH acting as the layer‐layer structure. The results of study show that the high strength and surperflexibility of PTFE/MLDH/GF composites are higher than pure PTFE/GF composites. Especially, when the PTFE/MLDH/GF composites contain 1.6 wt% MLDH, the folding endurance reaches up to 39 035 times, the tensile strength reaches up to 163.57 MPa, and strain reaches up to 8.33%. More significantly, the strength and surperflexibility are illustrated by a mechanism model and it is used to further broaden the application of PTFE/GF composites in mobile building materials. Moreover, it is discovered that the PTFE/MLDH/GF composites have unique translucent performance and excellent ultraviolet‐shielding properties in this study, which further broaden its range of applications.
